Chamomile is a small daisy-like flower dried and brewed as a mild tea. Matricaria chamomilla is the German kind. It is the type most often found in tea bags, capsules and skin creams.
People drink it to wind down at night. Others use it to settle a sour or crampy stomach. On the skin it is used for mild rashes and as a mouth rinse.
Here is the honest verdict. A few small human trials hint at mild help for anxiety, and the sleep results are weak. Long use in tradition is not proof that a herb works, and it is not proof that it is safe.
Nobody has pinned down how chamomile works in the body. The lab findings below come from cells and animals, not from people.
In cell studies, a flavonoid called apigenin binds to the same brain receptors as some calming drugs. That may explain the relaxed, sleepy feeling some people report. It has not been confirmed in humans.
In test tubes and in animals, chamomile extracts slow some inflammation signals. They also relax gut muscle in lab dishes. Whether a cup of tea does this inside you is unknown.
Part of the effect may be the ritual. A warm drink and a quiet half hour calm many people on their own.
Chamomile is sold in many everyday forms.
Tea bags and loose dried flowers are the most common. These are ordinary food products in most shops.
Capsules and tablets hold a dried extract. Labels often state how much apigenin they contain.
Tinctures are alcohol-based liquid drops. Creams, gels and lotions are used on the skin.
The blue essential oil is very concentrated. It is meant for scent and for diluted skin use, never for swallowing.
Chamomile has one of the longest records of any garden herb. That record says nothing about whether it works.
Egyptian, Greek and Roman writers named it for fevers and stomach complaints. Medieval European herbals listed it for cramps, wind and poor sleep.
In central Europe it became a household tea for children and for sore skin. German herbal practice later adopted it formally, and German Commission E monographs described it for gut upset and skin irritation.
These were traditional and expert judgements of their time. They were not built on modern trials.
Call emergency services if your lips, tongue or throat swell, if you wheeze, or if you struggle to breathe. These are signs of a severe allergic reaction.
Stop using it and see a doctor if you get hives, a spreading rash, or sudden stomach pain.
See a doctor promptly if you bruise easily or bleed more than usual while taking a blood thinner.
Book an appointment if anxiety, poor sleep or stomach trouble lasts more than two to four weeks.
In the United States, chamomile tea is an ordinary food and chamomile capsules are sold as dietary supplements. In the United Kingdom and the European Union, some chamomile products are registered as traditional herbal medicines, which means they are approved on long use rather than on trial proof.
