Onions were used as medicine in India as early as the 6th century. They were exceedingly popular with the ancient Greeks and Romans as well.

Benefits of Eating Raw Onions: Onion Nutrition
Raw onions provide better results. Research says consuming the juice of two raw onions every morning thins the blood successfully. Half ounce onion juice along with a spoon of honey works like a potent expectorant which eases out congestion of the chest and greatly allays sinusitis related discomfort.
The flavanoids present in the onion are in greater concentration in the outer layers of the flesh than in the inner. In order to make the most of the health-promoting benefits, peel off very little of the outer edible portion as possible. Over peeling results in an undesirable loss of flavanoids.
When onions are used in soup, the quercetin does not get lost; it gets transferred to the water part of the soup. Using low-heat technique to prepare soup, you can conserve the health benefits linked to this vital flavanoid. Consuming quercetin by eating an onion, instead of having a quercetin supplement provides a better shield from oxidative damage.
