CALIFORNIA POPPY

INSUFFICIENT RELIABLE EVIDENCE to RATE

Anxiety. Oral California poppy 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 anxiety disorder shows that taking a specific combination product (Sympathyl, Laboratoire Innotech International) containing California poppy, hawthorn, and magnesium improves clinician-rated and patient-rated symptoms of anxiety when compared with placebo (12583). It is not clear if this effect is due to California poppy, the other ingredients, or the combination.
Insomnia. Although there has been interest in using oral California poppy for insomnia, there is insufficient reliable information about the clinical effects of California poppy for this purpose.
Nocturnal enuresis. Although there has been interest in using oral California poppy for nocturnal enuresis in children, there is insufficient reliable information about the clinical effects of California poppy for this purpose. More evidence is needed to rate California poppy for these uses.

Influenza. Although there has been interest in using oral catnip for influenza, there is insufficient reliable information about the clinical effects of catnip for this purpose.
Insomnia. Although there has been interest in using oral catnip for insomnia, there is insufficient reliable information about the clinical effects of catnip for this purpose.
Migraine headache. Although there has been interest in using oral catnip for migraine headache, there is insufficient reliable information about the clinical effects of catnip for this purpose.
Mosquito repellent. It is unclear if oral catnip is beneficial as mosquito repellent. Details: Preliminary clinical research shows that applying a small amount of catnip oil or certain catnip constituents to the skin is more effective at repelling yellow fever mosquitoes when compared with ethanol. However, catnip oil and catnip constituents appear to be less effective than the commercial insect repellents SS220 and DEET (40200).
Osteoarthritis. Although there has been interest in using topical catnip for osteoarthritis, there is insufficient reliable information about the clinical effects of catnip for this purpose.
Tension headache. Although there has been interest in using oral catnip for tension headache, there is insufficient reliable information about the clinical effects of catnip for this purpose.
Upper respiratory tract infection (URTI). Although there has been interest in using oral catnip for URTI, there is insufficient reliable information about the clinical effects of catnip for this purpose.
Urticaria. Although there has been interest in using oral catnip for urticaria, there is insufficient reliable information about the clinical effects of catnip for this purpose. More evidence is needed to rate catnip for these uses.

