Achyranthes aspera Identity & Plant Part
The botanical entity is Achyranthes aspera L., family Amaranthaceae, known as prickly chaff flower and, in Ayurvedic usage, apamarga. The part used in this Achyranthes aspera extract is the whole plant; the master data records no single organ.
The species is not Achyranthes bidentata, the source of niu xi, which is used as a root and sits on its own page. The two plants share a genus and some constituent families, namely triterpenoid saponins and ecdysteroids, but the plant part and the species differ, so the pages are not interchangeable. Whole-plant material also covers a wider range of tissues than a single organ, so descriptions of Achyranthes aspera stress species identity over any organ-specific claim.
