The medical properties of chives are similar to those of garlic, but weaker; the faint effects in comparison with garlic are probably the main reason for its limited use as a medicinal herb. Containing numerous organisulplide compounds such as allyl sulfides and alkyl sulfoxides, chives have a beneficial effect on the circulatory system, acting upon it by lowering the blood pressure. As chives are usually served in small amounts and never as the main dish, negative effects are rarely encountered, although digestive problems may occur following over-consumption

Chives are also rich in vitamins A and C, and contain trace amounts of sulfur and iron.
