• Allergic rhinitis (hay fever). Although there has been interest in using oral German chamomile for allergic rhinitis, there is insufficient reliable information about the clinical effects of German chamomile for this purpose.
• Anxiety. It is unclear if inhaled German chamomile essential oil, as aromatherapy, is beneficial in patients with anxiety. Details: A small clinical study in adults with gastrointestinal, neuroendocrine, and skin cancers receiving intravenous infusion therapy shows that inhaling German chamomile essential oil 3 times daily for 7 days does not reduce self-reported anxiety when compared with a control group (111379). German chamomile has also been studied in combination with other ingredients. A small, open-label study in critically ill children in the pediatric intensive care unit shows that aromatherapy massage with an essential oil 1% blend of lavender, German chamomile, and neroli in grapeseed oil reduces distress, anxiety, and heart rate when compared to baseline (111378). However, the validity of these findings is limited by a lack of blinding and control group. It is unclear if these effects are due to German chamomile, other ingredients, or the combination.
• Atopic dermatitis (eczema). It is unclear if topical German chamomile is beneficial in patients with atopic dermatitis. Details: Clinical research in patients with atopic dermatitis shows that applying a specific cream containing a 2% ethanolic extract of German chamomile flowers (Kamillosan, Asta Medica AG) up to three times daily for up to 4 weeks improves pruritus, erythema, and desquamation when compared with placebo or hydrocortisone 0.5% cream (19707).
• Attention deficit-hyperactivity disorder (ADHD). Although there has been interest in using oral German chamomile for ADHD, there is insufficient reliable information about the clinical effects of German chamomile for this purpose.
• Burning mouth syndrome. German chamomile has only been evaluated as a mouthwash in combination with flaxseed; its effect when used alone is unclear. Details: Preliminary clinical research in female patients with burning mouth syndrome shows that using a mouthwash containing German chamomile and flaxseed 3-4 times daily for 3 months decreases subjective burning and dry mouth symptoms, increases salivary flow rate, and decreases saliva viscosity when compared with baseline (104807). However, the validity of these results is limited by the lack of a control group and product standardization, as the mouthwash was prepared by each patient from ingredients they purchased.
• Cancer-related anorexia. It is unclear if inhaled German chamomile essential oil, as aromatherapy, is beneficial in patients with cancer-related anorexia. Details: A small clinical study in adults with gastrointestinal, neuroendocrine, and skin cancers receiving intravenous infusion therapy shows that inhaling German chamomile essential oil 3 times daily for 7 days does not increase self-reported appetite when compared with a control group (111379).
• Chemotherapy-induced fatigue. It is unclear if inhaled German chamomile essential oil, as aromatherapy, is beneficial in patients with chemotherapy-induced fatigue. Details: A small clinical study in adults with gastrointestinal, neuroendocrine, and skin cancers receiving intravenous infusion therapy shows that inhaling German chamomile essential oil 3 times daily for 7 days does not reduce self-reported fatigue when compared with a control group (111379).
• Chemotherapy-induced nausea and vomiting (CINV). It is unclear if inhaled German chamomile essential oil, as aromatherapy, is beneficial in patients with CINV. Details: A small clinical study in adults treated for gastrointestinal, neuroendocrine, and skin cancers with intravenous infusion therapy shows that inhaling German chamomile essential oil 3 times daily for 7 days does not improve self-reported nausea when compared with a control group. (111379).
• Colic. Oral German chamomile has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical studies in infants with colic show that two multi-ingredient products given orally twice daily for 1-4 weeks reduce crying times when compared with placebo or simethicone 60 mg twice daily. The products studied contained German chamomile 178 mg with fennel and lemon balm (ColiMil, Milte Italia SPA) and German chamomile 9 mg with lemon balm and Lactobacillus acidophilus (ColiMil Plus, Milte Italia SPA) (16735,96278). Other clinical research in infants shows that taking 150 mL of a specific herbal tea preparation (Calma-Bebi, Bonomelli) containing extracts of German chamomile, vervain, licorice, fennel, and lemon balm up to three times daily after each episode of colic for 7 days increases the percentage of infants with relief by 31% when compared with placebo, although there was no effect on the number of night awakenings (19715).
