The use of the Asoka Tree (Saraca asoca) to support or treat menstrual irregularity is primarily justified by traditional medicine, particularly within Ayurveda. In classical Ayurvedic texts, the bark of the Asoka Tree is described as having properties that help regulate menstrual flow, alleviate excessive bleeding (menorrhagia), and address other gynecological disorders. Formulations like "Ashokarishta," which prominently feature Asoka bark, are widely used in traditional Indian medicine for managing various menstrual disorders.

Scientific validation for these traditional uses is limited. A small number of animal studies and preliminary human trials have indicated potential estrogenic and anti-inflammatory effects of Asoka bark extracts, which could theoretically influence menstrual physiology. Some studies have reported that extracts may modulate uterine contractions or reduce abnormal bleeding, but these studies are generally of low quality, with small sample sizes, lack of rigorous controls, or inadequate blinding. Comprehensive clinical trials in humans are lacking, and there is insufficient high-quality evidence to firmly establish efficacy or safety for this indication according to modern scientific standards.

In summary, the use of Asoka Tree for menstrual irregularity is deeply rooted in traditional practice and is widely accepted in Ayurveda. However, while there are some promising preliminary findings, robust scientific validation remains insufficient at present.
