Achyranthes, particularly Achyranthes aspera, has been used in traditional medicine systems such as Ayurveda and Unani for the management of menorrhagia (excessive menstrual bleeding). The herb is described as having astringent and haemostatic properties, which are believed to help control abnormal uterine bleeding. Classical Ayurvedic texts mention the use of Achyranthes in formulations meant to regulate menstrual flow and treat gynecological disorders, including menorrhagia.

Scientific evidence supporting the efficacy of Achyranthes for menorrhagia is limited. A few animal studies have examined the haemostatic and uterotonic effects of Achyranthes extracts, suggesting some potential for reducing bleeding. However, well-designed human clinical trials are lacking, and the available studies are generally of low quality or are limited to preclinical models. Most references to its use for menorrhagia are based on ethnobotanical surveys and traditional knowledge rather than robust scientific validation.

In summary, the use of Achyranthes for menorrhagia is primarily rooted in traditional medicine, with only low to moderate preclinical evidence and a lack of high-quality clinical data to confirm its efficacy and safety for this specific indication.