• Common cold. It is unclear if inhaling the steam from a solution of German chamomile in hot water is beneficial in patients with a common cold. Details: Preliminary clinical research shows that inhaling the steam from a solution containing 13-39 mL of German chamomile alcoholic extract (Kneipp Kamillen-Konzentrat, Kneipp Werke) dissolved in 1000 mL of hot water for 10 minutes reduces symptoms when compared to baseline in patients suffering from an uncomplicated common cold (19360).
• Diarrhea. Oral German chamomile has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In children aged 6 months to 6 years with acute diarrhea, using a specific combination product (Diarrhoesan, Dr. Loges + Co. GmbH) containing apple pectin and German chamomile extract for 1-3 days reduces stool frequency and improves symptom relief when compared with placebo (19705).
• Dysmenorrhea. Although there has been interest in using oral German chamomile for dysmenorrhea, there is insufficient reliable information about the clinical effects of German chamomile for this purpose.
• Dyspepsia. Oral German chamomile has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Two specific combination products containing German chamomile (Iberogast, Steigerwald Arzneimittelwerk GmbH; STW-5-S, Steigerwald Arzneimittelwerk GmbH), 1 mL three times daily for 4 weeks, seem to improve symptoms of dyspepsia. The combinations include German chamomile plus milk thistle, peppermint leaf, licorice, caraway, celandine, angelica, and lemon balm, with (Iberogast) or without (STW-5-S) clown's mustard plant (19532). A meta-analysis of studies using Iberogast product suggests that taking 1 mL orally three times daily for 4 weeks reduces severity of acid reflux, epigastric pain, cramping, nausea, and vomiting when compared with placebo (13089). Also, using a preparation containing clown's mustard plant, German chamomile, peppermint, caraway, licorice, and lemon balm (STW 5-II, Steigerwald Arzneimittelwerk GmbH), 1 mL three times daily for up to 12 weeks, improves symptoms in 40% more patients than placebo (12724).
• Fibromyalgia. Although there has been interest in using oral German chamomile for fibromyalgia, there is insufficient reliable information about the clinical effects of German chamomile for this purpose.
• Flatulence. It is unclear if oral German chamomile is beneficial in adults with flatulence post-laparoscopic cholecystectomy. Details: A moderate-sized clinical study in adults undergoing laparoscopic cholecystectomy conducted in Iran shows that German chamomile extract 20 drops given once orally 1 hour before surgery mitigates the severity and incidence of flatulence 2 hours postoperatively when compared with placebo (112364). The interpretation of these findings is limited by the use of self-reported outcomes. In addition, providers had influence on who received German chamomile, raising concerns about selection bias.
• Generalized anxiety disorder (GAD). It is unclear if oral German chamomile is beneficial in adults with GAD. Details: Small clinical studies in adults with GAD show that taking German chamomile extract 220-1500 mg daily for 8-26 weeks improves anxiety rating scores but does not reduce the risk of relapse when compared with placebo (19377,111380). Clinical practice guidelines from the World Federation of Societies of Biological Psychiatry and the Canadian Network for Mood and Anxiety Treatments do not currently recommend German chamomile as monotherapy or adjunctive therapy in patients with GAD (110318).
• Gingivitis. Topical German chamomile has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in people with gingivitis shows that using a toothpaste containing German chamomile, sage, myrrh, eucalyptus, calcium carbonate, and sodium monofluorophosphate twice daily for 30 days reduces gingivitis scores when compared with baseline, but not when compared with standard toothpaste (19702).
• Hemorrhoids. Topical German chamomile might improve symptoms after anal surgery for hemorrhoids. Details: Preliminary clinical research in patients with hemorrhoids shows that German chamomile ointment (Kamillosan, Asta Medica AG) applied twice daily for 6 weeks, in combination with band ligation plus anal dilation surgery, improves anal bleeding, itching, burning, and oozing when compared with surgery alone (19714).
