Alzheimer disease. It is unclear if oral bacopa is beneficial in patients with Alzheimer disease. Details: A small clinical study in patients with Alzheimer disease or mild cognitive impairment shows that taking bacopa 300 mg daily for 12 months does not improve measures of cognitive function or memory when compared with donepezil or baseline measures (109623).
Attention deficit-hyperactivity disorder (ADHD). It is unclear if oral bacopa is beneficial in children with ADHD. Details: A small clinical study in boys 6-14 years of age with symptoms consistent with ADHD but without an official diagnosis shows that taking a specific bacopa supplement (KeenMind - CDRI 08, Flordis) for 14 weeks does not improve symptoms of ADHD but improves some cognitive outcomes including error-making, cognitive flexibility, executive functioning, and sleep when compared with placebo. Bacopa 160 mg was given once daily in those weighing 20-35 kg and twice daily in those over 35 kg (109625). However, another small, open-label study in children aged 6-12 years with ADHD shows that taking a different bacopa supplement (BacoMind, Natural Remedies), 225 mg daily for 6 months, improves symptoms such as restlessness, impulsivity, learning problems, and attention deficit when compared to baseline (97603). The validity of these findings is limited by the lack of blinding or comparator group.
Back pain. Although there is interest in using oral bacopa for back pain, there is insufficient reliable information about the clinical effects of bacopa for this condition.
Cognitive function. Bacopa seems to improve some measures of cognitive function, but data are conflicting. Details: A meta-analysis of 9 small clinical studies, along with more recent clinical research, shows that taking bacopa 300-600 mg daily for at least 12 weeks is not associated with improved measures of cognition including working memory, learning rate, recognition of pictures and words, reaction time, or attention when compared with placebo. However, subgroup analysis of this meta-analysis and another small clinical study show some evidence of improved reaction times, verbal learning, total recall, retention, memory, and information processing in healthy adults when compared with placebo (10058,17946,33287,97605,109624,111520). In children aged 6-8 years old, a very small clinical study shows that taking a syrup containing bacopa extract 350 mg three times daily for 3 months improves visual motor function and immediate memory when compared to baseline (33304). The validity of this finding is limited by the lack of a statistical comparison to the placebo group. Bacopa has also been studied in combination with other ingredients. A study in healthy adults aged 18-60 years shows that taking a single dose of a combination of bacopa 300 mg, American ginseng 100 mg, and coffee fruit extract 100 mg (Bacognize) improves some measures of working memory and attention by a small amount at 45 minutes when compared with placebo (103375). It is unclear if these effects are due to bacopa, other ingredients, or the combination. In contrast, a moderate-sized study in healthy, middle-aged adults shows that taking a combination product containing whole plant bacopa 7.5 grams, gingko biloba, and group B vitamins for 12 weeks does not improve measures of memory, attention, cognition, mood, or stress reactivity when compared with placebo. Subgroup analysis shows a possible benefit of bacopa supplementation on measures of attention in those with an optimal diet at baseline (111334).
Cognitive impairment. It is unclear if oral bacopa is beneficial in patients with cognitive impairment. Details: A small clinical study in patients with mild cognitive impairment or Alzheimer disease shows that taking bacopa 300 mg daily for 12 months does not improve measures of cognitive function or memory when compared with donepezil or baseline (109623).
Congestive heart failure (CHF). Although there is interest in using oral bacopa for CHF, there is insufficient reliable information about the clinical effects of bacopa for this condition.
Depression. It is unclear if oral bacopa is beneficial in patients with depression. Details: Preliminary clinical research in adults with depression who have not responded to citalopram 40 mg daily shows that adding bacopa extract 300 mg twice daily for 4 weeks improves scores on depression rating scales when compared with citalopram alone (103378).
Hypertension. Although there is interest in using oral bacopa for hypertension, there is insufficient reliable information about the clinical effects of bacopa for this condition.
Insomnia. Although there is interest in using oral bacopa for insomnia, there is insufficient reliable information about the clinical effects of bacopa for this condition.
Irritable bowel syndrome (IBS). Bacopa has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients with diarrhea-predominant IBS shows that taking a combination of bacopa and bael (Aegel marmalos) reduces symptoms in 65% of patients, compared with 78% of patients taking clidinium bromide, chlordiazepoxide, and blond psyllium, and 33% taking placebo. Neither treatment is more effective than placebo for preventing relapses (10059).
Parkinson disease. It is unclear if oral bacopa is beneficial in patients with Parkinson disease. Details: A very small study in older adults with Parkinson disease taking levodopa shows that taking a specific bacopa extract (Cognitus, Herbarium) 225 mg or 450 mg daily for 90 days does not improve Parkinsonian or systemic symptoms, motor activity, emotional function, or social outcomes when compared with placebo (111523). The validity of these findings is limited by a small sample size and lack of randomization.
Rheumatoid arthritis (RA). Although there is interest in using oral bacopa for RA, there is insufficient reliable information about the clinical effects of bacopa for this condition.
Sexual dysfunction. Although there is interest in using oral bacopa for sexual dysfunction, there is insufficient reliable information about the clinical effects of bacopa for this condition.
Smoking cessation. Oral bacopa has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A moderate-sized clinical study in adults with a history of smoking 5 or more cigarettes daily for at least 3 years shows that using a specific combination product containing bacopa 100 mg, ashwagandha, Indian gooseberry, tribulus, albizia lebbeck, licorice, clove, ginger, cowhage, holy basil, turmeric (Smotect , Smotect India) twice daily for 3 months reduces the number of cigarettes smoked daily and alveolar carbon monoxide and carboxyhemoglobin levels but does not improve lung capacity when compared with placebo (112115). It is unclear if these effects are due to bacopa, other ingredients, or the combination. More evidence is needed to rate bacopa for these uses.

DANDELION

Constipation. Although there has been interest in using oral dandelion for constipation, there is insufficient reliable information about the clinical effects of dandelion for this purpose.
Dyspepsia. Although there has been interest in using oral dandelion for dyspepsia, there is insufficient reliable information about the clinical effects of dandelion for this purpose.
Flatulence. Although there has been interest in using oral dandelion for flatulence, there is insufficient reliable information about the clinical effects of dandelion for this purpose.
Heart failure. Although there has been interest in using oral dandelion for its diuretic effects in patients with heart failure, there is insufficient reliable information about the clinical effects of dandelion for this purpose.
Joint pain. Although there has been interest in using oral or topical dandelion for joint pain, there is insufficient reliable information about the clinical effects of dandelion for this purpose.
Tonsillitis. It is unclear if oral dandelion is beneficial in patients with tonsillitis. Details: One small clinical study in patients with acute purulent tonsillitis shows that eating soup containing dandelion (pugongying soup) daily for 3 days along with benzylpenicillin sodium 640,000 units daily improves recovery when compared with placebo plus benzylpenicillin sodium. Recovery rates were 36% with the dandelion-containing soup compared to 10% with placebo (18292).
Urinary tract infections (UTIs). Oral dandelion has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in females with recurrent UTIs shows that taking a specific combination of dandelion root and uva ursi leaf extracts three times daily for 1 month reduces the risk of UTI recurrence when compared with placebo at 12-month's follow-up. For every 5 patients treated with this combination over placebo, one additional UTI was prevented (1932). In this combination, uva ursi is used for its antibacterial properties and dandelion is used to increase urination. However, this combination is not recommended for extended use because uva ursi may be unsafe when used long-term. Another small clinical study in premenopausal females with acute, uncomplicated lower UTIs shows that taking a combination product containing dandelion extract 50 mg, D-mannose, prebiotics, arabinogalactan, and astragalus root extract twice daily for five days, along with phenazopyridine and alkylating agents as conventional therapy, improves UTI symptoms and bacteriuria when compared with placebo plus conventional therapy (111757). It is unclear if these effects are due to dandelion, other ingredients, or the combination. More evidence is needed to rate dandelion for these uses.

LAVENDER

Anxiety. Orally, a specific lavender oil product (Silexan) seems to improve anxiety in some patients. Lavender oil aromatherapy and aromatherapy massage also seem to improve chronic and situational anxiety in some patients. Details: Most meta-analyses and clinical trials in patients with mild to severe anxiety show that taking capsules containing a specific lavender oil ingredient (Silexan, Dr Willmar Schwabe GmbH & Co. KG) 80-160 mg orally daily for 6-10 weeks improves anxiety when compared with placebo. However, heterogeneity and small sample sizes limit the validity of these findings (58077,58080,58098,95640,103061,103069). A meta-analysis of a subgroup of these clinical studies shows that taking Silexan 80 mg orally once daily for 10 weeks also reduces anxiety in patients with subthreshold anxiety disorders, which meet some but not all criteria for generalized anxiety disorder (97257). Limited research compares Silexan to the conventional medications paroxetine and lorazepam. One clinical study shows that taking Silexan 80 mg daily for 6 weeks improves anxiety and quality of sleep similarly to low-dose lorazepam (Ativan) 0.5 mg in adults with generalized anxiety disorder (58077). Another clinical study in adults with generalized anxiety disorder shows that taking Silexan 80-160 mg daily for 10 weeks reduces symptom severity similar to paroxetine 20 mg daily (93004). A network meta-analysis suggests that the higher dose of Silexan (160 mg) might be more effective when compared with paroxetine 20 mg or lorazepam 0.5 mg (103069). Limited research has assessed other oral formulations of lavender. A small clinical study in postmenopausal adults with mild to moderate anxiety shows that taking a dried lavender flower powder 500 mg twice daily for 8 weeks reduces anxiety by about 6% when compared with placebo, as measured on the State-Trait Anxiety Inventory Scale (97256). The clinical significance of this improvement is not clear. Meta-analyses of clinical trials in patients with chronic or situational anxiety show that inhalation aromatherapy or aromatherapy massage using lavender oil moderately reduces anxiety when compared with control. Most often, the control group received no intervention although occasionally they received standard or routine care. In some studies, plain water or diluted lemon juice were used as controls. Most treatments with lavender aromatherapy were given as single sessions of 1-30 minutes. However, occasionally multiple sessions were used (101720,103061,109974). Most other individual clinical trials of aromatherapy with lavender, alone or in combination with bergamot, are in agreement with these findings (58103,95637,97258,99713,101722,101724,108752,109854,109981), although some research does not support the use of lavender aromatherapy for anxiety (29504,58053,97258,101724,109853). The poor quality of most of the available research makes it difficult to determine which patients, if any, are most likely to benefit.
Depression. Oral lavender, in the form of tea, tincture, powder, or a specific oil (Silexan), seems to reduce depressive symptoms in some patients. Early research also shows that lavender oil aromatherapy seems to improve symptoms of depression. Details: When used orally, lavender may be beneficial in some patients with depression. A meta-analysis of five clinical trials shows that oral lavender is moderately more beneficial than a control group for reducing symptoms of depression (109860). Most studies included in the analysis were low- to moderate-quality with variation in patient demographics. Studies in the analysis investigated the effects of oral lavender oil or powder in menopausal or postpartum patients, or in patients with major depression, and compared lavender with routine care, placebo, medication, or no intervention. Doses have included powdered lavender leaves 1-2 grams daily for 8 weeks, lavender tea made from 2 grams powder per teabag once or twice daily for 2 weeks, and a specific oral capsule containing lavender oil (Silexan, Dr. Willmar Schwabe GmbH & Co. KG) 80 mg daily for 70 days (103060,104433,109860). Other preliminary clinical research in patients with depressed mood shows that taking Silexan 80 mg daily for 6 weeks can improve depression scores by about 33% when compared to baseline (58098). Also, a small clinical study in patients with mild to moderate depression shows that drinking a tincture of lavender appears to be slightly less effective than imipramine; however, lavender might have some additive antidepressant effects when used in combination with imipramine (9792). The validity of these findings is limited by the lack of a placebo group and small study size. Lavender has also been taken in combination with other products. A small clinical study in patients with depression and anxious distress shows that taking 5 mL of a syrup containing lavender flower extract and Chinese dodder extract twice daily for 6 weeks seems to reduce depression to a similar degree as citalopram 20 mg daily (104437). It is unclear if the benefit is due to lavender, Chinese dodder, or the combination. Lavender oil aromatherapy has also been evaluated. A meta-analysis of nine clinical trials shows that lavender oil aromatherapy is moderately more beneficial than control for reducing symptoms of depression. Most studies included in the analysis were low- to moderate-quality with variation in patient demographics. Studies in the analysis investigated the effects of lavender oil aromatherapy in a variety of patient populations, and no studies were specific to patients with depression. Lavender aromatherapy was compared with no intervention, routine care, other aromatherapy oils, or distilled water (109860). However, in hospitalized patients undergoing microvascular breast reconstruction, lavender oil aromatherapy does not improve symptoms of perioperative depression when compared with coconut oil (109853). Lavender oil has also been studied in combination with other oils as aromatherapy. A small clinical study in community-dwelling older adults shows that inhalation or massage with lavender, sweet orange, and bergamot oils twice weekly for 8 weeks improves depressive symptoms in 55% to 65% of patients when compared with a control (98474). Another small clinical study in postmenopausal adults shows that a combination of aromatherapy with lavender and bergamot oils three times daily for 8 weeks along with routine care modestly improves symptoms of depression when compared with routine care alone (109981). It is unclear if any benefit is due to lavender, other ingredients, or the combination.
Dysmenorrhea. Limited clinical research suggests that lavender oil aromatherapy might reduce dysmenorrhea symptoms. Details: A clinical study in young adults with dysmenorrhea shows that applying 3 drops of lavender oil to a piece of cotton and inhaling for 30 minutes daily for the first 3 days of menstruation modestly reduces pain when compared to inhaling the scent of diluted milk (95635). Another small clinical study in patients with dysmenorrhea shows that applying 3 drops of lavender oil to the hands and inhaling for 5 minutes every 6 hours for the first 3 days of menstruation seems to reduce abdominal pain and backache when compared with inhaling the scent of sesame oil (90510). Lavender oil has also been added to abdominal massage. A clinical crossover study in young females with dysmenorrhea shows that administering a gentle abdominal massage with lavender essential oil for 15 minutes moderately reduces pain immediately after treatment when compared with a massage with petrolatum (58106). It is unclear if the benefit persists after the end of the treatment. Additionally, because all available research has been conducted in the Middle East, it is unclear if these results can be extrapolated to other geographic locations.

