VALUES
Onions are a very rich source of fructo-oligosaccharides. These oligomers stimulate the growth of healthy bifidobacteria and suppress the growth of potentially harmful bacteria in the colon. In addition, they can reduce the risk of tumors developing in the colon.
Onion extracts, rich in a variety of sulfides, provide some protection against tumor growth. In central Georgia where Vidalia onions are grown, mortality rates from stomach cancer are about one-half the average level for the United States. Studies in Greece have shown a high consumption of onions, garlic and other allium herbs to be protective against stomach cancer.
The World Health Organization (WHO) supports the use of onions for the treatment of poor appetite and to prevent atherosclerosis. In addition, onion extracts are recognized by WHO for providing relief in the treatment of coughs and colds, asthma and bronchitis. Onions are known to decrease bronchial spasms. An onion extract was found to decrease allergy-induced bronchial constriction in asthma patients.
Onions are a rich source of flavonoids, substances known to provide protection against cardiovascular disease. Onions are also natural anticlotting agents since they possess substances with fibrinolytic activity and can suppress platelet-clumping. The anticlotting effect of onions closely correlates with their sulfur content. Onion can improve lung function, especially in asthmatics. The more pungent varieties of onion appear to possess the greatest concentration of health-promoting phytochemicals.
Onions are very beneficial to women with scanty and painful menses. In case of sunstroke, use of onions relieves thirst and mitigates the effects of the sunstroke. Besides, onion has several medicinal uses described by various authors as remedy or cure for different ailments.
Researchers at the University of Utah who carried out the study, examined the health values in onion and discovered that quercetin, the compound most commonly associated with onions, may reduce blood pressure by an average of five millimeters of mercury (Hg) especially if eaten raw. Sulphur compound present in raw onion will also help to prevent the growth of cancer cells. Likewise, onion is also good and effective in the treatment of anaemia, bleeding piles, stomach aches, while the juice can be applied externally as an antiseptic. It also prevents and can treat teeth disorders. The Indians, Chinese and the Egyptians know and appreciate the medicinal value of onion as well as garlic.