• Hyperprolactinemia. Oral German chamomile might lower prolactin levels, but is not likely to work as well as conventional medications. Details: Preliminary clinical research in female patients with idiopathic hyperprolactinemia shows that taking a syrup containing 10% of a German chamomile dried flower extract 5 mL twice daily for 4 weeks produces a significant decline in serum prolactin levels when compared with baseline. However, the decrease is less than that associated with taking cabergoline 0.25 mg twice weekly for 4 weeks. Serum prolactin levels normalized in 96% of patients taking cabergoline, and 72% of patients taking German chamomile (104806).
• Inflammatory bowel disease (IBD). Although there has been interest in using oral German chamomile for IBD, there is insufficient reliable information about the clinical effects of German chamomile for this purpose.
• Insomnia. Oral German chamomile does not seem to be beneficial in patients with primary insomnia. Details: Preliminary clinical research in patients with primary insomnia shows that taking German chamomile 270 mg twice daily for 28 days does not improve total sleep time, sleep efficiency, sleep latency, sleep quality, waking after sleep onset, or number of awakenings when compared with placebo (19716).
• Leukemia. It is unclear if oral German chamomile is beneficial in children with leukemia. Details: One small clinical study in children aged 2-18 years with acute lymphoblastic leukemia suggests that taking German chamomile flower extract 125 mg in 2.5 mL syrup daily for 30 days during induction chemotherapy is associated with a more rapid recovery in absolute neutrophil counts, but not white blood cell counts, when compared with placebo (103180). However, statistical methods used are unclear, and it is not known if German chamomile altered the effectiveness of chemotherapy.
• Mastalgia. Preliminary research suggests that German chamomile might be effective for reducing the pain of premenstrual mastalgia. Details: Preliminary clinical research in patients with cyclic (premenstrual) mastalgia shows that taking 5 drops of German chamomile extract orally three times daily for 2 months reduces the severity of mastalgia when compared with placebo (104811).
• Nocturnal enuresis. Topical German chamomile has only been evaluated in combination with almond oil; its effect when used alone is unclear. Details: Preliminary clinical research in children with enuresis shows that applying 6 drops of almond oil infused with German chamomile flower to the perineal and suprapubic areas nightly for 6 weeks reduces the frequency of enuresis by about 3 episodes per week when compared with placebo (98621).
• Oral mucositis. Small clinical studies suggest that oral rinses containing German chamomile might help to prevent or treat oral mucositis associated with radiation therapy, chemotherapy, or hematopoietic stem cell transplantation (HSCT). Details: Clinical research shows that using an oral rinse containing German chamomile extract (Kamillosan Liquidum, Asta Media AG) three times daily might help prevent or treat mucositis associated with radiation therapy and several chemotherapy drugs, but not 5-fluorouracil (6655,6656). Other clinical research in patients undergoing HSCT shows that using German chamomile 1% oral rinse twice daily along with standard care reduces the risk of oral mucositis by 67% when compared with standard care alone. However, 0.5% and 2% rinses did not decrease the risk, suggesting that the study may have been underpowered to detect differences (99853). German chamomile has also been studied in combination with other herbal ingredients. One clinical study shows that using an oral rinse containing 1% peppermint oil and 1% German chamomile extract, diluted in water, three times daily starting 1 week before HSCT might help to reduce the severity and duration of oral mucositis induced by high-dose pre-HSCT chemotherapy when compared with placebo. However, the oral rinse does not prevent oral mucositis or reduce the duration of hospitalization when compared with placebo (95622). Another small clinical study in adults with head and neck cancer receiving radiotherapy shows that rinsing with 5 mL of a mouthwash containing German chamomile, peppermint oil, aloe vera, and honey 3 times daily for 60 seconds for 6 weeks starting on the first day of radiotherapy reduces oral mucositis incidence, severity, and pain compared with chlorhexidine and placebo (111291). It is unclear if these findings are due to German chamomile, other ingredients, or the combination.