LAVENDER

POSSIBLY EFFECTIVE

Anxiety. Orally, lavender 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: Guidelines from The World Federation of Societies of Biological Psychiatry (WFSBP) and Canadian Network for Mood and Anxiety Treatments (CANMAT) Taskforce state that lavender essential oil at doses of 80-160 mg daily or dried lavender flower at doses of 500-1500 mg twice daily is provisionally recommended for monotherapy or adjunctive use in the treatment of generalized anxiety disorder. Essential oil capsules and standardized dried flower formulations are preferred over tea preparations (110318). Additionally, guidelines from the American Society of Clinical Oncology and the Society for Integrative Oncology provide a weak recommendation for the use of lavender essential oil inhalation in people with cancer procedure-related anxiety. The recommendation is based on low-quality evidence (114626,114642). Most meta-analyses and clinical trials in patients with subthreshold anxiety, mixed anxiety and depressive disorder, generalized anxiety disorder, and 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 objective and subjective measures of anxiety and increases response rates and complete remission rates when compared with placebo. However, heterogeneity and small sample sizes limit the validity of these findings (58077,58080,58098,95640,97257,103061,103069,112255,114628). Subgroup analyses of 5 clinical studies suggest that Silexan is more effective in older adults with higher somatic symptom burden and those with anxiety-related difficulties in concentration and poor memory at baseline (112255). Additionally, an individual patient-level analysis of 5 clinical studies shows that while Silexan is beneficial in mild to severe anxiety, treatment effects may be more pronounced in those with greater severity at baseline (114628). Limited research has compared Silexan to some conventional prescription medications. One clinical study shows that taking Silexan 80 mg daily for 6 weeks improves anxiety and quality of sleep similarly to low-dose lorazepam 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 similarly 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. Lavender aromatherapy has also been evaluated. Meta-analyses of clinical trials in adults 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). A meta-analysis of 5 clinical studies in adults undergoing hemodialysis shows that aromatherapy with 2% to 100% lavender oil reduces anxiety when compared with control groups receiving no intervention (114625). 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 adults. Clinical research also shows that lavender oil aromatherapy may improve symptoms of depression. Details: Guidelines from The World Federation of Societies of Biological Psychiatry (WFSBP) and Canadian Network for Mood and Anxiety Treatments (CANMAT) Taskforce state that lavender essential oil at doses of 80-160 mg daily or dried lavender flower at doses of 500-1500 mg twice daily is weakly recommended for monotherapy or adjunctive use in the treatment of major depressive disorder (MDD) (110318). Essential oil capsules and standardized dried flower formulations are preferred over tea preparations. 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 adults, or in adults with MDD, 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). Some research has compared lavender with traditional antidepressants. A large clinical study in adults with mild to moderate MDD shows that taking Silexan 80 mg daily for 8 weeks reduces symptoms of depression as measured on the Montgomery-Asberg Depression Rating Scale (MADRS), and also improves functional impairment, when compared with placebo. These improvements were similar to those seen in a control group taking sertraline 50 mg daily (114631). Conversely, a small clinical study in adults with mild to moderate MDD shows that drinking 60 drops per day of a 1:5 tincture of lavender appears to be slightly less effective than imipramine 100 mg daily; however, lavender might have some additive antidepressant effects when used in combination with imipramine (9792). The validity of these findings is limited by the small study size. Lavender has also been taken in combination with other products. A small clinical study in adults 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 populations, and no studies were specific to adults with MDD. Lavender aromatherapy was compared with no intervention, routine care, other aromatherapy oils, or distilled water (109860). A small clinical study in adults with post-stroke depression shows that lavender aromatherapy via microcapsules placed inside of a nonwoven bag under the pillow each night for 4 weeks reduces symptoms of depression when compared with control (114627). 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.
Pain (acute). Most clinical research suggests that lavender aromatherapy modestly reduces acute pain from needle insertion or other procedures in infants and adults. The benefit of oral lavender or lavender aromatherapy for other forms of acute pain is unclear. Details: Lavender oil aromatherapy has shown modest benefit for limiting acute pain in adults undergoing a variety of medical procedures. A meta-analysis of 6 small clinical studies shows that lavender aromatherapy, inhaled or as topical application, reduces the severity of pain experienced with arteriovenous fistula catheter insertion for hemodialysis when compared with control (114632). A clinical study in adults with diabetes shows that topical lavender oil sprayed 3 times on the arm five minutes before insulin injection reduces injection site pain when compared with placebo (112254). Additionally, a clinical study in adults undergoing surgical drain removal shows that administering lavender aromatherapy as 2 drops of lavender oil in the oxygen mask reduces pain similarly to a cold compress and to a greater extent than oxygen alone or a control group receiving no intervention (114633). Clinical research also shows that inhaling 10% lavender oil from a heat lamp for 10-15 minutes prior to gynecological exams reduces pain experienced during the exam when compared with no treatment (95639). However, lavender aromatherapy may not reduce pain related to extracorporeal shockwave lithotripsy (ESWL). A clinical study in adults with kidney stones shows that inhaling 4 drops of diffused lavender oil does not reduce pain or the use of self-administered opioids after ESWL when compared with standard care. These results were unchanged when lavender aromatherapy was combined with music (112258). The validity of these findings is limited by a lack of blinding and the high variability in kidney stone size between groups. Lavender oil aromatherapy also seems to modestly reduce pain in infants undergoing various medical procedures. One clinical study in term infants shows that aromatherapy with lavender oil 0.5% for one minute before vaccination modestly reduces pain and decreases crying time by about 20 seconds when compared with sweet almond oil (109869). Another 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 to a similar extent as 2 mL of 30% glucose solution and to a greater extent than no intervention (103066). A small clinical study in preterm 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 reduces pain scores when compared with exposure to an unscented cotton ball (104442). Another small clinical study in preterm infants shows that placing cotton soaked with lavender oil in front of the infant's nose for 5 minutes before and 2 minutes after venipuncture reduces pain intensity during and after venipuncture to a similar extent as cotton soaked in breastmilk but to a greater extent than cotton soaked with distilled water (114638). A small clinical study also shows that applying a gauze pad containing one drop of lavender oil under the nose, starting 2 minutes before 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 for this purpose (109810).

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).

