Onions have anti biotic

Onions have anti biotic, antiseptic, antimicrobial and carminative properties to help you stay away from infections. The flavonoids in onion tend to be more concentrated in the outer layers of the flesh. To maximize your health benefits, peel off as little of the fleshy, edible portion as possible when removing the onions outermost paper layer. Even a small amount of overpeeling can result in unwanted loss of flavonoids. For example, a red onion can lose about 20% of its quercetin and almost 75% of its anthocyanins if it is overpeeled.
