Which chamomile?

German chamomile preparations use the flower heads of Matricaria recutita. EMA recognizes traditional use for mild digestive complaints such as bloating and minor spasms; this is not the same as efficacy established by clinical trials. 1

Questions people ask

Does it reliably treat insomnia?

The 2019 review found no significant benefit in its one insomnia trial. That differs from improvements in general sleep-quality measures. 2

Is the digestive use clinically proven?

EMA classifies this as traditional use, supported by longstanding experience rather than sufficient clinical trials. 1

Can everyone drink it safely?

No. Chamomile can trigger allergic reactions, including rare severe reactions. 3