INSUFFICIENT RELIABLE EVIDENCE to RATE

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. Two clinical studies suggest that lavender oil, applied topically during massage of the belly or inhaled as aromatherapy, might modestly reduce duration of crying in infants with colic. 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. Another moderate-sized clinical study in infants 4-8 weeks old with colic shows that inhaling lavender oil as aromatherapy for 4-6 hours daily for 7 days reduces the duration of night crying when compared with placebo (112260).
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 improving the symptoms of mild to moderate COVID-19. Details: A small clinical trial in adults 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 participants 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). A clinical study in adults with mild to moderate respiratory symptoms, suspected by not confirmed to be caused by COVID-19, shows that taking lavender syrup 9 mL twice daily for 3 weeks with standard care reduces severity of cough and anosmia, but not anxiety or any other respiratory symptoms, when compared with standard care alone (114635). The interpretation of these results is limited by the lack of a placebo group and the lack of confirmation of COVID-19 infection.
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, but not all, 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 (95642,98524,109867). A meta-analysis of 5 clinical studies in patients undergoing hemodialysis shows that aromatherapy with 5% to 100% lavender essential oil reduces fatigue when compared with control groups inhaling almond oil or receiving no intervention (114625). 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. Lavender has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in adults with mild hypertension shows that aromatherapy with lavender oil 0.3% and ylang ylang oil 0.7%, provided via a fabric sticker placed on participant shirt collars, modestly reduces systolic blood pressure after 3 days of use and heart rate after 14 days of use when compared with control stickers containing no essential oils (114641).
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 small 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. Additionally, a small clinical study in adults with post-stroke depression shows that lavender aromatherapy via microcapsules placed inside of a nonwoven bag under the pillow each night for 4 weeks improves sleep quality, latency, and duration when compared with control (114627). 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. Small studies suggest that lavender oil aromatherapy may help to modestly reduce pain during childbirth. Details: A meta-analysis of clinical trials 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 included studies were 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 either lavender aromatherapy or oral lavender reduce menopausal symptoms such as hot flashes. 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 flashes 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). Oral lavender has also been evaluated for improving menopausal symptoms. A small clinical study in postmenopausal adults shows that taking lavender essential oil 80 mg daily by mouth for 2 months does not improve overall menopausal symptom scores when compared with placebo. Although it modestly improved symptoms of sexual dysfunction, it did not improve other vasomotor, physical, or psychological menopausal symptoms when compared with placebo (114629).
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 or lavender aromatherapy is beneficial for reducing fatigue in adults with multiple sclerosis (MS). Details: A small clinical trial in adults 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). Another small clinical study in adults with MS living in Turkey shows that lavender aromatherapy, provided as 3 drops of lavender oil on cotton pads placed 15-20 cm from the bed pillow nightly for 30 days, reduces fatigue severity and improves sleep quality when compared with no intervention (114630).
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).
Perioperative anxiety. It is unclear if lavender aromatherapy is beneficial for perioperative anxiety. Details: A large clinical study in adults shows that inhaling lavender 2% before, during, and after dental procedures reduces dental pain intensity and perioperative dental anxiety when compared with control. Inhaled lavender seems to have the greatest effect on perioperative anxiety when used in the waiting room (112250). Conversely, a clinical study in adults with kidney stones undergoing extracorporeal shockwave lithotripsy (ESWL) shows that inhaling 4 drops of diffused lavender oil does not reduce anxiety when compared with standard opioid analgesia. These results were unchanged when lavender aromatherapy was combined with music (112258). The validity of these effects is limited by a lack of blinding and the high variability in kidney stone size between groups. Lavender has also been evaluated in combination with other ingredients. A clinical study in adults undergoing port catheter placement under modified anesthesia shows that preoperative and intraoperative placement of an aromatherapy patch containing lavender and peppermint essential oils (Elequil Aromatabs, Beekley Corporation) near the head does not reduce benzodiazepine or opioid requirements or time to discharge when compared with a placebo patch (114623). It is unclear if the use of an oxygen mask during the procedure resulted in inadequate exposure to the aromatherapy oils.
Polycystic ovary syndrome (PCOS). It is unclear if lavender is beneficial for PCOS. Details: A small clinical study in adults with PCOS between the ages of 18-45 who had not received any prior treatment for the condition shows that taking lavender 250 mg twice daily for 90 days increases serum progesterone levels and reduces menstrual cycle length similarly to metformin 500 mg three times daily (114634).
Postdural puncture headache. It is unclear if lavender aromatherapy improves postdural puncture headache severity. Details: A small clinical study in adults 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).
