What is chamomile?
Chamomile is a family of daisy-like plants. Active ingredients in chamomile include the essential oil bisabolol and plant nutrients called flavonoids.
The chamomile flower is dried and used as tea or in a capsule or applied topically as an extract.
Of the many species of chamomile, just 2 are typically used in dietary supplements: Matricaria chamomilla and Chamaemelum nobile.
Chamomile is most often consumed as a tea to reduce anxiety.

Does chamomile work?
The scientific evidence supporting any use of chamomile is weak. However, some evidence shows chamomile may have a small effect in improving sleep quality and helping to relieve anxiety and depression.
What are the possible side effects of chamomile?
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).
What drug interactions occur with chamomile?
Chamomile may reduce the absorption of some drugs taken by mouth. Chamomile may also increase the effects of drugs that prevent blood clots (anticoagulants) and sedatives (including alcohol) and decrease the absorption of iron supplements. Chamomile could interfere with the effects of tamoxifen, hormone replacement therapy, and estrogen-containing oral contraceptives.
Chamomile may help ease symptoms of anxiety and depression and improve sleep quality, but the effects are likely to be small. Chamomile appears to be reasonably safe.
People taking anticoagulants (such as warfarin), sedatives (including alcohol), iron supplements, tamoxifen, hormone replacement therapy, and estrogen-containing oral contraceptives should talk to their doctor before using chamomile.
