The finding is consistent with animal studies. One such study, presented at the Endocrine Society’s 97th annual meeting in San Diego, was conducted on diabetic rats.
When the rats were given Allium cepa – or onion bulb extract – in combination with metformin, their blood glucose and cholesterol levels were significantly reduced.
Metformin is a medication that helps the insulin you produce work better.
The rats, all of which were engineered to have diabetes, were divided into three groups. All the groups were given metformin, and each was given a different dose of onion extract – 200, 400, or 600 milligrams per kilogram of body weight.