POSSIBLY INEFFECTIVE

Cancer-related pain. Using lavender oil for massage or as an aromatherapy diffusion does not seem to provide any additional pain relief in patients with advanced or terminal cancer. Details: Clinical research in patients with advanced or terminal cancer shows that diffusing lavender oil as aromatherapy or using lavender oil for massage does not improve pain scores when compared with control treatments without lavender oil (29504,58053).

Alopecia areata. Topical lavender oil has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with alopecia areata shows that applying lavender oil in combination with essential oils from thyme, rosemary, and cedarwood daily for 7 months seems to improve hair growth in 44% of participants when compared with 15% of those using only carrier oils (5177). It is unclear if this effect is due to lavender oil, other oils, or the combination.
Atopic dermatitis (eczema). Although there is interest in using topical lavender oil for eczema, there is insufficient reliable information about the clinical effects of lavender oil for this condition.
Burns. It is unclear whether lavender oil aromatherapy is beneficial as adjunct treatment for reducing pain associated with dressing changes in children with burns. Details: Preliminary clinical research in young children with second-degree burns shows that lavender oil aromatherapy, provided as 0.5 mL dripped onto a gauze pad and placed 20 cm away from the child's nose for 15 minutes before a dressing change, modestly reduces pain severity at 1 and 30 minutes after the dressing change when compared with placebo aromatherapy with jojoba oil. Use of lavender oil aromatherapy also attenuated increases in heart and respiratory rates after the dressing change (109857).
Canker sores. Topical lavender oil might improve canker sore healing and reduce swelling and pain. Details: A clinical study shows that applying 2 drops of lavender oil to canker sores three times daily might reduce redness, swelling, and pain when compared with placebo (58099).
Colic. It is unclear whether lavender oil aromatherapy massage is beneficial for reducing colic symptoms in infants. Details: A small clinical trial shows that using lavender oil diluted with almond oil to massage the belly of infants for 5-15 minutes beginning at the onset of colic reduces average weekly crying times by about 7 hours when compared with infants not receiving aromatherapy massages (58096). It is unclear if this effect is due to lavender oil, massage, or the combination.
Coronary artery bypass graft (CABG) surgery. Small clinical studies suggest that lavender aromatherapy might modestly improve sleep and reduce pain in patients who have undergone CABG surgery. Details: One small clinical study shows that placing three drops of lavender oil (Barich Essence Company) on the pillow every night for 5 nights modestly improves sleep quality, but not sleep latency, duration, or efficiency, when compared with placebo (109861). Another small clinical study shows that placing 2 drops of lavender oil on a cotton ball for overnight aromatherapy starting on the second evening after surgery modestly improves sleep quality on the second and third nights of use, but not the first night, when compared with distilled water (109856). Also, a small clinical study shows that applying 5 drops of lavender oil 20% to a gauze which is worn around the neck for 30 minutes after CABG surgery modestly reduces postoperative pain on the day of surgery and the day after surgery when compared with pre-aromatherapy pain levels. These changes were greater than those seen in patients inhaling distilled water (109850). However, one small clinical study shows that inhaling 2 drops of lavender oil 2% for 20 minutes on postoperative days 2 and 3 does not reduce mental stress when compared with placebo (93009).
Coronavirus disease 2019 (COVID-19). It is unclear if oral lavender is beneficial for olfactory dysfunction in patients with COVID-19. Details: A small preliminary clinical trial in patients with olfactory dysfunction related to COVID-19 shows that taking lavender syrup 9 mL twice daily for 3 weeks in combination with routine treatments modestly reduces symptoms when compared with routine treatments alone. However, there was no change in symptom scores or the percentage of patients with complete improvement in olfactory or taste dysfunction. The lavender syrup was made by preparing a water extract of the dried aerial parts and mixing with honey and water (109864).
Dementia. Small clinical studies suggest that diffused aromatherapy with lavender oil may modestly improve agitation symptoms in patients with dementia; however, lavender oil applied to the patient or the patient's clothes might not be beneficial. Details: Some small and heterogeneous clinical studies in patients with dementia show that applying lavender oil aromatherapy via a diffuser for either 20 minutes twice daily, 2 hours daily, or once nightly for up to 3 weeks seems to improve agitation when compared with baseline, water, or a sunflower oil placebo (16393,58052,95632). However, using aromatherapy that is applied to the person's clothes or arms does not seem to help. Small clinical studies in patients with moderate or advanced dementia show that applying lavender oil to a pad attached to a patient's shirt does not reduce agitation when compared with placebo (12213,99710). Another clinical study in nursing home residents with dementia and frequent agitated behavior shows that applying 1 mL of 30% lavender oil to each forearm does not reduce agitation or improve mood when compared with applying placebo oil (93014).
Diabetic neuropathy. It is unclear if lavender aromatherapy massage is beneficial for diabetic neuropathy. Details: Preliminary clinical research in patients with neuropathic pain related to diabetes shows that a gentle foot massage with lavender essential oil 3% in sunflower oil for 10 minutes nightly for 1 month reduces neuropathic pain and improves quality of life when compared with a placebo sunflower oil massage or routine care alone (109858).
Fall prevention. It is unclear if lavender aromatherapy prevents falls in elderly patients. Details: A clinical study in nursing home residents aged 65 years or older shows that attaching a patch with lavender oil (Aromaseal Lavender, Hakujuji Co.) onto the neckline of clothing once daily for one year seems to have a non-significant trend toward reduced fall incidence when compared with placebo (58101).
Fatigue. Small clinical studies suggest that lavender aromatherapy may modestly reduce fatigue in patients with underlying medical conditions, such as kidney failure or heart disease. The effects of lavender for fatigue in otherwise healthy adults is unclear. Details: Most small clinical studies in adults with kidney failure show that receiving aromatherapy with lavender essential oil during hemodialysis sessions for 4 weeks reduces fatigue when compared with baseline, a control group, or a placebo group (98524,109867). However, one small clinical study in these patients shows that applying lavender oil for inhalation for 10 minutes during dialysis sessions for 4 weeks does not reduce fatigue when compared with control (95642). Lavender aromatherapy has also been tried in patients hospitalized with various forms of cardiac disease. A small clinical trial shows that placing 3 drops of lavender oil on a cotton ball and inhaling for 20 minutes nightly for 7 days improves fatigue scores by 21 points, compared with a 2-point improvement in those receiving placebo (107959). The validity of these findings is limited due to the short duration of treatment.
Hypertension. Although there is interest in using lavender aromatherapy for hypertension, there is insufficient reliable information about the clinical effects of lavender for this condition.
Insect repellent. Although there is interest in using topical lavender to repel insects, there is insufficient reliable information about the clinical effects of lavender for this condition.
Insomnia. Inhalation aromatherapy or aromatherapy massage with lavender oil may improve some subjective measures of sleep, but results are conflicting and improvements appear minimal at best. Additionally, most small clinical studies suggest it does not improve sleep in hospitalized patients. Details: Lavender oil aromatherapy seems to improve sleep quality in some patients, although it is unclear which patient populations may be most likely to be benefit. A clinical study in healthy college students with self-reported sleep problems shows that wearing a patch containing lavender oil 55 mcL on the chest, in addition to practicing sleep hygiene, improves self-reported sleep quality, but not sleep quantity, when compared with wearing a placebo patch (93012). Another small clinical study in elderly patients that have trouble sleeping in nursing homes shows that placing 2 drops of lavender oil to a cotton pad on a nightstand at bedtime for 4 weeks moderately improves sleep quality and reduces fatigue when compared with control (103062). A meta-analysis of three clinical trials shows that lavender modestly improves postpartum sleep quality when compared with control, including placebo or no intervention. However, each trial used a different form of lavender, including a topical cream, a tea, and aromatherapy. Also, the individual trials included in the analysis show that only the cream and aromatherapy resulted in statistically significant improvements in sleep quality (109866). Conversely, a small clinical study in postmenopausal adults with insomnia who received sleep hygiene guidance shows that inhaling lavender oil 6% before bed nightly for 1 month does not improve sleep quality when compared with sunflower oil. The oil was inhaled from the bottle for two, two-minute sessions and then poured on a cotton ball and placed near the head while sleeping (109852). Lavender aromatherapy has also been evaluated for insomnia in patients with comorbid disease states. A clinical study in patients with insomnia and type 2 diabetes shows that lavender oil aromatherapy for 5 minutes at bedtime nightly for 4 weeks improves sleep when compared with almond oil (103065). Preliminary clinical research in adults with kidney failure shows that foot massage with lavender oil 1.5% for 3 weeks during hemodialysis modestly improves sleep quality when compared with routine care, but is no more effective than sweet orange oil (109859). Another preliminary clinical study in cancer patients shows that receiving aromatherapy as two drops of pure lavender oil applied to a cotton ball and attached to the collar for 20 minutes at bedtime for one week improves sleep when compared with baseline, but seems to be no better than using peppermint oil or a lavender oil 1% control (103063). The validity of this finding is limited because the lavender oil 1% control resulted in notable benefit and might have been an inadequate control treatment. Aromatherapy with lavender oil does not seem to improve sleep in most hospitalized patients, including patients in intermediate care units, hospitalized cardiac patients, and in patients undergoing microvascular breast reconstruction. Aromatherapy treatments have included lavender aromatherapy throughout hospitalization, placing 3 mL of lavender oil 3 feet away from the bed during sleep, and hand and lower leg massage with lavender essential oil 1.5% in sweet almond oil at bedtime (93013,101727,109853). However, studies have generally been small and did not use proper controls. Also, some small clinical studies suggest that lavender aromatherapy might have modest beneficial effects in patients undergoing coronary artery bypass graft (CABG) surgery (109856,109861).
Kidney failure. Small clinical studies suggest that lavender aromatherapy may modestly reduce fatigue and improve sleep quality in adults receiving hemodialysis. Lavender oil massage may also modestly improve symptoms of restless leg syndrome (RLS) in these patients. Details: Multiple small studies have evaluated lavender aromatherapy, provided during hemodialysis sessions, for reducing fatigue. A small clinical study shows that applying 5% lavender essential oil (Barij Essence Pharmaceutical Company) to a cotton ball on the patient's collar for inhalation for 15-20 minutes twice daily during each session for 1 month reduces fatigue by an additional 44% and 40% when compared with baseline and control, respectively (98524). Another preliminary clinical trial shows that applying lavender oil 7% in sweet almond oil to a gauze pad placed 20 cm from the patient's nose for 2 minutes improves fatigue when compared with placebo aromatherapy. By the third week of four total weeks of treatment, most patients given lavender oil aromatherapy had only mild fatigue, compared with moderate or severe fatigue in the control group (109867). Also, a small clinical trial shows that aromatherapy or aromatherapy foot massage with lavender and sweet orange oil for 10-20 minutes during each session for 2 months reduces fatigue when compared with no treatment. Aromatherapy massage seems to be more effective than aromatherapy alone (103068). However, one small clinical study shows that applying the oil for inhalation for 10 minutes during each session for 1 month does not reduce fatigue when compared with control (95642). The difference in these findings might be due to study size, lavender oil concentration, or the frequency and duration of aromatherapy sessions. Lavender aromatherapy has also been evaluated for reducing insomnia in adults on hemodialysis. A small clinical study shows that foot massage with lavender oil 1.5% for 3 weeks during hemodialysis sessions modestly improves sleep quality when compared with routine care. However, it does not seem to be more effective than using sweet orange oil (109859). Some small clinical studies in patients undergoing hemodialysis show that massaging the feet or lower legs with lavender oil reduces the severity of RLS by up to 45% when compared with routine care, massage only, or baby oil as placebo (95638,103064,109865). However, massage with lavender oil does not seem to be more beneficial than glycerin oil 2% or sweet orange oil 1.5% for reducing RLS severity (103064,109859). Doses have included 10-15 mL of 1.5% or 5% lavender oil for 10- to 45-minutes during hemodialysis sessions for 3-4 weeks (95638,103064,109859,109865).
Labor pain. Lavender aromatherapy may help to reduce pain during childbirth. Details: A meta-analysis of clinical trials in pregnant patients in Iran shows that lavender oil aromatherapy applied by various means, such as mask or massage, reduces labor pain when compared with control (104440). All available research has been conducted in Iran, so it is unclear if the benefit can be extrapolated to other geographic locations.