Postherpetic neuralgia. It is unclear if lavender aromatherapy is beneficial for alleviating pain in postherpetic neuralgia. Details: A small clinical study in adults with postherpetic neuralgia shows that aromatherapy with either lavender oil 1% or oils containing two of its major constituents (linalool 1% or linalyl acetate 1%), placed on gauze and then inhaled with natural breathing for 5 minutes, reduces the intensity and severity of pain when compared with almond oil control (114624). The validity of this finding is limited by the short-term nature of the study; any benefit beyond 5 minutes was not evaluated.
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). A specific combination patch providing both lavender and peppermint essential oils (Elequil Aromatabs, Beekley Corporation) has also been evaluated, with conflicting findings. A clinical study in adults undergoing port catheter placement under modified anesthesia shows that preoperative and intraoperative placement of this patch near the head does not reduce antiemetic requirements, the proportion of patients requiring antiemetics, or average PONV scores when compared with a placebo patch (114623). It is unclear if the use of an oxygen mask during the procedure resulted in inadequate exposure to the essential oils. Conversely, a small clinical study in patients with anxiety prior to primary unilateral total hip arthroplasty shows that placement of this patch on the gown at least 1 hour before surgery, with re-application every 12 hours postoperatively for 2 days, reduces PONV on postoperative day 2 when compared with a placebo patch (114622). It is unclear if this effect is due to lavender, peppermint, or the combination.
Postoperative pain. The evidence for the use of lavender aromatherapy for pain after various types of surgical procedures is conflicting. Details: Some small clinical studies 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 modestly reduces postoperative pain when compared with control (58093,101724). A small clinical study in adults 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). 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). Additionally, a clinical study in adults hospitalized after abdominal surgery shows that a lavender oil-infused warm water foot bath for 20 minutes each night for 3 nights after surgery does not reduce postoperative pain when compared with a standard warm water foot bath (114637). Likewise, a clinical study in adults hospitalized after total knee or hip arthroplasty shows that lavender aromatherapy administered via inhalers and used as needed does not reduce pain or analgesic use when compared with control (114639). Lavender oil aromatherapy has also been evaluated in children. 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 acetaminophen use when compared with control (90513). A specific combination patch providing both lavender and peppermint essential oils (Elequil Aromatabs, Beekley Corporation) has also been evaluated, with conflicting findings. A clinical study in adults undergoing port catheter placement under modified anesthesia shows that preoperative and intraoperative placement of the patch near the head does not reduce time to readiness for discharge, opioid requirements, or pain intensity scores when compared with a placebo patch (114623). It is unclear if the use of an oxygen mask during the procedure resulted in inadequate exposure to the essential oils. Conversely, a small clinical study in patients with anxiety prior to primary unilateral total hip arthroplasty shows that placing the patch on the gown at least 1 hour before surgery, with re-application every 12 hours postoperatively for 2 days, reduces opioid use on postoperative day 2, as well as pain scores and acetaminophen use on postoperative day 7, when compared with a placebo patch (114622). It is unclear if any effect is due to lavender, peppermint, or the combination.
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). Similarly, a meta-analysis of 19 small to moderate-sized clinical studies in adults undergoing various types of surgical procedures shows that lavender aromatherapy modestly reduces preoperative anxiety when compared with routine care or placebo (114636). However, most of the studies included in these meta-analyses 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 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.
Pruritus. Topical lavender has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in older females with pruritus shows that aromatherapy massage utilizing a 4:1:1 mixture of lavender, Roman chamomile, and sandalwood oils diluted to 1.5% in sweet almond oil, three times weekly for 1 month, modestly improves pruritus and reduces pruritus-related stress when compared with sandalwood oil alone. However, it does not improve skin pH or level of hydration (112365). It is unclear if these findings are due to lavender, other ingredients, or the combination.
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 small clinical studies suggest that lavender oil aromatherapy massage may be beneficial for RLS in patients undergoing hemodialysis. Its benefits in other patient populations are unclear. Details: A meta-analysis of 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 (95638,103064,109865,114632). 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 10-45 minutes during hemodialysis sessions for 3-4 weeks (95638,103064,109859,109865).
Stress. Some clinical studies suggest that inhaling lavender oil as aromatherapy may reduce stress. However, overall research is conflicting. 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). In contrast, a clinical study in pharmacy students shows that 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, when compared with inhaling an odorless oil, although both were more effective than no intervention (101723). Lavender oil aromatherapy has shown conflicting results when evaluated for reducing stress in healthcare professionals. A small study in hospital nurses with work-related stress shows that inhaling lavender oil as aromatherapy for 2 hours daily for 4 weeks does not reduce job-related stress when compared with placebo or rose oil aromatherapy (112256). However, another small clinical study in healthcare professionals at an outpatient clinic shows that inhaling lavender oil through a diffuser during work shifts reduces work stress and increases job satisfaction when compared with placebo (112251).
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

