Onions contain a considerable amount of sulfuric oils. Sulfur is a beautifier of the highest order because it cleanses the liver and skin, has antiseptic properties, and help builds connective tissue.
The most unique compound in onions is quercetin. Quercetin helps to eliminate free radicals in the body, to protect and regenerate the beauty vitamin (vitamin E), to inactivate harmful effects of heavy metals, and to decrease capillary fragility (a useful factor in healing varicose veins).
Onions cause thick, clumped blood to thin out.
Belle Boone Beard, a sociologist, who worked for the National Institute of Aging, interviewed more than 85 people who lived to hundred years and beyond. One commonality was that they all enjoyed eating onions. Some declared that they ate an onion with every meal, every day. Beard came to believe that onions play a major role in longevity.