Lice. Topical lavender oil has only been evaluated in combination with other essential oils; its effect when used alone is unclear. Details: Clinical studies in patients with head lice shows that applying lavender oil in combination with tea tree oil reduces the number of hatched and unhatched live lice when compared with control (19188,19189). When applied with tea tree oil three times weekly, lavender oils seems to improve lice eradication when compared with two weekly treatments of pyrethrin and piperonyl butoxide (19189). It is not known if these effects are due to tea tree oil, lavender, or the combination.
Menopausal symptoms. It is unclear if lavender aromatherapy reduces menopausal symptoms such as hot flushes. Details: A meta-analysis and individual clinical studies in postmenopausal adults show that lavender aromatherapy for 4-12 weeks, alone or in combination with other essential oils, reduces menopausal symptoms such as hot flushes when compared with placebo (95634,99711,103067). However, heterogeneity and small sample sizes limit the validity of these findings. A small clinical study in postmenopausal adults shows that aromatherapy with lavender 2% oil for 20 minutes at bedtime every day for 1 month improves quality of life scores when compared to baseline (99711). Another small clinical study in menopausal adults shows that receiving aromatherapy with lavender oil and lemon oil for 5 minutes daily for 30 days seems to improve sleep and quality of life when compared with placebo (104439). However, a small clinical study in postmenopausal adults shows that a combination of lavender and bergamot oils administered via inhalation three times daily for 8 weeks with routine care does not improve sexual function when compared with routine care alone (109981).
Migraine headache. It is unclear if lavender aromatherapy improves migraine symptoms. Details: A small clinical study in patients with migraine headaches shows that rubbing 2-3 drops of lavender oil on the upper lip for inhalation might reduce headache pain and associated symptoms such as nausea and photophobia. Of 129 headaches treated with lavender oil, 92 responded completely or partially, compared with 32 of 68 headaches in the placebo group (18209).
Multiple sclerosis (MS). It is unclear if lavender aromatherapy can improve memory in patients with MS. Details: A small preliminary clinical trial in patients with MS shows that dripping 2 drops of lavender oil (Barij Essence Pharmaceutical Company) on a cotton ball for inhalation for 10 minutes twice daily for 2 weeks improves working memory by a small amount when compared with inhaling distilled water (109855).
Multiple sclerosis-related fatigue. It is unclear if oral lavender is beneficial for reducing fatigue in adults with multiple sclerosis (MS). Details: A small clinical trial in patients with MS shows that taking lavender 600 mg three times daily for 60 days improves fatigue by a large amount when compared with placebo (109851).
Neuropathic pain. Although there is interest in using topical lavender oil for neuropathic pain, there is insufficient reliable information about the clinical effects of lavender for this condition.
Osteoarthritis. It is unclear if lavender aromatherapy with massage reduces osteoarthritis pain. Details: A small clinical study in patients with osteoarthritis shows that applying 5 mL of 3% lavender oil (Barij Essence Pharmaceutical Company) to the knee through self-administered massage three times weekly for 3 weeks can reduce pain by 23% when compared to massage with placebo oil and by 36% when compared with no treatment. However, any benefits of treatment begin to wear off after treatment completion (95645).
Otitis media. Topical lavender oil has only been evaluated in combination with other essential oils; its effect when used alone is unclear. Details: A clinical study in children ages 5-18 years with otitis media and otalgia shows that administering ear drops containing lavender and other herbal extracts, alone or in combination with a topical anesthetic, improves ear pain when compared with baseline. However, it is possible that the pain is self-limited and any pain reduction is due to natural resolution (39500).
Pain (acute). Small clinical studies suggest that lavender aromatherapy may modestly reduce acute pain from needle insertion or other procedures in infants and adults. Details: Two small clinical studies in patients having a needle inserted for hemodialysis shows that inhaling 10% lavender essence for 5 minutes or topically applying 0.3 mL of 100% lavender oil for 5 minutes prior to needle insertion modestly reduces pain when compared with using placebo oil or water (93008,93010). Lavender aromatherapy has also been tried for gynecological exam pain. A clinical study shows that inhaling 10% lavender oil from a heat lamp for 10-15 minutes prior to gynecological exams can reduce pain experienced during the exam up to three-fold when compared to those receiving no treatment (95639). Lavender oil aromatherapy may also reduce vaccination, needle stick, and heel-lancing pain in infants. One clinical study shows that inhaling the scent of lavender oil (Barij Essence Pharmaceutical Company) 0.5% drops for one minute before vaccination modestly reduces pain and decreases crying time by about 20 seconds when compared with sweet almond oil (109869). A small clinical study in term infants shows that being placed in an incubator with lavender essential oil scent overnight before receiving a blood draw modestly reduces overall pain scores when compared with no intervention, but seems to be no different than giving 2 mL of 30% glucose solution (103066). Another small clinical study in premature infants shows that inhaling the scent of 6 lavender oil drops on a cotton ball for 3 minutes before and 30 seconds after a heel-lancing procedure seems to reduce pain scores when compared with exposure to an unscented cotton ball (104442). Lavender oil aromatherapy may also reduce pain due to frenotomy in infants. Preliminary clinical research shows that applying a gauze pad containing one drop of lavender oil under the nose, starting 2 minutes before the frenotomy and continuing throughout the procedure, modestly reduces pain when compared with routine care, which includes swaddling, oral sucrose, and pre-frenotomy sucking. Post-frenotomy crying was also reduced by about 50%, or 10 seconds (109868). Lavender oil seems to be similarly effective to vanilla oil (109810).
Postdural puncture headache. It is unclear if lavender aromatherapy improves postdural puncture headache severity. Details: A small clinical study in patients with postdural puncture headache shows that receiving lavender oil aromatherapy for 15 minutes modestly improves pain immediately after treatment when compared with placebo. However, the pain relief is not maintained at 30 minutes after treatment (104441).
Postoperative nausea and vomiting (PONV). It is unclear if lavender aromatherapy reduces PONV. Details: A small clinical study in postoperative patients shows that inhaling the scent of 2 drops of lavender oil from a cotton pad for 5 minutes improves nausea scores in 83% of people, compared with 44% of those inhaling a placebo. There was no difference in vomiting scores between groups (99712). Another small clinical study in patients after percutaneous nephrolithotomy shows that inhaling the scent of 3 drops of lavender essential oil from a gauze for 5 minutes immediately after the operation, and again 3 and 6 hours later, does not improve nausea or vomiting when compared with a control group that was not receiving aromatherapy (103872).
Postoperative pain. The evidence for the use of lavender aromatherapy for pain after various types of surgical procedures is preliminary and conflicting. Details: Some preliminary clinical research in patients post-Cesarean section shows that, when used in conjunction with standard analgesic therapy, applying 2 drops of lavender oil 2% to a face mask or applying 3 drops of lavender to a cotton ball for inhalation seems to reduce postoperative pain when compared with control (58093,101724). Additionally, preliminary clinical research in patients undergoing coronary artery bypass graft (CABG) surgery shows that applying lavender oil to a gauze which is worn around the neck may modestly reduce postoperative pain on the day of surgery and the day after surgery when compared with distilled water (109850). Also, a small clinical study in children aged 6-12 years post-tonsillectomy shows that rubbing lavender oil onto the palms and inhaling for 3 minutes every 6 hours as needed reduces the use of acetaminophen when compared with control (90513). However, aromatherapy with lavender throughout hospitalization does not seem to improve postoperative pain in patients undergoing microvascular breast reconstruction when compared with coconut oil (109853).
Postpartum complications. It is unclear if topical or inhaled lavender reduces postpartum complications such as pain and swelling. Details: Some clinical research in patients receiving an episiotomy during childbirth shows that adding lavender oil to water or sitz baths for up to 10 days might reduce episiotomy redness and discomfort when compared with using no lavender and standard treatment, such as povidone-iodine. However, findings are mixed as to whether adding lavender oil to baths helps to reduce edema and analgesic use (58085,58092,58116,58121). Lavender aromatherapy has also been studied to improve wellbeing in postpartum patients. A small clinical study in postpartum patients immediately following a natural birth shows that inhaling lavender oil from a cotton ball for 10-15 minutes in the morning, 6 hours later, and at bedtime, improves perceived pain, fatigue, distress, and mood within 1 hour of treatment and also the next morning when compared with placebo (95631).
Postpartum depression. Small clinical studies suggest that aromatherapy with lavender oil may modestly improve or prevent depressive symptoms in postpartum patients. Details: A clinical study in healthy postpartum patients shows that placing 3 drops of lavender essential oil on the palms three times daily for 4 weeks after delivery moderately reduces depressive symptoms and anxiety when compared with usual care only (95637). There is limited research on the benefits of lavender aromatherapy in patients diagnosed with postpartum depression. A small clinical trial in these patients shows that a combination of lavender and rose essential oils, administered via inhalation or aromatherapy massage using hand "M" technique for 15-minute sessions, twice weekly for 4 weeks, reduces depression scores when compared with no intervention (58103).
Pre-procedural anxiety. It is unclear if lavender aromatherapy can reduce preoperative or preprocedural anxiety; results from clinical research are generally of low-quality and benefits are modest at best. Details: A meta-analysis of four small clinical studies in patients undergoing cardiac surgery shows that lavender aromatherapy modestly reduces preoperative anxiety when compared with control (103058). However, the included studies were conducted in the Middle East, and it is unknown if these results are generalizable to other geographic areas. There is conflicting clinical evidence regarding the effect of lavender aromatherapy on anxiety prior to a dental procedure (58078,101725,103059). Small clinical studies also show mixed results as to whether lavender oil aromatherapy applied to a gauze bandage or oxygen mask improves anxiety in patients waiting for breast surgery when compared with usual care. (95641,101729). Lavender aromatherapy might reduce anxiety prior to less risky and extensive procedures such as needle injections. Small clinical studies in adults receiving botulinum toxin type A injections or children receiving dental injections show that lavender oil aromatherapy reduces heart rate and cortisol levels when compared with placebo (58089,104438). Another clinical study in preoperative patients undergoing insertion of a peripheral venous cannula shows that inhalation of 1% lavender oil (Talya Herbal Products) from a gauze pad for 5 minutes modestly reduces pain and anxiety scores and improves patient satisfaction when compared with control (95636). However, a clinical study in patients undergoing a colonoscopy or esophagogastroduodenoscopy shows that inhaling lavender oil does not reduce anxiety, although it does improve patient satisfaction, when compared with placebo (58066). Reasons for conflicting findings are unclear but may relate to the severity of anxiety, the specific outcomes measured, and cultural differences occurring in different geographic locations.
Psychological well-being. It is unclear if topical or inhaled lavender improves well-being. Details: A small clinical study in healthy females shows that adding 3 mL of a mixture containing 20% lavender oil and 80% grapeseed oil to daily baths modestly improves mood when compared with baths containing grapeseed oil alone (15534). However, lavender may not impact well-being in patients with cancer. Clinical research shows that that adding lavender oil for an aromatherapy massage in patients with advanced or terminal cancer does not improve well-being or quality of life when compared with no massage treatment or massage with inert oil (29504,58053).
Restless legs syndrome (RLS). Most preliminary clinical research suggests that lavender oil aromatherapy massage is beneficial for RLS in patients undergoing hemodialysis. Its effect in other patient populations is unclear. Details: Some small clinical studies in patients undergoing hemodialysis show that massaging the feet or lower legs with lavender oil reduces the severity of RLS by up to 45% when compared with routine care, massage only, or baby oil as placebo (95638,103064,109865). However, massage with lavender oil does not seem to be more beneficial than glycerin oil 2% or sweet orange oil 1.5% for reducing RLS severity (103064,109859). Doses have included 10-15 mL of 1.5% or 5% lavender oil for 10 to 45 minutes during hemodialysis sessions for 3-4 weeks (95638,103064,109859,109865).
Stress. Small studies suggest that inhaled lavender oil does not reduce stress in students under academic stress. Details: A meta-analysis of 21 moderate- to high-quality, small- to medium-sized studies shows that inhaling lavender oil modestly reduces stress when compared with control. Most studies included in the analysis have used lavender oil as aromatherapy; other studies have used a cream (109863). Also, inhaling lavender oil 3% in almond oil twice daily for 30 minutes during the exam period does not reduce academic stress or associated symptoms, including headache, blood pressure, or heart rate, in pharmacy students when compared with inhaling an odorless oil, although both were more effective than no intervention (101723).
Toothache. Although there is interest in using topical lavender oil for toothache, there is insufficient reliable information about the clinical effects of lavender oil for this purpose. More evidence is needed to rate lavender for these uses.

