Obtusin is primarily used in traditional medicine for its laxative effects, helping to relieve constipation by stimulating bowel movements. It is also studied for its potential anti-inflammatory and antioxidant properties, which may support its use in managing inflammatory conditions and oxidative stress-related diseases. Research explores its role in cancer prevention due to its ability to induce apoptosis in certain tumor cells. Additionally, obtusin is used as a natural pigment in some herbal formulations, contributing to the color and therapeutic value of the product. Its presence in legume seeds also makes it relevant in agricultural and nutritional studies, particularly in understanding plant defense mechanisms and seed quality.
