Chamomile has not been well studied with people so there is little evidence to support its use for any condition.
Some early studies point to chamomile's possible benefits for mouth ulcers and certain skin conditions and for mouth ulcers caused by chemotherapy or radiation.
In combination with other herbs, chamomile may be of some benefit for upset stomach, for diarrhea in children, and for infants with colic.
NCCAM-funded research on chamomile includes studies of the herb for generalized anxiety disorder and abdominalabdominalrelating to the stomach and intestines pain caused by children's bowel disorders.
There are reports of rare allergic reactions in people who have eaten or come into contact with chamomile products. Reactions include skin rashes, throat swelling, shortness of breath, and anaphylaxis (a life-threatening allergic reaction).
People are more likely to experience allergic reactions to chamomile if they are allergic to related plants in the daisy family, which includes ragweed, chrysanthemums, marigolds, and daisies.