LEMON BALM

Depression. Small clinical trials show that oral lemon balm may improve depression when used short-term; the long-term effects are unclear. It is also unclear if lemon balm aromatherapy is beneficial for depression. Details: A meta-analysis of randomized controlled trials in adults with depression and/or anxiety shows that using lemon balm, usually orally, daily for 3-56 days moderately improves depression scores when compared with control. Lemon balm was used orally as 1200-3000 mg daily or as aromatherapy for 30 minutes daily (110136). Other individual studies also show that oral lemon balm may modestly improve depression. A small clinical study in patients with mild or moderate depression shows that taking lemon balm 600 mg with fertilized egg powder (Young Tissue Extract) 1,680 mg daily for 12 weeks improves symptoms when compared with placebo, but not when compared with taking fertilized egg powder alone (19534). Another small clinical study in adults with mostly mild depression shows that taking lemon balm 2 grams daily for 8 weeks moderately improves depressive symptoms when compared with baseline. The improvement appears to be similar to taking lavender powder 2 grams daily or fluoxetine 20 mg daily (104433). However, this study was inadequately powered to detect differences between groups. A small clinical study in adults with type 2 diabetes and mild to moderate depression conducted in Iran shows that taking lemon balm extract capsules 350 mg twice daily for 12 weeks modestly reduces the severity of depression and anxiety based on validated patient-reported questionnaires when compared with placebo (111741). However, the interpretation of these findings is limited by methodological flaws in outcome analysis.
Herpes labialis (cold sores). Topical lemon balm 1% lotion seems to be beneficial for the healing of recurrent cold sores. Details: Clinical research in patients with recurring cold sores shows that applying a cream containing 1% lemon balm dried leaf extract (LomaHerpan, Infectopharm) at the early stages seems to shorten healing time and reduce symptoms of recurring cold sores when compared with placebo (790,9995).
Stress. Oral lemon balm seems to be beneficial for improving experimentally-induced stress in some patients. Details: A small study in healthy adults suggests that a single dose of lemon balm extract 600 mg increases calmness and alertness during laboratory-induced psychological stress when compared with placebo (19524). Another small study in healthy adults shows that a single dose of lemon balm extract (Bluenesse, Vital Solutions) 300 mg added to food or drink reduces anxiety and improves memory and alertness during multi-task cognitive testing when compared with placebo (91733). Lemon balm has also shown benefit when used in combination with other ingredients for stress. Lemon balm 240 mg has been used in combination with valerian 360 mg (Songha Night, Pharmaton Natural Health Products) (19405). Lemon balm 50 mg has been used in combination with valerian root 90 mg, passion flower 90 mg, and butterbur 90 mg (Relaxane, Max Zeller Sӧhne AG) (97276).

Age-related cognitive decline. It is unclear if oral lemon balm is beneficial for improving cognitive function. Details: Preliminary clinical research in adults with age-related cognitive impairment shows that taking lemon balm leaf extract, standardized to contain 500 mg rosmarinic acid, orally daily for 96 weeks does not improve cognitive function scores when compared with placebo (110142).
Alzheimer disease. It is unclear if oral lemon balm is beneficial for improving cognitive function. Details: A small clinical study in elderly patients with mild to moderate Alzheimer disease shows that taking a leaf extract of lemon balm (standardized to citral 500 mcg/mL) 60 drops daily for 4 months seems to reduce agitation and improve cognitive function when compared with placebo (9993). This study was limited by a large number of drop-outs in the placebo group. An even smaller clinical study in patients with mild Alzheimer disease shows that taking lemon balm extract containing 500 mg rosmarinic acid daily for 24 weeks does not seem to improve cognition, but might modestly improve neuropsychiatric symptoms, when compared with placebo (104435). The validity of these findings is limited because the study was not powered to evaluate cognition and neuropsychiatric symptoms.
Anxiety. It is unclear if oral lemon balm or lemon balm aromatherapy is beneficial for reducing anxiety in most patients. Details: A meta-analysis of randomized controlled trials in adults with depression and/or anxiety shows that using lemon balm daily for 3-56 days moderately improves anxiety scores when compared with control. Lemon balm was used orally as 1200-3000 mg daily or as aromatherapy for 30 minutes daily (110136). The validity of this result is limited by high heterogeneity. Also, a small clinical study in patients with mild or moderate anxiety disorders shows that taking a specific standardized lemon balm extract (Cyracos, Naturex SA) 300 mg twice daily reduces anxiety-associated symptoms and improves sleep when compared with baseline (104425). The validity of this finding is limited by the lack of a comparator group. Another small clinical study in adults with type 2 diabetes and mild to moderate depression conducted in Iran shows that taking lemon balm extract capsules 350 mg twice daily for 12 weeks modestly reduces the severity of depression and anxiety based on validated patient-reported questionnaires when compared with placebo (111741).
Attention deficit-hyperactivity disorder (ADHD). Although there is interest in using oral lemon balm for ADHD, there is insufficient reliable information about the clinical effects of lemon balm for this condition.
Chronic bronchitis. Although there is interest in using oral lemon balm for bronchitis, there is insufficient reliable information about the clinical effects of lemon balm for this condition.
Cognitive function. It is unclear if oral lemon balm is beneficial for improving memory and response time in healthy patients. Details: A small study in healthy young adults shows that taking a single dose of lemon balm 1600 mg increases memory accuracy, but may slow performance on timed memory tasks, when compared with placebo (19530). Another small study shows that taking a combination product containing equal parts lemon balm, sage, and rosemary, 5 grams of plant material per 10 mL solution, twice daily for 2 weeks might modestly improve delayed, but not immediate, word recall when compared with placebo in healthy adults 62 years of age or younger. No benefits were seen in adults 63 years of age and older (97277). It is not clear if this effect is due to lemon balm, the other ingredients, or the combination.
Colic. Oral lemon balm has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical studies in breast-fed or formula-fed infants with colic show that giving specific multi-ingredient products containing lemon balm 65-97 mg and German chamomile 9-178 mg, with or without fennel 164 mg and inactivated Lactobacillus acidophilus (ColiMil; ColiMil Plus, Milte Italia SPA), orally twice daily for 1-4 weeks reduces crying times when compared with either placebo or simethicone (16735,96278). Another small clinical study in infants shows that giving 150 mL of a specific herbal tea preparation (Calma-Bebi, Bonomelli), containing German chamomile, vervain, licorice, fennel, and lemon balm, up to three times daily after an episode of colic for one week, modestly reduces colic when compared with placebo water without herbs (19715). It is not known if the benefits of these multi-ingredient preparations are due to lemon balm, other ingredients, or the combination.
Delirium. Oral lemon balm has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in adults in the intensive care unit with agitation and delirium who are receiving quetiapine 50-200 mg every 12 hours shows that taking 5 mL of a syrup containing lemon balm leaf extract 50 mg and valerian root 625 mg orally every 12 hours improves agitation when compared to baseline. Although the improvement appeared to similar to that seen in those taking placebo, no statistical comparison was conducted between groups (106627).
Dementia. It is unclear if oral lemon balm is beneficial for reducing neuropsychiatric symptoms of dementia, such as agitation. Details: A small clinical study in patients with severe dementia and agitation shows that applying a lotion containing essential oil of lemon balm to the faces and hands of patients for 4 weeks reduces agitation based on the Cohen-Mansfield Agitation Inventory (CMAI) scale when compared with applying a placebo lotion (19523). However, another small clinical study in patients with Alzheimer disease and prolonged agitation shows that applying lemon balm oil by gentle massage for 1-2 minutes twice daily for 12 weeks does not reduce agitation when compared with applying placebo oil (19522). The validity of these results is limited by the notable improvement observed in the placebo group, which may have been due to the regular physical touch and increased social interaction that occurred in this group. A small clinical study in patients with dementia shows that inhaling lemon balm oil from a small pad attached to the collar of clothing for 2 hours once daily for 2 weeks does not reduce agitation based on the Neuropsychiatric Inventory (NPI) and CMAI scales when compared with placebo (99710).
Dysmenorrhea. Although there is interest in using oral lemon balm for dysmenorrhea, there is insufficient reliable information about the clinical effects of lemon balm for this condition.
Dyspepsia. Oral lemon balm has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of four small clinical studies in patients with IBS shows that using a specific combination product containing lemon balm (Iberogast, Steigerwald Arzneimittelwerk GmbH) 1 mL orally three times daily over a period of 4 weeks reduces severity of acid reflux, epigastric pain, cramping, nausea, and vomiting when compared with placebo. The combination includes lemon balm, peppermint leaf, German chamomile, caraway, licorice, clown's mustard plant, celandine, angelica, and milk thistle (13089). In another clinical study, taking a similar combination product containing extracts from peppermint leaf, clown's mustard plant, German chamomile flower, caraway, licorice root, and lemon balm (STW 5-II, Steigerwald Arzneimittelwerk GmbH), 1 mL orally three times daily for up to 8 weeks eliminates gastrointestinal symptoms in 40% more dyspepsia patients when compared with placebo (12724).
Headache. Although there is interest in using oral lemon balm for headache, there is insufficient reliable information about the clinical effects of lemon balm for this condition.
Hypertension. It is unclear if oral lemon balm is beneficial for hypertension. Details: Preliminary clinical research in adults with uncontrolled hypertension while on 1-3 active treatments shows that taking lemon balm extract 400 mg, standardized to contain 8 mg rosmarinic acid, orally daily for 4 weeks reduces systolic and diastolic blood pressure by 8% to 14% and 11% to 16%, respectively, when compared with baseline. These improvements were significant when compared with placebo (110138).
Hyperthyroidism. Although there is interest in using oral lemon balm for hyperthyroidism, there is insufficient reliable information about the clinical effects of lemon balm for this condition.
Insect repellent. Although there is interest in using topical lemon balm as insect repellant, there is insufficient reliable information about the clinical effects of lemon balm for this condition.
Insomnia. Oral lemon balm has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Taking a specific combination product providing lemon balm leaf extract 80 mg and valerian root extract 160 mg (Euvegal forte, Dr. Willmar Schwabe Pharmaceuticals) 2-3 times daily appears to improve the quality and quantity of sleep in healthy people and those diagnosed with insomnia or sleeping disorders (10423,19528,19536). However, lower daily doses may not improve sleep (10421). Other clinical research in healthy adults with insomnia shows that using a combination product containing ground lemon balm herb 1000 mg and aqueous extract of Nepeta menthoides 400 mg at bedtime for 4 weeks improves sleep quality and sleep duration and reduces sleep disturbance, sleep latency, and daytime dysfunction when compared with placebo (97278). A clinical study in children 12 years and younger shows that a specific combination product containing lemon balm leaf extract 80 mg and valerian root extract 160 mg (Euvegal forte, Dr. Willmar Schwabe Pharmaceuticals) 1-2 tablets once or twice daily might decrease symptoms of restlessness and dyssomnia when compared to baseline (14416). It is unclear if these effects are due to lemon balm, other ingredients, or the combinations.
Irritable bowel syndrome (IBS). Oral lemon balm has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with IBS shows that using 30 drops of a combination product providing lemon balm, spearmint, and coriander (Carmint, PurSina Pharmacy) three times daily after meals for 8 weeks reduces abdominal pain and discomfort when added to standard treatment with loperamide or psyllium, compared to standard treatment alone (19535). It is not known if the effect is due to lemon balm, the other ingredients, or the combination.
Menopausal symptoms. Oral lemon balm has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in postmenopausal adults with sleep disturbances shows that taking lemon balm leaf 250 mg and fennel fruit 250 mg orally once daily for 8 weeks improves menopausal symptoms including vasomotor, psychomotor-social, physical, and sexual symptoms, by 24% to 38% when compared with baseline. These improvements were significant when compared with placebo (110137).
Pain (acute). It is unclear if lemon balm aromatherapy is beneficial for reducing pain in patients with acute coronary syndrome. Details: A small clinical study in patients with acute coronary syndrome presenting to the emergency department shows that aromatherapy with lemon balm leaf and stem essential oil 1% for 10 minutes twice on the day of presentation modestly reduces chest pain scores when compared with placebo. However, pain was no longer different between groups within 15 minutes after the second aromatherapy session (110139).
Postpartum complications. Oral lemon balm might reduce postpartum pain in some patients; however, it's not clear if it is beneficial for other postpartum complications. Details: A small clinical study shows that taking lemon balm leaf extract 395 mg every 6 hours for 24 hours following childbirth is slightly more effective for reducing postpartum pain when compared with taking mefenamic acid 250 mg using the same dosing schedule (101763).
Psoriasis. Oral lemon balm has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with mild to moderate psoriasis shows that taking an oral combination product containing lemon balm, rose hip, and fennel as 10 mL three times daily for 12 weeks improves pruritus and psoriasis scores by 45% and 49%, respectively, when compared with baseline. In contrast, these scores worsened in the placebo group (110141). The validity of this finding is limited by the lack of statistical comparison between groups.
Somatic symptom disorder. Oral lemon balm has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A clinical study in individuals with somatic symptom disorder shows that taking one tablet of a combination product three times daily for 2 weeks seems to improve symptoms of depression and anxiety when compared with placebo. Each tablet of this product contains lemon balm leaf extract 60 mg, valerian root extract 90 mg, and passionflower herb extract 90 mg (19701). It is not known if the effect is due to lemon balm, other ingredients, or the combination.
Ventricular arrhythmias. It is unclear if oral lemon balm leaf tea is beneficial for patients with premature ventricular contraction (PVC). Details: Preliminary clinical research in adults with low to moderate PVCs shows that drinking lemon balm leaf tea twice daily for 12 weeks reduces the frequency of PVCs by 32% when compared with baseline. This improvement was significant when compared with no treatment. Lemon balm tea also modestly improved heart rate, but not left ventricular ejection fraction, when compared with no treatment. The tea was prepared by steeping lemon balm leaf 2 grams in 250 mL of boiling water (110140). More evidence is needed to rate lemon balm for these uses.

