Two distinct plants are known as chamomile and are used interchangeably: German and Roman chamomile. Although distantly related botanically, they both look like miniature daisies and are traditionally thought to possess similar medicinal benefits.
Over a million cups of chamomile tea are drunk daily, testifying to its good taste, at least. Chamomile was used by early Egyptian physicians for fevers, and by ancient Greeks, Romans, and Indians for headaches and disorders of the kidneys, liver, and bladder.
The modern use of chamomile dates back to 1921, when a German firm introduced a topical form. This cream became a popular treatment for a wide variety of skin disorders, including eczema, bedsores, skin inflammation caused by radiation therapy, and contact dermatitis (eg, poison ivy).
Chamomile cream is applied to the affected area 1 to 4 times daily.
Chamomile tea can be made by pouring boiling water over 2 to 3 heaping teaspoons of flowers and steeping for 10 minutes.
Chamomile tinctures and pills should be taken according to the directions on the label. Alcoholic tincture may be the most potent form for internal use.
There is no reliable evidence that chamomile is effective for the treatment of any health condition.
A controlled study of 161 individuals found chamomile cream equally effective as 0.25% hydrocortisone cream for the treatment of eczema . ^ However, this study did not use a placebo group, and does not appear to have been double-blind . For this reason, the results are not reliable. (For information on why double-blind studies are so important, see Why Does This Database Rely on Double-blind Studies? )
A study of 72 individuals with eczema found somewhat odd results: In this trial, chamomile was not significantly more effective than placebo, but both were better than 0.5% hydrocortisone cream. ^ It is difficult to interpret what these paradoxical results actually mean, but they certainly cannot be taken as proof that chamomile cream is effective.
In a double-blind study, chamomile cream proved lesseffective for reducing inflammation of the skin than hydrocortisone cream or witch hazel cream. ^ Finally, in a single-blind trial, 50 women receiving radiation therapy for breast cancer were treated with either chamomile or placebo. ^ Chamomile failed to prove superior to placebo for preventing skin inflammation caused by the radiation therapy.
A double-blind, placebo-controlled trial of 164 individuals did not find chamomile mouthwash effective for treating the mouth sores caused by chemotherapy with the drug 5-FU. ^
