Alfalfa (Medicago sativa) is a small herbaceous plant native to South and Central Asia. Rich in vitamins K and C, fiber, and valuable active compounds such as saponins, phytoestrogens, and canavanine, alfalfa helps lower cholesterol, balance hormones, strengthen resistance, and improve metabolism. In particular, saponins help effectively remove bad cholesterol, making alfalfa notable for supporting cardiovascular protection and blood sugar regulation.