OATS (Oat)

LIKELY EFFECTIVE

Coronary heart disease (CHD). A diet high in soluble fiber, such as that found in oats, reduces the risk of CHD. Details: Clinical research shows that a diet containing foods high in fiber, such as oats, oat bran, or whole oat flour, reduces the risk of CHD (2737,4960,4962,4963,4964,4965,4966,4967,4968). In 1993, the US Food and Drug Administration (FDA) approved a health claim stating that consuming at least 3 grams of soluble fiber per day, as part of a diet low in saturated fat and cholesterol, may reduce the risk of CHD (102336). However, clinical studies show that at least 3.6 grams of soluble fiber daily is needed to reduce the risk of CHD (5786,5787,5788,5794,5795,5796).
Hypercholesterolemia. A diet rich in soluble fiber, such as that found in oats, can reduce cholesterol by a moderate amount. Details: Oats, oat bran, and other soluble fibers can modestly reduce total and low-density lipoprotein (LDL) cholesterol when consumed as part of a diet low in saturated fat. Consuming 56-150 grams of whole oat products such as oatmeal and oat bran, containing 3.6-10 grams of soluble fiber daily, can significantly lower total and LDL cholesterol levels. For each gram of soluble fiber consumed, total cholesterol decreases by about 1.4 mg/dL and LDL by about 1.2 mg/dL. Eating 3-10 grams of soluble fiber daily can reduce total cholesterol by about 4-14 mg/dL (4976,4977,5786,5788,5792,5794,5795,8521,107749); however, doses greater than 10 grams daily don't seem to increase effectiveness (5788). Eating three bowls of oatmeal (28 gram servings) daily can decrease total cholesterol by about 5 mg/dL (4972,4973,4974,4975,4976,4977,5786,5788,6188). Oat bran products, such as oat bran muffins and oat bran flakes, may vary in their ability to lower cholesterol, depending on the total soluble fiber content and other dietary variables (6188). Whole oat products might be more effective for lowering LDL and total cholesterol than foods containing oat bran plus soluble fiber (10145).

Diabetes. A diet rich in whole grains, such as oats, may help prevent diabetes or improve blood glucose control in patients with type 1, type 2, or gestational diabetes. Details: Population research shows that for every 16 gram daily serving of whole grains, including oats, there is a 7% to 11% lower risk of developing type 2 diabetes (100622). There is also evidence that consuming oats can decrease blood glucose and insulin levels, as well as lipid levels, in patients with diabetes. The glycemic effects of oats depend on the level of processing of the oat products. Consuming intact oat kernels or thick-cut oats (>0.6 mm) reduces postprandial blood glucose and insulin, but consuming thin-cut, or "quick", oats has no effect (105536). Clinical research shows that consuming oats and oat bran for 4-8 weeks decreases pre-prandial blood glucose, 24-hour plasma glucose, glycated hemoglobin (HbA1c), insulin levels, and low-density lipoprotein (LDL) cholesterol in people with type 2 diabetes (4980,4982,6266,103345). Various doses have been used, including 3 grams of soluble fiber daily, or bread providing 34 grams of total fiber daily (9 grams of soluble fiber) (4961,4980). Additional clinical research in obese adults with type 2 diabetes shows that eating whole grain oats 50-100 grams daily in place of other carbohydrates reduces postprandial blood glucose by 19-27 mg/dL when compared with other carbohydrates in a healthy diet. After 1 year, the groups consuming 50 grams and 100 grams of oats had an additional 0.48% and 0.64% reduction in HbA1c, respectively, when compared with the regular healthy diet group (97520). There is also some evidence that consuming oats 50 grams daily, containing 25 grams of soluble fiber, might be more effective for improving glycemic control and decreasing hyperinsulinemia than the standard moderate fiber diet recommended by the American Diabetes Association (ADA) (6266). Oats have also been evaluated in adolescents with type 1 diabetes. One very small clinical study shows that taking 50 grams of a specific oat product (Betaglucare), providing beta-glucans 6 grams, in three divided doses daily for one week is beneficial for glycemic control and variability when compared with a standard diet without beta-glucans or with taking only 25 grams of the product daily. Maximal, mean, and pre- and post-meal blood glucose levels were modestly lower, and minimal blood glucose levels were modestly higher. Most measures of glycemic variability were statistically different, although there were no differences in the duration of hypoglycemia or hyperglycemia between groups (105261). Oats have also been evaluated in patients with gestational diabetes. A randomized, controlled trial shows that taking 30 grams of a specific oat bran product (OAB; Golden Light Cup Company) orally twice daily at lunch and dinner for 4 weeks improves mean fasting blood glucose and two-hour postprandial glucose when compared with a control group. After 4 weeks, the mean fasting blood glucose and 2-hour postprandial glucose in the treatment group were 85 mg/dL and 104 mg/dL, respectively, compared with 93 mg/dL and 117 mg/dL, respectively, in the control group (107751). The validity of this study is limited by the short treatment duration and lack of follow-up.
Gastric cancer. A diet rich in soluble fiber, such as that found in oats, might reduce the risk of gastric cancer. Details: Observational research has found that consuming a diet that includes cereal fiber, such as oats and oat bran, might reduce the incidence of gastric cancer (10435).

POSSIBLY INEFFECTIVE

Colorectal cancer. Regular consumption of oats does not seem to reduce the risk of colorectal cancer. Details: Observational research has found that consuming oat bran or oats orally doesn't seem to reduce the risk of colon cancer. Additionally, consuming fiber, including oat-bran fiber, is not associated with a reduction in the risk for recurrence of colorectal adenomas (4820,5104).

Acne. Although there is interest in using topical oats for acne, there is insufficient reliable information about the clinical effects of oats for this purpose.
Anxiety. Although there is interest in using oral oats for anxiety, there is insufficient reliable information about the clinical effects of oats for this purpose.
Atopic dermatitis (eczema). Topical colloidal oatmeal cream may be beneficial in patients with atopic dermatitis. Details: Preliminary clinical research shows that applying a cream containing colloidal oatmeal 1% daily for 2 weeks has a moderate effect on the severity of atopic dermatitis when compared with baseline (103344). The validity of this finding is limited by the lack of a comparator group. Other research suggests that colloidal oatmeal may be beneficial when used in combination with topical steroids. Clinical research shows that the benefits obtained from applying an ointment containing fluocinolone 0.025% to the hands for 2 weeks were better maintained in the patients who also used a cream containing colloidal oatmeal 1% during this time period and for an additional 4 weeks when compared with patients using fluocinolone and the cream base without colloidal oatmeal. Quality of life was also improved in the patients using colloidal oatmeal (103340).
Breast cancer. Observational research suggests that regular oatmeal intake may be associated with reduced mortality from breast cancer. Details: Population research in postmenopausal patients has found that those who have eaten 50 grams of oatmeal daily prior to a breast cancer diagnosis have a 20% reduced risk of all-cause mortality in the 7 years following the diagnosis when compared with patients who have not eaten oatmeal. However, no benefit was seen when post-diagnostic oatmeal intakes were examined (103343).
Burns. Although there is interest in using topical oats for burns, there is insufficient reliable information about the clinical effects of oats for this purpose.
Chronic fatigue syndrome (CFS). Although there is interest in using oral oats for CFS, there is insufficient reliable information about the clinical effects of oats for this purpose.
Cognitive function. It is unclear if oral oats are beneficial in healthy adults with mild memory impairment. Details: Preliminary clinical research in healthy middle-aged adults with self-reported memory decline shows that consuming a specific wild green-oats extract (Neuravena, Frutarom) 800 mg as a single dose improves overall speed, but not overall accuracy, of cognitive performance when compared with placebo. However, a higher dose of 1600 mg was ineffective (97519).
Dry skin. It is unclear if applying lotion containing colloidal oat extract improves dry skin to a greater extent than other lotion products. Details: Preliminary clinical research shows that applying a lotion containing colloidal oat extract (Aveeno Active Naturals Skin Relief 24Hr Moisturizing Lotion, Johnson & Johnson) twice daily for 2 weeks improves itchiness, cracking, scaling, dryness, and roughness when compared to baseline in females with dry skin (91458). Additional preliminary clinical research shows that applying a colloidal oatmeal lotion to the legs twice daily for three weeks reduces skin dryness and improves skin integrity when compared to baseline in adults with dry skin (97518). The validity of these findings is limited by the lack of a comparator group.
Exercise-induced muscle soreness. It is unclear if oral oats are beneficial for exercise-induced muscle soreness. Details: A small clinical trial shows that eating two cookies containing oat flour 60 grams daily for 8 weeks reduces muscle soreness 48 or 72 hours after downhill running when compared with baseline (103341).
Fat redistribution syndrome. It is unclear if oral oats are beneficial for fat redistribution syndrome. Details: Consumption of a high fiber diet, including oats, with adequate energy and protein might prevent fat deposition in patients with HIV. A one-gram increase in total dietary fiber may decrease the risk of fat deposition by 7% (12517).
Gallbladder disease. Although there is interest in using oral oats for gallbladder disease, there is insufficient reliable information about the clinical effects of oats for this purpose.
Hypertension. It is unclear if oral oats are beneficial for hypertension. Details: Observational research has found that consumption of oats as oatmeal or oat cereal does not seem to reduce diastolic blood pressure (DBP) or systolic blood pressure (SBP) in males with minor elevations in blood pressure (2956). A randomized, controlled trial in patients with stage 1 hypertension receiving dietary guidance shows that taking 30 grams of oat bran, providing 8.9 grams of dietary fiber, once daily with breakfast or in between meals for 3 months improves various blood pressure measures when compared with dietary guidance alone. After 3 months of treatment, 24-hour maximum SBP and DBP decreased by 14 mmHg and 11 mmHg, respectively, and office SBP and DBP decreased by 15 mmHg and 10 mmHg, respectively. Oat consumption may also have impacted antihypertensive medication use. Two patients in the control group increased doses of antihypertensive medications, whereas 6 patients in the treatment group decreased doses and 1 patient discontinued use (107750). The effect of oral oat bran on patients with stage 2 hypertension or pre-hypertension is unknown.
Irritable bowel syndrome (IBS). Although there is interest in using oral oats for IBS, there is insufficient reliable information about the clinical effects of oats for this purpose.
Metabolic syndrome. Limited research suggests that oats may not be beneficial for metabolic syndrome. Details: Preliminary clinical research in adults with metabolic syndrome shows that adding oat bran 40 grams daily for 6 weeks to a low-calorie diet does not reduce the incidence of metabolic syndrome. Oat bran also does not improve body weight, blood pressure, low-density lipoprotein (LDL) cholesterol, triglycerides, or blood glucose levels when compared with a low-calorie diet alone in patients with metabolic syndrome (103342).
Osteoarthritis. Although there is interest in using oral oats for osteoarthritis, there is insufficient reliable information about the clinical effects of oats for this condition.
Pruritus. Applying oat lotion topically may improve some types of pruritus. Details: Preliminary clinical research shows that applying an oat lotion (Espanol) twice daily for up to 2 weeks can decrease itching intensity by about 20% when compared to baseline in patients with pruritus associated with chronic kidney disease (uremic pruritus). This decrease is similar to the effects of applying vinegar 5% solution or taking hydroxyzine 10 mg orally. However, applying the oat lotion does not appear to decrease the frequency of itching (91457).
Psoriasis. Although there is interest in using topical oats for psoriasis, there is insufficient reliable information about the clinical effects of oats for this purpose.
Rheumatoid arthritis (RA). Although there is interest in using oral oats for RA, there is insufficient reliable information about the clinical effects of oats for this purpose.
Stroke. It is unclear if oral oats are beneficial for reducing the risk of stroke. Details: Population research suggests that consuming oatmeal for breakfast once weekly might reduce the incidence of stroke by a small amount when compared with consuming white bread or eggs for breakfast (103337).
Ulcerative colitis. Oral oats have only been evaluated in combination with other ingredients; their effect when used alone is unclear. Details: Preliminary clinical research shows that taking a specific oat-based product (Profermin, Nordisk Rebalance) containing fermented oat flour, Lactobacillus plantarum, barley malt flour, and lecithin, 250 mL orally twice daily for 8 weeks, reduces disease activity and increases remission in about two-fold more patients with relapsing ulcerative colitis, when compared with treatment with a specific nutritional beverage (Fresubin Original, Fresenius Kabi) (90271).
Wound healing. Although there is interest in using topical oats for wound healing, there is insufficient reliable information about the clinical effects of oats for this purpose. More evidence is needed to rate oats for these uses.

