    Is good to eat raw onion or garlic ?

    A chive is an herb, not a vegetable, but like its Allium vegetable relatives — onions, shallots, leeks, and scallions — chives contain quercetin and sulfur compounds. However, because chives contain fewer of these nutrients they taste milder and are likely to have a milder effect on health conditions.
