We would like to point out, especially as regards the biological activity of camomile tea (Matricaria chamomilla), that from readily accessible literature, M chamomilla contains chamazulene, which has been shown to have antiallergenic as well as anti-inflammatory properties.1 Further, an en-yn-dicycloether isolated from M chamomilla, has also been shown to elicit anti-inflammatory, anti-anaphylactic, spasmolytic, and bacteriostatic activity.2 Apigenin-7-D-glucoside has also been shown to contribute to the spasmolytic activity of chamomile preparations.3The pure substances mentioned above probably would not exert a significant biological effect at concentrations obtained in a normal human dose of a camomile tea.
