Prickly Chaff Flower (Achyranthes aspera) has been widely used in traditional medicine systems, particularly in Ayurveda and other South Asian herbal practices, for supporting women's reproductive health and the uterus. Historical records and traditional texts reference its use for managing menstrual disorders, stimulating menstruation, aiding in childbirth, and addressing uterine inflammation. Some Ayurvedic formulations include Prickly Chaff Flower as a component for promoting uterine tone and supporting post-partum recovery.

The traditional rationale is largely based on empirical use and the herb's reputed influence on blood flow and muscle tone. However, modern clinical studies specifically validating its efficacy for uterine health are limited. Some laboratory studies have explored its effects on smooth muscle tissue and its anti-inflammatory properties, but these are not sufficient to draw firm conclusions about benefits for the uterus in humans. As a result, the use of Prickly Chaff Flower for uterine support is primarily justified by tradition, with modest support from preliminary scientific inquiry.
