Sanguisorba (commonly known as burnet) has been used in traditional medicine systems, particularly in Chinese and European herbalism, for its purported benefits on various body systems, including the reproductive system. In Traditional Chinese Medicine (TCM), Sanguisorba officinalis (Di Yu) is often used to help control excessive uterine bleeding, manage menstrual disorders, and support postpartum recovery. Historical herbal texts from Europe also mention its use for "women's complaints," which sometimes included menstrual regulation or alleviation of heavy bleeding.

However, there is a lack of robust scientific studies specifically validating Sanguisorba’s effects on the reproductive system. Most modern research has focused on its anti-inflammatory, astringent, and hemostatic activities, which provide a plausible mechanism for its traditional use in managing bleeding disorders. These properties may explain its historical use in addressing issues like heavy menstrual bleeding or postpartum hemorrhage.

In summary, the use of Sanguisorba to support the reproductive system is primarily based on traditional knowledge rather than well-established scientific evidence. While its astringent and hemostatic qualities offer some rationale, rigorous clinical trials are lacking. Therefore, evidence for its efficacy in supporting the reproductive system is rated as limited.