Anxiety. Oral passion flower has a long history of use as a sedative and may improve symptoms of anxiety in some patients. Details: Preliminary clinical research shows that taking a specific dried alcoholic extract of passion flower (Sedanxio, Tilman SA) 400 mg orally twice daily for 2-8 weeks reduces the severity of non-specific anxiety when compared to baseline (88198). The validity of this finding is limited by the lack of a placebo group. Passionflower has also been evaluated as an adjunct to conventional medication. One clinical small study in patients with generalized anxiety disorder shows that taking a specific passion flower extract (Pasipay, Iran Darouk Pharmaceutical Company) 15 drops three times daily along with sertraline 50-100 mg daily for one month reduces anxiety when compared with taking sertraline alone (95036). Passion flower has also been compared to conventional treatments. One preliminary clinical study shows that taking passion flower extract 90-180 mg daily reduces symptoms of non-specific anxiety when compared to baseline, and seems to be comparable to taking mexazolam (15391). A small clinical study in patients with generalized anxiety disorder shows that taking a specific passion flower extract (Pasipay, Iran Darouk Pharmaceutical Company) 45 drops orally once daily for 28 days reduces anxiety similarly to oxazepam 30 mg daily. However, passion flower appears to have a slower onset of action than oxazepam (8007). This finding is limited because it did not utilize a therapeutic dosing regimen for oxazepam, which is given 3-4 times daily to account for its short half-life. Passion flower has also been studied in combination with other ingredients. A small clinical study in healthy adults shows that taking a combination of herbal extracts containing passion flower 40 mg, valerian root, black horehound, and hawthorn (Euphytose, Bayer HealthCare) 6 times daily with meals for 14 days reduces anxiety and sympathetic and autonomic nervous system activation in response to a psychosocial stressor when compared with placebo (111222). It is unclear if these effects are due to valerian, other ingredients, or the combination.
Pre-procedural anxiety. Oral passion flower modestly reduces preoperative anxiety. Details: Two small clinical studies in adults awaiting dental surgery or inguinal hernia repair surgery shows that taking a specific passion flower extract (Pasipay, Iran Darouk Pharmaceutical Company) reduces preoperative anxiety when compared with placebo. Passion flower extract was given as 20 drops or 500 mg 90 minutes prior to surgery, with or without another dose on the evening before surgery (88195,88196). Another small clinical study shows that drinking 5 mL of syrup containing passion flower aqueous extract (Passiflora syrup, Sandoz) 700 mg orally 30 minutes before epidural catheter insertion for inguinal hernia repair surgery seems to attenuate anxiety; the placebo group experienced a significant increase in anxiety (88194). This finding is limited because there were no statistical comparisons conducted between groups. Passion flower has also been compared with conventional medications. Three clinical studies show that taking passion flower prior to dental surgery decreases preoperative anxiety similarly to oral midazolam 15 mg. One study used passion flower 260 mg, administered 30 minutes prior to the surgery (95038), the second used 500 mg, administered 60 minutes prior (104206), and the third used 600 mg, administered 45 minutes prior (110014). Of the two studies that evaluated patient preference, patients in one study preferred midazolam, possibly due to its ability to cause perioperative amnesia (95038), whereas there was no preference in the other study (110014). Another clinical study shows that taking passion flower 1000 mg one hour prior to elective minor or moderate surgery reduces preoperative anxiety similarly to melatonin 6 mg; however, passion flower seems to cause more cognitive impairment than melatonin (95037).

Adjustment disorders. Oral passion flower has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One clinical study in patients with adjustment disorder with anxious mood shows that taking two tablets of a specific combination product (Euphytose, Bayer Healthcare) three times daily seems to decrease anxiety symptoms when compared with placebo. One tablet contains the dry extracts of passion flower 40 mg, valerian 40 mg, hawthorn 10 mg, and black horehound 10 mg, as well as the caffeine-containing stimulant herbs kola nut 15 mg and guarana 15 mg (6250). It is unclear if this effect is due to passion flower, other ingredients, or the combination.
Alcohol use disorder. Oral passion flower has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults experiencing alcohol withdrawal symptoms shows that taking one capsule of a combination product (Relief) three times daily for 15 days reduces the frequency of excessive sweating, reduces serum liver enzyme levels, and improves appetite and quality of life when compared to baseline. One capsule contains passion flower extract 30 mg, black seed extract 100 mg, cocoa extract 90 mg, radish extract 165 mg, and saffron extract 15 mg (97280). The validity of these findings is limited by the lack of a comparator group.
Attention deficit-hyperactivity disorder (ADHD). It is unclear if oral passion flower is beneficial in patients with ADHD. Details: A small clinical trial in children aged 6-13 years with ADHD shows that taking tablets of passion flower (Pasipay, Iran Darouk Pharmaceutical Company) 0.02 mg/kg orally twice daily for 8 weeks reduces parent and teacher ratings of ADHD symptoms no better than taking methylphenidate (0.5 mg/kg twice daily) (88197).
Benzodiazepine withdrawal. It is unclear if oral passion flower is beneficial for benzodiazepine withdrawal. Details: A moderate-sized observational study in adults with depression or anxiety on antidepressants undergoing a benzodiazepine taper after chronic benzodiazepine use suggests that taking a specific dry extract of passion flower (Tractana, Baldacci) 200-600 mg daily for 3 months is associated with a faster benzodiazepine dose reduction and greater percentage of patients with at least 50% reduction or complete benzodiazepine discontinuation after 1 and 3 months from taper initiation when compared with control (111651). The validity of these effects is limited by a lack of placebo group and the retrospective observational study design.
Congestive heart failure (CHF). Oral passion flower has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients with mild CHF shows that taking a combination of passion flower and hawthorn extracts 2 mL three times daily for 6 weeks increases six-minute walking distance when compared with placebo. However, it does not appear to improve exercise capacity on a bicycle ergometer test (19201). It is unclear if this effect is due to passion flower, hawthorn, or the combination. Additionally, hawthorn has been evaluated alone for the management of CHF, with some research suggesting that although it may improve symptoms, it may also be associated with worsened clinical outcomes.
Fibromyalgia. Although there is interest in using oral passion flower for fibromyalgia, there is insufficient reliable information about the clinical effects of passion flower for this condition.
Insomnia. Small clinical studies suggest that oral passion flower may modestly improve sleep quality in patients with insomnia and poor sleep quality. Details: Some preliminary clinical research in adults with insomnia shows that taking passion flower extract 60 mg every evening before bedtime for 2 weeks increases total sleep time by around 23 minutes, but doesn't seem to improve sleep efficiency, sleep latency, or awakening after sleep onset, when compared with placebo (102866). Another smaller clinical study in young adults with mild fluctuations in sleep quality shows that drinking tea prepared by steeping passion flower aerial parts 2 grams in 250 mL of boiling water for 10 minutes every evening, about an hour before bedtime for 7 nights, improves subjective ratings of sleep quality, but not other sleep parameters, when compared with placebo (parsley tea) (17374). Passion flower has also been studied in combination with other ingredients. One small clinical study in adults with primary insomnia shows that taking a specific combination product containing passion flower 80 mg, valerian 300 mg, and hops 30 mg (NSF-3, M/s Tablets India) orally at bedtime for 2 weeks yields similar effects on subjective measures of sleep as zolpidem 10 mg nightly (88193).
Menopausal symptoms. Although there is interest in using oral passion flower for menopausal symptoms, there is insufficient reliable information about the clinical effects of passion flower for this purpose.
Muscle cramps. Although there is interest in using oral passion flower for muscle cramps, there is insufficient reliable information about the clinical effects of passion flower for this purpose.
Neuropathic pain. Although there is interest in using oral passion flower for neuropathic pain, there is insufficient reliable information about the clinical effects of passion flower for this condition.
Opioid withdrawal. It is unclear if oral passion flower helps to prevent opioid withdrawal. Details: A small preliminary clinical study in adults who are completing an inpatient withdrawal program for opioid addiction shows that taking passion flower liquid extract 60 drops, in combination with clonidine 0.8 mg daily, is better than clonidine alone when used for reducing symptoms such as anxiety, irritability, insomnia, and agitation. However, the combination is no better than clonidine alone for reducing physical symptoms such as tremor and nausea (2303).
Seizures. Although there is interest in using oral passion flower for seizures, there is insufficient reliable information about the clinical effects of passion flower for this condition.
Stress. Oral passion flower has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in healthy adults shows that taking a specific combination product (Relaxane, Max Zeller Söhne AG) containing passion flower 90 mg, lemon balm 50 mg, valerian 90 mg, and butterbur 90 mg three times daily for 3 days modestly reduces subjective anxiety scores during social stress testing when compared with placebo or no treatment (97276). It is unclear if this effect is due to passion flower, other ingredients, or the combination. More evidence is needed to rate passion flower for these uses.

Asthma. It is unclear if dietary citrus fruits are beneficial in patients with asthma. Details: There is some evidence that consumption of vitamin C-rich citrus fruits, including sweet orange and others, might improve lung function in people with asthma. However, this is controversial. Some studies show that intake of citrus fruits 1-2 times per week produces significant benefit (6049,6055,6056), while other studies have not found this benefit (6057,6058).
Common cold. It is unclear if drinking sweet orange juice prevents the common cold. Details: Preliminary clinical research in healthy individuals ages 17 to 25 years suggests that drinking sweet orange juice 180 mL daily for 72 days might decrease the risk of developing common cold-related symptoms (15328).
Depression. It is unclear if drinking sweet orange juice or using sweet orange essential oil as aromatherapy is beneficial for depression. Details: Preliminary clinical research in adults with depression shows that drinking flavonoid-rich sweet orange juice 190 mL three times daily for 8 weeks modestly improves depression scores when compared to baseline, but not when compared with a low-flavonoid orange drink (110045). Sweet orange has also been studied as part of a combination aromatherapy. A very small clinical study in community-dwelling older adults shows that massage therapy to the upper body with sweet orange, lavender, and bergamot oils twice weekly for 8 weeks improves symptoms of depression in 65% of patients when compared with no intervention. Twice weekly inhalation of the same essential oils via nebulizer, without massage, also improves symptoms of depression in 55% of patients when compared with no intervention (98474).
Hypercholesterolemia. It is unclear if drinking sweet orange juice improves blood lipid levels. Details: A very small clinical study in hypercholesterolemic patients shows that drinking large amounts of sweet orange juice (750 mL daily for four weeks) seems to increase high-density lipoprotein (HDL) cholesterol by 21% and reduce the ratio of low-density lipoprotein (LDL) to HDL cholesterol by 16% when compared to baseline. This effect was not seen with 250-500 mL of sweet orange juice. Because consumption of this large amount of juice daily provides approximately 20% of the daily energy requirement, this regimen may not be practical (3340).
Insomnia. Sweet orange essential oil as aromatherapy has only been evaluated in combination with other essential oils; its effect when used alone is unclear. Details: Preliminary clinical research in adults undergoing hemodialysis shows that inhaling aromatherapy with sweet orange and lavender oil nightly before bed for one month improves overall sleep quality by 72% and fatigue by about 78% when compared with no treatment (98508).
Kidney failure. It is unclear if sweet orange oil massage can improve fatigue or symptoms of restless leg syndrome (RLS) in adults receiving hemodialysis. Details: A small clinical study shows that receiving an 18-minute foot massage with sweet orange oil 1.5% for 3 weeks during hemodialysis sessions modestly improves sleep quality and symptoms of RLS when compared with routine care. However, it does not seem to be more effective than using lavender oil (109859).
Kidney stones (nephrolithiasis). It is unclear if drinking sweet orange juice is beneficial for preventing kidney stones. Details: Consuming 400 mL of sweet orange juice three times a day, providing a total of 100 mEq of citrate daily, increases urinary pH and urinary citrate levels (15171). Theoretically, this might reduce kidney stone formation in patients with calcium nephrolithiasis. However, this outcome has not been evaluated in clinical research.
Obesity. It is unclear if drinking sweet orange juice or taking oral sweet orange extract improves weight loss or other metabolic parameters in adults with overweight or obesity. Most studies suggest that any effects are unlikely to be considered clinically relevant. Details: Some preliminary clinical research in adults with overweight or obesity shows that taking a specific sweet orange extract (Morosil, Bionap S.R.L.) 400 mg orally once daily for six months reduces waist circumference, body weight, fat mass, and body mass index (BMI) by 2% to 5% when compared with placebo (110046). However, other preliminary clinical research in this population shows that drinking red sweet orange juice 750 mL daily for 8 weeks does not reduce body weight or BMI when compared with baseline (92309). A meta-analysis of clinical research in adults, most of whom were overweight or obese at baseline, shows that drinking 250-750 mL of various types of sweet orange juice daily for 2-12 weeks does not reduce body weight, BMI, waist circumference, or body fat percentage (BFP) when compared with control groups, which included either no supplementation, pomegranate juice, or exercise (107853). The validity of this meta-analysis is limited due to the population heterogeneity and variety of orange juice formulations and controls utilized. Some clinical studies have also evaluated sweet orange juice for improving cardiovascular risk factors in overweight and obese adults. Although some research has shown benefit, not all research agrees (110046,110047). A meta-analysis of randomized clinical trials in adults with overweight or obesity shows that drinking sweet orange juice 250-600 mL daily for 2-13 weeks modestly increases high-density lipoprotein cholesterol levels and decrease average systolic blood pressure by 1 mmHg when compared with control. However, drinking sweet orange juice does not affect other blood lipid levels, blood glucose levels, or markers of insulin resistance (110048). The validity of this study is limited by high heterogeneity and a small sample size. In addition, these improvements are unlikely to be considered clinically relevant. Sweet orange extract has also been studied in combination with other ingredients. Some clinical research in overweight adults shows that taking a specific combination product (Sinetrol, Fytexia) 450-700 mg twice daily containing sweet orange, blood orange, and grapefruit extracts for 12 weeks reduces body weight, BFP, and BMI when compared with placebo or baseline (95517,95518). It is unclear if these effects are due to sweet orange, other ingredients, or the combination.
Pre-procedural anxiety. It is unclear if inhaling sweet orange essential oil as aromatherapy reduces anxiety before surgeries or invasive procedures. Details: A small, low-quality study suggests that inhaling the scent from 3 drops of sweet orange essential oil applied to a cotton ball for 5 minutes modesty reduces anxiety and pain scores in patients undergoing needle insertion for hemodialysis when compared with performing a breathing exercise for 3 minutes (105455).
Prostate cancer. It is unclear if drinking sweet orange juice reduces prostate cancer risk. Details: Observational research has found that increasing dietary intake of sweet orange or sweet orange juice is not associated with a reduced risk of developing prostate cancer (15172).
Stress. It is unclear if inhaling sweet orange essential oil as aromatherapy is beneficial for stress. Details: Preliminary clinical research shows that using up to 10 drops of sweet orange essential oil as aromatherapy helps prevent some anxiety and tension associated with stressful tasks when compared with control (90505). More evidence is needed to rate sweet orange for these uses.