• Peptic ulcers. Although there has been interest in using oral German chamomile for peptic ulcers, there is insufficient reliable information about the clinical effects of German chamomile for this purpose.
• Periodontitis. German chamomile 1% mouthwash may be similarly effective to chlorhexidine 0.12% mouthwash. Details: Preliminary clinical research shows that using 15 mL of a 1% German chamomile flower mouthwash twice daily for 30 days reduces symptoms and severity of periodontitis by a similar amount when compared with chlorhexidine 0.12% mouthwash (104808).
• Pressure ulcers. Although there has been interest in using oral German chamomile for pressure ulcers, there is insufficient reliable information about the clinical effects of German chamomile for this purpose.
• Radiation dermatitis. It is unclear if topical German chamomile is beneficial for preventing dermatitis caused by radiotherapy. Details: A small clinical study in adults with head and neck cancer undergoing radiotherapy who developed dry desquamation shows that applying a German chamomile 2.5% compress, 20 minutes 3 times daily, results in complete or partial regression of the dry desquamation in 65% and 35% of patients, respectively, and delays the development of moist desquamation by 5-10 days (111376). The validity of these findings is limited by a lack of a comparator group. Another small clinical study in females with breast cancer shows that using a lotion containing a microencapsulated German chamomile extract 0.2%, applied daily after radiation therapy, starting on the first day and continued until the end of treatment, does not improve the incidence or time to onset of any grade of radiation dermatitis on day 35, although it may delay the time to onset of grades 2 or greater, when compared with an identical lotion vehicle control. German chamomile may modestly improve the rate of skin recovery in those with more severe dermatitis over the 15 days following therapy completion (108993). However, due to the small size of the study and short follow-up duration, the validity of these findings is unclear.
• Rhinosinusitis. Using German chamomile nose drops might improve symptoms of rhinosinusitis. Details: Preliminary clinical research in patients with rhinosinusitis shows that using 3 drops of an ethanolic German chamomile extract in each nostril three times daily for 3 weeks reduces symptom scores and improves quality of life when compared with a sesame seed oil placebo (104810).
• Sexual dysfunction. A 5% German chamomile vaginal gel may have similar efficacy to conjugated estrogen vaginal cream in postmenopausal patients. Details: Preliminary clinical research in postmenopausal patients with sexual dysfunction shows that using a 5% German chamomile vaginal gel, 1 gram nightly for 2 weeks then twice weekly for 10 weeks, decreases dyspareunia and increases sexual satisfaction to a similar extent as conjugated estrogen vaginal cream used in the same dosage (104809).
• Vaginitis. Although there has been interest in using oral German chamomile for vaginitis, there is insufficient reliable information about the clinical effects of German chamomile for this purpose.
• Venous leg ulcers. Although there has been interest in using oral German chamomile for venous leg ulcers, there is insufficient reliable information about the clinical effects of German chamomile for this purpose.
• Wound healing. It is unclear if topical German chamomile is beneficial for wound healing. Details: Preliminary clinical research in adults undergoing abrasive tattoo removal shows that applying a topical German chamomile product (Kamille Spitzner, W. Spitzner Arzneimittelfabrik GmbH) three times daily for 14 days reduces wound size by day 4 of treatment when compared with placebo (19718). However, no significant differences in wound healing were observed after 18 days. More information is needed to rate German chamomile for these uses.

• Constipation. Rectal glycerol is beneficial in children and adults with constipation. Details: Glycerol rectal suppositories and enemas are approved by the US Food and Drug Administration (FDA) for over-the-counter use to treat occasional constipation in adults and children at least 2 years of age (15).

