Himalaya Karela is a pure herb extract. Karela also known as Bitter Melon or Momordica Charantia is a herb that helps maintain normal blood sugar levels and keeps body functions operating normally. Eating Karela over long period of time promotes normal glucose levels in the blood and urine. At least three different groups of constituents in Bitter Melon have been reported to have benefits in maintaining normal blood sugar levels. These include a mixture of steroidal saponins known as charantin, insulin-like peptides, and alkaloids. Karela contains Gurmarin, a polypeptide considered to be similar to bovine insulin, which has been shown in experimental studies to achieve a positive sugar regulating effect by suppressing the neural response to sweet taste stimuli.
