The daisy-like flower of this herb is dried and used as tea or in a capsule or extract.
Chamomile is generally considered safe. The most likely side effect is an allergic reaction, especially in people who are allergic to ragweed or sunflowers. Allergic reactions may include skin irritation, itchy eyes, sneezing, and runny nose. People very rarely have a severe and life-threatening allergic reaction (anaphylaxis). In high doses, chamomile may lead to drowsiness, sedation, and vomiting.