POSSIBLY EFFECTIVE

• Athletic performance. Oral glycerol may improve hydration during exercise, but clinical studies evaluating glycerol for improving measures of athletic performance are limited and conflicting. Details: Several clinical studies show that glycerol increases serum osmolality and improves hydration status during exercise (2475,2476,93757,93760,93761,93765). One meta-analysis, including 14 studies and 99 patients, shows that glycerol-induced hyperhydration increases body water by approximately 2.5-fold when compared with water-induced hyperhydration (93757). Also, taking glycerol along with table salt 7.5 grams per liter fluid seems to improve hydration status when compared withg glycerol alone (99162). Research regarding the effects of glycerol on thirst, comfort, temperature regulation, sweating, and heart rate is conflicting (2475,2476,93760,99162). While glycerol may improve hydration status during exercise, it is unclear whether it can improve measures of athletic performance. An early meta-analysis including a total of 36 athletes shows that taking glycerol increases endurance performance by 2.6%. Although this is a small difference, it might be considered meaningful to athletes (93757). Some small clinical studies in athletes suggest that glycerol increases endurance and time to exhaustion, with no effect on heat regulation (2475,2479,93764). However, other small studies suggest that glycerol does not reduce perceived exhaustion or improve exercise performance (2476,93760). Also, glycerol has not been shown to increase time to exhaustion in triathletes (2492). When used to improve athletic performance, glycerol is most often taken at doses of 1-1.5 gram/kg in conjunction with approximately 1.5 L of fluid, 60-120 minutes before competition, and in some cases continued during the competition (2475,93757,93760,93764).
• Ichthyosis. Topical application of a specific product containing glycerol and paraffin may improve symptoms of ichthyosis in children. The benefits of topical glycerol alone in these patients is unknown. Details: A large clinical trial in children aged 1 month to 18 years shows that applying a specific product (Dexeryl, Pierre Fabre Laboratoires) containing glycerol 15% and paraffin 10% for 4 weeks reduces symptoms of non-bullous ichthyosis by at least 50% in an additional 17% of children when compared with a placebo cream. Applying this specific product also improves pruritus by an additional 45% when compared with placebo (93756). It is unclear if these findings are due to glycerol, paraffin, or the combination.

POSSIBLY INEFFECTIVE

• Meningitis. Some clinical research suggests that oral glycerol does not reduce the risk of mortality or seizures in adults and children with bacterial meningitis, although it may reduce certain sequelae. Details: A meta-analysis of five low-quality clinical trials including 1,270 patients shows that adjunctive treatment with glycerol as an oral osmotic agent does not reduce the risk of mortality, seizures, or gastrointestinal symptoms in adults and children with acute bacterial meningitis, although it may modestly reduce the risk of deafness and residual neurological deficit in surviving children (99160). Clinical research included in the meta-analysis has used glycerol 1.5 grams/kg every 6 hours in children aged 2 months to 16 years (93762,93763).
• Prematurity. Rectal glycerol does not appear to reduce the time to enteral feeding in premature infants. Details: Glycerol is used as an enema or given by suppository to facilitate the evacuation of meconium in premature infants in order to reduce the time to enteral feeding. However, two meta-analyses of small studies in preterm infants, that include some of the same studies, show that administering glycerol suppositories does not reduce the number of days to full enteral feeds when compared with placebo or no treatment (99166,112003). However, the interpretation of these findings is limited by the heterogeneity of dosages used in the included studies.

LIKELY INEFFECTIVE

• Stroke. Intravenous glycerol may not improve mortality or symptoms in patients with acute ischemic stroke. Details: Several clinical studies show that intravenous administration of glycerol does not improve symptoms of acute stroke (2480,2481,2482,2484,2486). Additionally, one clinical study in elderly patients with acute ischemic stroke shows that while glycerol can improve initial survival, it does not reduce the risk of overall mortality when compared with placebo (2483).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Dandruff. Topical glycerol has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One clinical trial in adults with dandruff shows that applying a leave-in hair lotion containing glycerol 10%, stearic acid 2.5%, and sunflower seed oil 0.6%, 3 times weekly for 8 weeks, modestly reduces dandruff severity throughout use and for up to one week after the last application when compared with a placebo lotion. The glycerol lotion also reduced total water loss from the scalp by 8% and increased moisturization by 23% (93758). It is unclear if these findings are due to glycerol, other ingredients, or the combination.
