What is Chamomile?

In plain words

Chamomile is a flowering herb commonly made into tea or extracts. The body absorbs and breaks down some of its plant chemicals, which may affect signals involved in calmness and inflammation. Researchers study it for anxiety, sleep problems, and digestive discomfort, but evidence of benefit is limited. It can cause allergic reactions, especially in people allergic to related plants such as ragweed.

Technical definition

Chamomile (Matricaria recutita, also called German chamomile) is a botanical in the Asteraceae family whose flower preparations contain flavonoids such as apigenin and volatile constituents such as bisabolol. Apigenin interacts with benzodiazepine-binding sites on GABA-A receptors in laboratory studies, suggesting effects on inhibitory neurotransmission, but whole-extract mechanisms and clinical relevance remain uncertain. Chamomile is marketed in teas and dietary supplements; in the United States, dietary supplements are not FDA-approved to treat disease.