Interactions with Drugs view details

Below is general information about the interactions of the known ingredients contained in the product Kids Captain Concentrate Alcohol Free. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.

BACOPA

ANTICHOLINERGIC DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, concurrent use might decrease the effectiveness of both agents.

Details

Bacopa seems to inhibit acetylcholinesterase and might increase acetylcholine levels, which could counteract the effects of anticholinergic drugs (17946). Similarly, anticholinergic drugs might counteract the cholinergic effects of bacopa.

CEVIMELINE (Evoxac)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, bacopa might increase the effects and adverse effects of cevimeline.

Details

In one case, a 58-year-old female taking cevimeline long-term for Sjogren syndrome experienced hyperhidrosis, malaise, nausea, and tachycardia shortly after taking a single dose of bacopa. Symptoms resolved after two days. Cevimeline is metabolized by cytochrome P450 (CYP) 2D6 and CYP3A4, and researchers theorize that bacopa may have inhibited these isoenzymes (109627). However, it is unclear if bacopa causes clinically significant inhibition of either CYP2D6 or CYP3A4.

CHOLINERGIC DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, concurrent use of bacopa with other cholinergic drugs might have additive effects.

Details

Bacopa seems to inhibit acetylcholinesterase and might increase acetylcholine levels (17946). Theoretically, this could result in additive cholinergic effects when used with cholinergic drugs.

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, bacopa might increase the levels and adverse effects of CYP1A2 substrates.

Details

Research on the effects of bacopa extracts on CYP1A2 enzymes is conflicting. Some in vitro evidence shows that bacopa extract can moderately and non-competitively inhibit CYP1A2, while other in vitro evidence suggests that any effect is unlikely to be clinically significant (97269,97606).

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, bacopa might increase the levels and adverse effects of CYP3A4 substrates.

Details

Research on the effects of bacopa extracts on CYP3A4 enzymes is conflicting. Some in vitro evidence suggests that bacopa extract can moderately and competitively inhibit CYP3A4, while other in vitro evidence suggests that any effect is unlikely to be clinically significant (97269,97606).

THYROID HORMONE

Interaction Rating = Minor Be watchful with this combination.

Severity = Mild • Occurrence = Possible • Level of Evidence = D

Theoretically, bacopa might have additive effects when used with thyroid hormone.

Details

Animal research suggests that bacopa increases thyroxine (T4) levels in mice by about 40% (33286).

DANDELION

ANTICOAGULANT/ANTIPLATELET DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, taking dandelion root along with anticoagulant or antiplatelet drugs might increase the risk of bruising and bleeding.

Details

In vitro research suggests that dandelion root inhibits platelet aggregation (18291).

ANTIDIABETES DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, dandelion might increase the risk for hypoglycemia when used with antidiabetes drugs.

Details

Laboratory research suggests that dandelion extract may have moderate alpha-glucosidase inhibitor activity and might also increase insulin secretion (13474,90926). Also, in a case report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemia 2 weeks after beginning to eat salads containing dandelion (46960).

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, dandelion might increase levels of drugs metabolized by CYP1A2.

Details

Laboratory research suggests that dandelion might inhibit CYP1A2 (12734). So far, this interaction has not been reported in humans. However, until more is known, watch for an increase in the levels of drugs metabolized by CYP1A2 in patients taking dandelion.

GLUCURONIDATED DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, dandelion might increase the clearance of drugs that are UDP-glucuronosyltransferase substrates.

Details

There is some preliminary evidence that dandelion might induce UDP-glucuronosyltransferase, a phase II enzyme (12734).

LITHIUM

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = D

Theoretically, through diuretic effects, dandelion might reduce excretion and increase levels of lithium.

Details

Animal research suggests that dandelion has diuretic properties (13475). As diuretics can increase serum lithium levels, the dose of lithium might need to be decreased when taken with dandelion.

POTASSIUM-SPARING DIURETICS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, dandelion might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.

Details

Dandelion contains significant amounts of potassium (13465).

QUINOLONE ANTIBIOTICS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, dandelion might lower fluoroquinolone levels.

Details

Animal research shows that dandelion reduces absorption of ciprofloxacin and can lower levels by 73% (13477). However, this effect has not been reported in humans.

LAVENDER

CNS DEPRESSANTS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Unlikely • Level of Evidence = D

Theoretically, lavender might potentiate the therapeutic effects and adverse effects of CNS depressants.

Details

Laboratory research suggests that lavender has sedative effects (7). However, clinical studies in patients taking oral lavender oil (Silexan) 160 mg for 10 weeks or taking lavender flower powder 1 gram daily for 2 months have not reported side effects of drowsiness, sedation, or sleepiness (97256,103061). There is still some concern that higher doses or different preparations of lavender might have additive effects with CNS depressant medications.

LEMON BALM

CNS DEPRESSANTS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = B

Theoretically, concomitant use of lemon balm might have additive effects with CNS depressant drugs.

Details

Lemon balm seems to have CNS depressant activity in animals and in humans (9994,19725).

THYROID HORMONE

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, lemon balm might interfere with thyroid hormone replacement therapy.

Details

In vitro, constituents of lemon balm extract bind to thyroid stimulating hormone (TSH), preventing TSH receptor-binding and leading to the inhibition of TSH-stimulated adenylate cyclase activity (19727,19728). In animals, lemon balm extract has been shown to decrease levels of circulating TSH and inhibit thyroid secretion (19726).

OATS (Oat)

ANTIDIABETES DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, oats may have additive effects with antidiabetic agents and might increase the risk of hypoglycemia.

Details

Consuming oats can decrease blood glucose in patients with diabetes (4980,4982,6266,103345). In those who require insulin, taking oats 100 grams daily for 2 days reduces the insulin dose required to achieve metabolic control (103336).

INSULIN

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = B

Concomitant use of oats and insulin might increase the risk of hypoglycemia.

Details

In patients with insulin-dependent type 2 diabetes, taking oats 100 grams daily for 2 days reduces the insulin dose required to achieve metabolic control (103336).

CNS DEPRESSANTS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Concomitant use of passion flower with sedative drugs might cause additive effects and side effects.

Details

Research in animals and humans shows that passion flower has sedative effects which can be additive when used with sedative medications like lorazepam (8007,19235,19236,19429,68309,104206).

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Interaction Rating = Minor Be watchful with this combination.

Severity = Insignificant • Occurrence = Possible • Level of Evidence = D

Theoretically, passion flower might decrease the effects of CYP3A4 substrates.

Details

In vitro research suggests that passion flower can induce CYP3A4 enzymes, albeit to a much lower degree than rifampin, a known CYP3A4 inducer (110704).

ORGANIC ANION-TRANSPORTING POLYPEPTIDE SUBSTRATES (OATP)

Interaction Rating = Minor Be watchful with this combination.

Severity = Mild • Occurrence = Possible • Level of Evidence = D

Theoretically, passion flower might reduce the bioavailability of OATP2B1 and OATP1A2 substrates.

Details

In vitro research shows that the passion flower constituents apigenin and vitexin inhibit OATP2B1 and OATP1A2. This inhibition may be dose-dependent. One specific high-flavonoid passion flower extract (Valverde) seems to inhibit OATP2B1 and OATP1A2, while another extract with a lower flavonoid concentration (Arkocaps) shows less potent inhibition (105095). OATPs are responsible for the uptake of drugs and other compounds into the body; however, the specific activities of OATP2B1 and OATP1A2 are not well characterized.

CELIPROLOL (Celicard)

Interaction Rating = Major Do not take this combination.

Severity = Moderate • Occurrence = Likely • Level of Evidence = B

Consuming sweet orange with celiprolol can decrease oral absorption of celiprolol.

Details

A pharmacokinetic study in healthy volunteers shows that celiprolol levels, after a single dose of 100 mg, are decreased by up to 90% in people who drink sweet orange juice 200 mL three times daily. It's not known if lower consumption of sweet orange juice will have the same effect. Theoretically, this occurs due to short-term inhibition of organic anion transporting polypeptide (OATP) (12115,17603,17604). Recommend separating drug administration and consumption of sweet orange by at least 4 hours (17603,17604).

FEXOFENADINE (Allegra)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Mild • Occurrence = Likely • Level of Evidence = B

Consuming sweet orange juice with fexofenadine can decrease oral absorption of fexofenadine.

Details

Clinical research shows that coadministration of sweet orange juice 1200 mL decreases bioavailability of fexofenadine by about 72% (7046,17604). In an animal model, sweet orange juice decreased bioavailability of fexofenadine by 31% (17605). Fexofenadine manufacturer data indicates that concomitant administration of sweet orange juice and fexofenadine results in larger wheal and flare sizes in research models. This suggests that sweet orange reduces the clinical response to fexofenadine (17603). Theoretically, this occurs due to short-term inhibition of organic anion transporting polypeptide (OATP) (7046). Recommend separating drug administration and consumption of sweet orange by at least 4 hours (17603,17604).

IVERMECTIN (Stromectol, others)

Interaction Rating = Major Do not take this combination.

Severity = Moderate • Occurrence = Likely • Level of Evidence = B

Consuming sweet orange juice with ivermectin can decrease the oral absorption of ivermectin.

Details

A pharmacokinetic study in healthy volunteers shows that taking ivermectin orally with sweet orange juice 750 mL over 4 hours reduces the bioavailability of ivermectin. This effect does not seem to be related to effects on P-glycoprotein. The effect on ivermectin is more pronounced in males compared to females (12154).

ORGANIC ANION-TRANSPORTING POLYPEPTIDE SUBSTRATES (OATP)

Interaction Rating = Major Do not take this combination.

Severity = Moderate • Occurrence = Likely • Level of Evidence = B

Consuming sweet orange juice can decrease oral absorption of OATP substrates. Separate administration by at least 4 hours.

