Some clinical studies point to chamomile’s possible benefits for anxiety.

In combination with other herbs, chamomile may be of some benefit for upset stomach, for diarrhea in children, and for infants with colic.

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.

Chamomile can interact with some medications. It increases sedativesedativean agent that induces sleep, relaxes, and reduces tension effects of benzodiazepines (e.g., clonazepam, diazepam), and opiate analgesics (e.g., morphine).
