Acorus calamus Identity & Plant Part
The botanical entity is Acorus calamus L., family Acoraceae. The part used in this Acorus calamus extract is the rhizome; leaves and roots are not part of the product. Common names include sweet flag, calamus and vacha.
Chemotype and regulation matter more for this species than for most. Indian and East Asian plants of higher ploidy can be rich in beta-asarone, while many North American diploid plants carry almost none. In the United States, calamus and its extracts appear in the FDA list of substances prohibited from direct addition to human food (21 CFR 189.110), and EU rules also limit beta-asarone. Buyers must review the rules of the target market before any food or supplement use.