• Dry skin. Topical glycerol has only been evaluated in combination with other ingredients for the management of dry skin associated with kidney failure; its effect when used alone is unclear. Details: One small, open-label clinical study in adults with kidney failure and moderate to severe uremic xerosis shows that applying an emulsion containing glycerol 15% and paraffin 10% twice daily for 7 days reduces the severity of xerosis when compared with a placebo emulsion. The glycerol-containing emulsion produces a treatment response in an additional 29% of patients, improves quality of life, and reduces scale density and thickness when compared with placebo (93754). It is unclear if these findings are due to glycerol, paraffin, or the combination.
• Glaucoma. Although there has been interest in using oral glycerol for glaucoma, there is insufficient reliable information about the clinical effects of glycerol for this purpose.
• Intracranial hypertension. Although there has been interest in using intravenous glycerol to reduce intracranial pressure in patients with brain tumors, central nervous system (CNS) trauma, encephalitis, idiopathic intracranial hypertension, meningitis, and Reye syndrome, there is insufficient reliable information about the clinical effects of glycerol for this purpose.
• Meniere disease. It is unclear if intravenous glycerol is beneficial in patients with Meniere disease. Details: A small, uncontrolled clinical study in adults with unilateral, intractable Meniere disease shows that intravenous administration of glycerol 10% at a dose of 0.5 grams/kg once daily for 2 consecutive days, twice monthly for 6 months, reduces the frequency of vertigo attacks and improves quality of life when compared to baseline. Patients reported an average of 3.2 vertigo attacks per month at baseline and 1.2 vertigo attacks per month after 6 months of treatment (106649). The lack of a control group limits the validity of these findings.
• Neonatal jaundice. It is unclear if rectal glycerol improves jaundice-related outcomes in premature infants. Details: A small clinical study in neonates receiving phototherapy for jaundice shows that administering glycerol suppositories has no effect on the duration of phototherapy needed for jaundice treatment, or on bilirubin levels or the rate of bilirubin decline when compared with no glycerol suppositories (99165).
• Obesity. It is unclear if oral glycerol is beneficial in patients who are overweight or obese. Details: One small clinical study in adults on a low-calorie diet shows that taking glycerol 7.5 grams before meals for 6 weeks does not increase weight loss when compared with placebo (2485).
• Otitis externa. Topical glycerol has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical study in adults with otitis externa shows that inserting ribbon gauze soaked in glycerol and ichthammol into the ear canal reduces pain and swelling as effectively as the application of antibiotic and steroid drops three times daily (93759). It is unclear if these findings are due to glycerol, ichthammol, or the combination. More evidence is needed to rate glycerol for these uses.

• Diabetes. It is unclear if dietary peanut oil reduces the risk of developing diabetes. Details: Observational research in adults living in China has found that using peanut oil in the diet over a median of 14 years does not seem to affect the risk of developing diabetes when compared with no use (105886).
• Constipation. Although there is interest in using rectal peanut oil for constipation, there is insufficient reliable information about the clinical effects of peanut for this purpose.
• Coronary heart disease (CHD). Although there is interest in using oral peanut oil to prevent CHD, there is insufficient reliable information about the clinical effects of peanut for this purpose.
• Joint pain. Although there is interest in using topical peanut oil for joint pain, there is insufficient reliable information about the clinical effects of peanut for this purpose.
• Hyperlipidemia. Although there is interest in using oral peanut oil for hyperlipidemia, there is insufficient reliable information about the clinical effects of peanut for this purpose.
• Overall mortality. It is unclear if dietary peanut oil reduces the risk of overall mortality. Details: Observational research in adults living in China has found that using higher amounts of peanut oil in the diet over a median of 14 years is associated with up to a 40% lower risk of overall mortality when compared with no use. However, substituting peanut oil for animal-sourced cooking oil does not seem to reduce overall mortality (105885). More evidence is needed to rate the effectiveness of peanut oil for these uses.
