Karela (Bitter Gourd)

Herbal Supplements

Karela, commonly known as bitter gourd or bitter melon (Momordica charantia), has a long history of use in traditional medicine systems across Asia, Africa, and Latin America. Research suggests that bioactive compounds in bitter gourd, including charantin, polypeptide-p, and vicine, may support healthy blood sugar metabolism by influencing glucose uptake and insulin signaling pathways. Studies indicate that bitter gourd extracts may also contribute to liver health by promoting antioxidant enzyme activity and supporting the body's natural detoxification processes. Additionally, preliminary research has explored its potential role in skin health, possibly linked to its rich content of vitamins A and C along with various anti-inflammatory compounds. Bitter gourd is most commonly consumed as a fresh juice or taken as a standardized extract in supplement form.
