A new study has found that Allium cepa, which is extracted from onion helps to reduce the blood sugar and cholesterol. In the research conducted on rats, this onion extract was found to cause an increase in weight among nondiabetic ones but not diabetic ones. Though it is said that onion is not high in calories, it greatly stimulates the metabolism and appetite which ultimately increases feeding. Allium cepa is prepared from onion bulb which we get in local markets. It would be purified for quantifying only the active ingredients for adequate dosing to humans.
