Quick Summary

Saraca asoca (Roxb.) de Wilde, popularly known as Ashoka or the “Sorrowless Tree,” is a sacred evergreen tree belonging to the Fabaceae family. It is celebrated in Ayurvedic medicine as a premier uterine tonic, clinically effective for managing gynecological conditions such as Polycystic Ovarian Syndrome (PCOS), menorrhagia, and leucorrhea. Modern scientific evidence validates its role as a multi-functional therapeutic agent possessing potent anti-inflammatory, anticancer, antioxidant, and neuroprotective activities, primarily driven by its rich content of catechins, flavonoids, and tannins. Beyond women’s health, it is studied for its cardioprotective potential and ability to mitigate chronic stress-induced depression. Commonly utilized as bark decoctions, Ashokarishta (fermented preparation), and seed extracts, it maintains a strong safety profile. However, due to its estrogenic potency, it is classified as Caution during pregnancy and is highly prone to adulteration with Polyalthia longifolia.

Key Therapeutic Benefits

  1. Normalization of Hormonal Profiles in PCOS Saraca asoca extracts significantly reduce elevated levels of serum testosterone, insulin, and luteinizing hormone in metabolic disorder models. It works by normalizing the perturbed hormonal profile and improving ovulation status by decreasing cystic follicles. (Bu, 2023; Swar, 2017; Himaja, 2025)
  2. Antiproliferative Control of Endometrial Thickening The methanolic bark extract effectively inhibits estrogen-induced endometrial thickening and keratinizing metaplasia.
