Acorus gramineus Identity & Plant Part
The botanical entity is Acorus gramineus Aiton, family Acoraceae, known as grassy-leaved sweet flag and in Chinese trade as shi chang pu. The part recorded for this Acorus gramineus extract is the whole plant; the master data does not isolate the rhizome.
The genus invites confusion. Acorus calamus, the common sweet flag, is a larger plant with a separate extract page, and its rhizome is the better-known commercial material. Aromatic phenylpropanoids of the asarone type occur across the genus, and some markets restrict them, so buyers formulating for a given region need to review the asarone rules that apply there before using any Acorus ingredient.
