# biology | Onion extract normalizes cholesterol and sugar

Bulb Extract (Allium cepa) substantiallyreduces elevated glucose (sugar) and total cholesterol in diabetic rats. In addition, these rodents also took the antidiabetic drug metformin. The results of this study were announced at the 97th annual meeting of the Endocrine Society in San Diego. It turns out that such a cheap and affordable dietary supplement as onion extract can theoretically be used in the treatment of patients with diabetes.

As reported on the pages of the resource EurekAlert! Science News, Leading Researcher MD at Nigerian University of Delta (Abraka) Anthony Ojieh notes:

Onions are cheap and affordable and are included in the diet. Potentially, it can be used to treat patients with diabetes.

Three groups of rats with diabetes Ojieh and his colleaguesgave metformin and various dosages of onion extract (200, 400 and 600 milligrams per kilogram of rodent weight per day) and looked to see if it enhances the effect of the drug. Metformin and onion extract were also given to three groups of rats that did not have diabetes. Two control groups (rats with and without diabetes) did not receive either metformin or onion extract. In addition, two more groups (rats with diabetes and without it) received only metformin, and they did not give onion extract. Each group included five rodents.

Onion extract in dosages 400 and 600milligrams per kilogram of rat weight per day significantly reduced blood sugar levels (by 50% and 35%) compared with the condition before this supplement was given to rodents.

It is also noted that Allium cepa reduces overallcholesterol in diabetic rats. 400- and 600-milligram dosages had the maximum effect. In non-diabetic rats, onion extract increased average weight; in rats with diabetes, it did not have a similar effect. Onions in themselves are not very high in calories, but they stimulate metabolism and increase appetite.

At the same time, neither metformin nor onion extract cured the damage that was caused by diabetes to the pancreas of rats.

The extract was extracted from regular onions, availableon sale in the local market. At the same time, to use the extract as a medicine, it has to be purified to isolate only the active ingredients in the appropriate dosage, Ojieh notes. Scientists have yet to figure out a mechanism that allows onions to lower their blood sugar. Ojieh reports that there is currently no explanation for this phenomenon among researchers.

From the message it follows that onion itselfthe extract is not a medicine, but an auxiliary additive in relation to antidiabetic medicines. And, of course, the studies that are at the initial stage of the study do not yet give reason to consider onion extract exactly the means by which you can lower the level of sugar and cholesterol.

Warnings

Raw onions can cause skin irritation,mucous membranes and eyes. This is due to the release of sulfur allyl gas during the onion cutting process. When this gas is mixed with water, it is converted to sulfuric acid. Allyl sulfide is most concentrated at the edges, especially this refers to the root. The considered effect can be minimized by pre-immersing the onion in cold water for several minutes and only then chop or chop the onion. Water must be drained.

Attitude towards onions and garlic has changed from Mediumcenturies. Now they are considered useful and even find new healing properties. Are you aware of other good qualities of onions? Or is his smell so unpleasant that you no longer want to use it as a medicine? What anti-diabetic properties of which plants, apart from chili peppers, do you know?
