Ingredient Type: Botanical
Also Known As: Momordica charantia L., Bitter melon fruit extract, Karela
Bitter melon (Momordica charantia L.) is native to the tropics and has been used for centuries as a therapeutic agent in Asia, Africa, and Latin America. Traditionally the fruit of the bitter melon has been used to treat diabetes, psoriasis, infertility, gastrointestinal cramps, infections, and cancer. It is most frequently used today, however, to help manage blood sugar. Teas made from the stems and leaves of the bitter melon plant are also used medicinally.
Bitter melon is also consumed as a foodstuff and is found as an ingredient in some south Asian curries. The raw fruit is available in specialty Asian markets where it is known as karela.
Bitter melon is used in health supplements today as blood sugar support due to the fact that it contains a chemical that acts like insulin in the body.
Orally, bitter melon is used to treat diabetes, psoriasis, gastrointestinal upset, ulcers, colitis, constipation, intestinal worms, urinary tract stones (kidney stones), fever, and hepatic disease. It is also used orally to induce menstruation and as supportive therapy for patients with AIDS/HIV.
WHAT DOES SCIENCE TELL US?
Bitter Melon Possibly Helps Improve Blood Glucose:
Some preliminary research shows that bitter melon fruit, fruit juice, and fruit extract improves glucose tolerance, reduces blood glucose levels, and lowers glycosylated hemoglobin (HbA1C) in patients with type 2 diabetes (1,2,3,4,5).
Extracts of bitter melon fruit appear to be safe when used orally and appropriately for up to 3 months.
