Eating Onions Promotes Health
Recently, American scientists discovered prostaglandin A in onions, which expands peripheral arteries and reduces peripheral vascular resistance, thus lowering blood pressure. Additionally, it increases urine output, promotes sodium excretion, reduces resistance in coronary arteries, increases blood flow, and helps prevent coronary heart disease.
Onions also contain abundant selenium, a trace element with strong anticancer properties. Selenium is a powerful antioxidant that accelerates the breakdown of peroxides in the body, depriving malignant tumors of molecular oxygen and thereby inhibiting their growth. Moreover, selenium stimulates the production of glutathione, a substance that binds carcinogens with its “scientific handcuffs,” rendering them harmless, then expelling them through the digestive tract. Onions also contain a compound called quercetin, considered one of the best known natural anticancer substances.
A British professor’s study revealed that onion vapor has remarkable healing effects on inflamed wounds. Crushing onions and applying them externally treats ear pain. Chewing onions helps relieve colds. Adding a bit of onion juice to cough syrup enhances its effectiveness. Onions also enhance gastrointestinal tone, stimulate secretion of digestive juices, and can treat non-dysenteric enteritis and vitamin deficiency disorders.