Details

Clinical research shows that consuming sweet orange juice inhibits OATP, which reduces bioavailability of oral drugs that are substrates of OATP (17603,17604). For example, sweet orange juice decreases bioavailability of fexofenadine, a substrate of OATP, by about 72% and of celiprolol, another OATP substrate, by up to 90% (7046,12115). Since sweet orange juice seems to affect OATP for a short time, recommend separating drug administration and consumption of sweet orange juice by at least 4 hours (17603,17604).

P-GLYCOPROTEIN SUBSTRATES

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = B

Sweet orange juice seems to modulate P-glycoprotein (P-gp), which might affect the blood levels of P-gp substrates.

Details

Animal and in vitro research suggest that orange juice extract inhibits drug efflux by P-gp, increasing absorption and levels of P-gp substrates (12116,15327). In contrast, pharmacokinetic research in humans shows that drinking large amounts of sweet orange juice decreases absorption and levels of the P-gp substrate celiprolol. This suggests that orange juice actually induces drug efflux by P-gp or affects drug levels by another mechanism such as inhibiting the gut drug transporter called organic anion transporting polypeptide (OATP) (7046,12115). Until more is known, sweet orange juice should be used cautiously in people taking P-gp substrates.

PRAVASTATIN (Pravachol)

Interaction Rating = Major Do not take this combination.

Severity = Moderate • Occurrence = Likely • Level of Evidence = B

Consuming sweet orange juice with pravastatin can increase the absorption of pravastatin.

Details

A small pharmacokinetic study in healthy volunteers shows that consuming sweet orange juice 800 mL over 3 hours, including before, during, and after taking pravastatin 10 mg, increases pravastatin levels by about 149%, without affecting pravastatin elimination. Theoretically this effect might be due to modulation of organic anion transporting polypeptides (OATPs) by sweet orange juice (14348). Sweet orange juice does not seem to affect simvastatin levels, but it is not known if sweet orange affects any of the other statins.

QUINOLONE ANTIBIOTICS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Calcium-fortified sweet orange juice might reduce quinolone absorption.

Details

Calcium binds to quinolones in the gut. Theoretically, the calcium in certain fortified orange juices can also bind to quinolone antibiotics and reduce their absorption and levels (4412,10339,13714,21638,38570).

BACOPA

General ...Orally, bacopa is generally well tolerated.
Most Common Adverse Effects:
Orally: Abdominal cramps, diarrhea, dry mouth, headache, nausea.

Cardiovascular ...Orally, bacopa has been reported to cause palpitations (10058).

Gastrointestinal ...Orally, bacopa has been reported to cause abdominal cramps, abdominal pain, bloating, decreased appetite, diarrhea, dry mouth, excessive thirst, flatulence, indigestion, nausea, and increased stool frequency. Rates of adverse gastrointestinal events have ranged from 12% to 30% (10058,17946,33295,97605,109623,111520).

Musculoskeletal ...Orally, bacopa has been reported to cause arthralgia, muscle fatigue, and myopathy (10058,109623,111522). In one case, a 21-year-old male experienced progressive proximal weakness, muscle atrophy, weight loss, dark urine, and elevated serum markers of myopathy, with muscle biopsy showing immune-mediated necrotizing myopathy, after taking a supplement containing bacopa for 5 years (111522).

Neurologic/CNS ...Orally, bacopa has been reported to cause drowsiness, headache, insomnia, and vivid dreams (10058,10059,17946,109623).

Other ...Orally, bacopa has been reported to cause flu like symptoms and fatigue (10058,97605,111520).

DANDELION

General ...Orally, dandelion seems to be well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, heartburn, and stomach discomfort.
Topically: Dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis in sensitive individuals.

Cardiovascular ...In one report, a 39-year-old obese woman developed palpitations and syncope after taking a weight loss supplement containing a combination of dandelion, bladderwrack, and boldo for 3 weeks. The patient was found to have prolonged QT-interval on ECG and frequent episodes of sustained polymorphic ventricular tachycardia (14321). It is not clear whether dandelion, another ingredient, or the combination of ingredients is responsible for this adverse effect. The product was not analyzed to determine the presence of any potential toxic contaminants.

Dermatologic ...Topically, dandelion can cause contact dermatitis and erythema multiforme in sensitive individuals. Dandelion can cause an allergic reaction in individuals sensitive to the Asteraceae/Compositae family (13478,13481,42893,46945,46977). Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs.

Endocrine ...In one report, a 56-year-old man with renal impairment developed hyperoxalaemia and peripheral gangrene after ingesting large amounts of dandelion tea (10 to 15 cups daily for 6 months). The adverse effect was attributed to the high oxalate content of dandelion tea (258 mcmol/L) and reduced renal oxalate clearance caused by renal impairment (90639). In another report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemic symptoms 2 weeks after beginning to eat salads containing dandelion (46960). The hypoglycemic effect was attributed to the potential alpha-glucosidase inhibitory activity of dandelion.

Gastrointestinal ...Gastrointestinal symptoms, including stomach discomfort, diarrhea, and heartburn, have been reported following oral use of dandelion (19146,36931). A case of intestinal blockage has been reported for a patient who ingested a large amount of dandelion greens three weeks after undergoing a stomach operation (46981). Also, a case of hemorrhagic cystitis has been reported for a 33-year-old woman who took a specific herbal product (Slim-Kombu, Balestra and Mech, Vicenza, Italy) containing 20 herbal extracts, including dandelion extract. Symptoms resolved after the patient discontinued using the product, and symptoms resumed when the patient began taking the supplement again four months later. While various ingredients in the supplement may have contributed to the symptoms, it is possible that dandelion extract may have contributed to the effect due to its diurectic, laxative, cholagogue, and antirheumatic properties (46959).

Other ...Orally, products containing dandelion pollen can cause allergic reactions, including anaphylaxis (13479,13480). Also, rhinoconjunctivitis and asthma have been reported after handling products such as bird feed containing dandelion and other herbs, with reported positive skin tests for dandelion hypersensitivity (46948). Dandelion pollen may cause pollinosis, such as allergic rhinitis and conjunctivitis (18065,46951,46964,46966,46972).

LAVENDER

General ...Orally, lavender is well tolerated in food amounts and seems to be well tolerated in larger amounts. Topically, lavender oil seems to be well tolerated.
Most Common Adverse Effects:
Orally: Breath odor, constipation, diarrhea, dyspepsia, eructation, headache, and nausea.
Topically: Allergic contact dermatitis (with lavender oil).
Serious Adverse Effects (Rare):
Topically: Cases of gynecomastia have been reported in prepubertal males using lavender oil.

Cardiovascular ...Orally, a specific lavender oil ingredient (Silexan) has been associated with palpitations (103061).

Endocrine ...Topical products containing lavender oil alone, including a product referred to as agua de violetas, or in combination with tea tree oil have been linked to at least six cases of gynecomastia when used in prepubertal males. In each case, gynecomastia resolved when the lavender oil products were discontinued. It is thought that the estrogenic and antiandrogenic activity of lavender oil and tea tree oil resulted in gynecomastia in these cases (15254,95643).

Gastrointestinal ...Orally, lavender oil, including a specific lavender oil ingredient KG), may cause gastrointestinal disturbance, including dyspepsia, diarrhea, breath odor, eructation, and nausea (58077,58080,58098,93004,103061). Tincture of lavender has been linked to cases of constipation and increased appetite; however, it is unknown if this occurred at a greater rate than with placebo (9792).

Immunologic ...Topically, use of lavender oil, such as in personal care products, might cause allergic contact dermatitis in some patients (6,101728). There have been numerous case reports of allergic contact dermatitis and eczema linked to lavender oil exposure from shampoos, lotions, fragrances, or direct application of oil to pillows (10031,58043,58109,58120,101728).

Neurologic/CNS ...Orally, lavender flower powder, tincture of lavender containing 50% alcohol, and a specific lavender oil ingredient (Silexan) have been linked to headache (9792,103061,109860). Headache has also been reported rarely following lavender oil aromatherapy (109860).

Pulmonary/Respiratory ...In one case report, a 34-year-old Japanese female presented with complaints of dyspnea, cough, and fever 2 weeks after initiating lavender essential oil therapy via humidifier. The patient had an oxygen saturation of 88% and was diagnosed with acute eosinophilic pneumonia. Symptoms improved after a course of corticosteroids and discontinuation of aromatherapy (109979).

LEMON BALM

General ...Orally, lemon balm seems to be well tolerated in food amounts and larger, medicinal amounts. Topically, lemon balm seems to be well tolerated.
Serious Adverse Effects (Rare):
Orally: Wheezing has been rarely reported.

Cardiovascular ...Orally, a case of transient complete atrioventricular block and QT prolongation is reported in a 25-year-old female following the post-workout use of a specific product (Muscle Eze Advanced) containing lemon balm and several other ingredients. Symptoms of fatigue and lightheadedness started 1 week into use of the product. Product discontinuation led to restoration of normal sinus rhythm within 24 hours and normalization of the electrocardiogram within 2 weeks (112556). It is unclear whether this occurrence is due to lemon balm, other ingredients, or the combination.

Dermatologic ...Topically, lemon balm 1% cream applied 5 times daily to cold sores has been associated with two cases of irritation and one case of cold sore exacerbation. However, these effects do not appear to occur more often with lemon balm than with placebo (790).

Gastrointestinal ...Orally, lemon balm might increase appetite in some patients (91732,104433). Nausea, vomiting, and abdominal pain have been reported rarely and do not seem to occur more often than in patients taking placebo (9993).

Neurologic/CNS ...Orally, lemon balm has been reported to cause dizziness and sedation; however, it does not seem to occur more often with lemon balm than placebo (9993,104433). Additionally, other clinical research shows that using lemon balm in conjunction with alcohol does not affect reaction time or influence cognitive performance (19427,19723).

Pulmonary/Respiratory ...Orally, lemon balm has been associated with rare cases of wheezing (9993).

OATS (Oat)

General ...Orally, oats are well tolerated.
Most Common Adverse Effects:
Orally: Abdominal distension, bloating, flatulence, and unpleasant taste.
Topically: Burning, contact dermatitis, itching, and redness.

Dermatologic ...Topically, oat-containing preparations can cause contact dermatitis (12515). Redness, burning, and itchiness have also been reported (103340).

Gastrointestinal ...When consumed orally, oats provide fiber. Increasing fiber in the diet can cause flatulence, bloating, abdominal distention, and unpleasant taste. To minimize side effects, doses should be slowly titrated to the desired level. These adverse effects usually subside with continued use (12514).
In patients who have difficulty chewing food, or those with conditions that decrease small bowel motility, oat bran may cause bezoars (concretions) and intestinal obstruction. Oats and oat bran are unlikely to cause obstruction without other causative factors (4979,4985).

General ...Orally, passion flower is well tolerated.
Most Common Adverse Effects:
Orally: Confusion, dizziness, hypersensitivity, and sedation.

Cardiovascular ...There is a case report involving a 34-year-old female who was hospitalized with severe nausea, vomiting, drowsiness, prolonged QT interval, and episodes of nonsustained ventricular tachycardia following use of passion flower extract tablets (Sedacalm, Bioplus Healthcare), 1500 mg on day 1 and 2000 mg on day 2 to relieve stress. All symptoms resolved within one week after passion flower was discontinued (6251).

Genitourinary ...The alkaloids harman and harmaline, which are sometimes found in small amounts in passion flower, have been reported to have uterine stimulant activity (4,11020,95037).

Hematologic ...Orally, passion flower has been reported to cause epistaxis in one clinical trial (95038). Vasculitis has also been reported with use of a specific herbal product (Relaxir) produced mainly from the fruits of passion flower (6).

Hepatic ...There is debate about whether passion flower contains cyanogenic glycosides. Several related Passiflora species do contain these constituents (3), including Passiflora edulis, which is associated with liver and pancreatic toxicity (7).

Immunologic ...An idiosyncratic hypersensitivity reaction characterized by urticaria and cutaneous vasculitis has been reported in a 77-year-old male with rheumatoid arthritis after taking a specific combination product that included passion flower extract (Naturest) (68308). It is unclear if these effects were caused by passion flower or other ingredients.
In clinical trials, passion flower has been reported to cause allergy symptoms including sinus irritation; however, the frequency of these events was statistically nonsignificant when compared to treatment with midazolam 15 mg (95038).

Musculoskeletal ...Orally, passion flower has been reported to cause muscle relaxation in a clinical trial (95038).

Neurologic/CNS ...Orally, sedation, dizziness, ataxia, and confusion have been reported in clinical trials. However, these events generally do not necessitate discontinuation (8007,15391,15392,95036,95038). Altered consciousness has been reported with use of a specific herbal product (Relaxir) produced mainly from the fruits of passion flower (6).

General ...Orally, sweet orange juice or fruit seem to be well tolerated. Large amounts of sweet orange peel may be unsafe, especially for children. When inhaled, sweet orange essential oil seems to be generally well tolerated.

Gastrointestinal ...There have been reports of intestinal colic in children following ingestion of large amounts of sweet orange peel (11).

Neurologic/CNS ...There have been reports of convulsions in children following ingestion of large amounts of sweet orange peel (11).
