Caesalpinia crista, commonly known as "fever nut" or "Kuberakshi," has a long-standing use in traditional Ayurvedic and Unani medicine for supporting the female reproductive system. Traditional texts and practitioners have recommended its seeds and extracts for various gynecological concerns such as regulating menstrual cycles, addressing menstrual pain, and supporting fertility. The seeds are sometimes included in formulations meant to tone the uterus, manage leucorrhea, and promote overall reproductive health.

Despite these traditional uses, contemporary scientific research on Caesalpinia crista specifically for female reproductive health is limited. A few animal studies have explored its potential estrogenic and uterine tonic properties, but the evidence is preliminary and not sufficient for strong clinical recommendations. Most of the support for its use in this domain comes from ethnobotanical surveys and classical Ayurvedic texts rather than robust clinical trials or pharmacological studies.

In summary, the use of Caesalpinia crista for supporting the female reproductive system is primarily justified by traditional knowledge, with very limited scientific validation available to date.
