Karela consists of fruit of Momordica charantia Linn.; a monoecious climber found throughout the country often under cultivation, upto an altitude of 1500 m. Bitter melon (Momordica charantia) has traditionally been used as a remedy for lowering blood sugar in patients with diabetes. Preliminary data exists on bitter melon use in HIV and cancer. Extracts and powdered formulations of the fruit are most frequently used, although teas made from the stems and leaves are sometimes recommended.

  Pharmacology :  
Momordica charantia:It is good to increase the appetite, as digestive aid, Liver stimulant, as stomachic, as gastrointestinal prokinetic agent, and mild laxative. Haritaki has proven gastrokinetic effect i.e. it helps in moving the contents of stomach earlier. The fruits are stomachic and carminative, tonic and have alternative properties. It is also used in heart diseases, respiratory diseases, pain, fever, inflammation, piles, anemia, diabetes and gastric disorders
Traditional Uses:Traditionally it is used in fever, jaundice. It is mainly used in diabetes. 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.
  Marker constituents:Bitter compound  
Mode of Action: Firstly its effect over the gluconeogenic enzymes, and second it may exert its action on the transporters of glucose. Vicine, charantin, and polypeptide-P in both animals and humans increase glucose uptake and glycogen synthesis in the liver, muscle, and adipose tissue, and improve glucose tolerance. Studies with hepatic enzymes in mice revealed reduction in glucose-6-phosphatase and fructose-1,6-bisphosphatase activity, and increased glucose oxidation by G6PDH pathway. Bitter melon displays cytotoxic activity against leukemic cells in vitro (guanylate cyclase inhibitor). The MAP30 extract has a cytostatic effect on MDA-MB-231 human breast cancer cells xenografted into mice. MAP30 also demonstrates dose-dependent inhibition of HIV-1 integrase leading to poor viral DNA integration, thus inhibiting T lymphocyte and monocytes.
