About German Chamomile
German chamomile (Matricaria recutita) has modest RCT support for generalized anxiety disorder (Amsterdam et al.) and weaker evidence for sleep quality. Contains apigenin and bisabolol. Possible ragweed-family allergy cross-reactivity; theoretical additive effect with sedatives and anticoagulants. Note: bare 'Chamomilla' can also denote a homeopathic remedy, which is not scoreable.
What German Chamomile supports
- May modestly reduce generalized-anxiety symptoms — supported by a small number of RCTs, effect size moderate
- May slightly improve sleep quality — limited, lower-quality evidence
How much German Chamomile to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
220–1500
mg
Standardized extract (e.g. 1.2% apigenin) 220-1500 mg/day used in generalized-anxiety RCTs.
Clinical evidence
Moderate clinical evidence. A few RCTs support anxiety benefit for standardized extract; sleep evidence is weaker and mixed.