POSSIBLY EFFECTIVE

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 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. Although studies have assessed oral lemon balm as monotherapy, its use in combination with other ingredients has also been explored. 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). Additionally, a single-center clinical study in Iranian adults with constipation-predominate irritable bowel syndrome (IBS-C) shows that taking a lemon balm, anise, and rose hip extract supplement twice daily for 4 weeks reduces anxiety and depression scores,on a patient-reported survey, when compared with placebo (115636). The validity of these results is limited by the lack of data regarding history or diagnosis of anxiety or depression. It is not clear if this effect is due to lemon balm, the other ingredients, or the combination.
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).

INSUFFICIENT RELIABLE EVIDENCE to RATE

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). Although studies have assessed oral lemon balm as monotherapy, its use in combination with other ingredients has also been explored. A single-center clinical study in Iranian adults with constipation-predominate irritable bowel syndrome (IBS-C) shows that taking a lemon balm, anise, and rose hip extract supplement twice daily for 4 weeks reduces anxiety and depression scores, on a patient-reported survey, when compared with placebo (115636). The validity of these results is limited by the lack of data regarding history or diagnosis of anxiety or depression. It is not clear if this effect is due to lemon balm, the other ingredients, or the combination.
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).
Dyslipidemia. It is unclear if oral lemon balm is beneficial in patients with dyslipidemia. Details: A meta-analysis of 5 small clinical studies in adults shows that oral lemon balm extract, leaf powder, or tea in doses ranging from 700-4000 mg daily for 8-24 weeks reduces low-density lipoprotein (LDL), total cholesterol (TC), and triglycerides (TG) when compared with placebo; however, the clinical significance of these findings is unclear (115638). The validity of these results is limited by the heterogenous methods between clinical trials, including population, dose, and study duration.
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. It is unclear if oral lemon balm is beneficial for insomnia. Details: A small, cross-over clinical study in Italy in adults with self-reported poor sleep quality shows that taking a specific lemon balm phytosome (Meloff, Pharmextracta SpA) 400 mg 30 minutes prior to bed for 2 weeks improves some, but not all, measures of sleep quality when compared with placebo . (115637). However, it is unclear if these improvements are clinically significant. Additionally, lemon balm has been evaluated in combination with other ingredients. 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.

PASSION FLOWER (Passionflower)

POSSIBLY EFFECTIVE

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.
Insomnia. Moderate-sized clinical studies suggest that oral passion flower may modestly improve total sleep time in patients with insomnia; however, its effects on sleep latency and maintenance are mixed. Details: A moderate-sized clinical study in adults in India with insomnia and stress shows that taking passion flower extract 600 mg daily at bedtime for 30 days increases total sleep time by about 30 minutes and reduces both the time to fall asleep and wake time after sleep onset by about 10 minutes when compared with placebo (114529). The validity of these findings is limited by lack of reporting on baseline use of medications or other substances which may impact sleep and exclusion of patients with severe insomnia. Another moderate-sized clinical study 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). Additionally, a 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).
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).

INSUFFICIENT RELIABLE EVIDENCE to RATE

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.
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. It is unclear if oral passion flower reduces stress. Details: A moderate-sized clinical study in adults in India with stress and insomnia shows that taking passion flower 600 mg daily at bedtime for 30 days modestly reduces stress when compared with placebo (114529). It is unclear how changes in stressors over the course of the study may have affected results. Additionally, 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.

PASSION FLOWER (Passionflower)

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.

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 (58077,58080,58098,93004,103061,114631). 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 (10031,58043,58109,58120,101728,112253). In one case series, only 4 out of 15 cases of allergic contact dermatitis due to lavender had positive patch tests for lavender. Oxidation products of lavender essential oils such as linalool, linalyl acetate, limonene, cineol, geraniol, eugenol, and isoeugenol may be more allergenic than un-oxidized lavender essential oil, which may result in a false negative patch test (112253). Orally, taking lavender was associated with itching and rash in one clinical study participant (114634).

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).

Renal ...In one case report, a 24-year-old male presented with shortness of breath, weakness, nausea, and decreased urine output following the intake of Spanish lavender tea twice daily for 5 days. After presenting to the hospital, the patient was diagnosed with acute kidney failure secondary to acute interstitial nephritis likely due to lavender consumption (112259).

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).

PASSION FLOWER (Passionflower)

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).
