Chives grow wild throughout most of the northern hemisphere, forming perennial clumps about 5 in (12 cm) high. Chives consist of an underground bulb, long hollow tubular leaves, and globe-shaped purple flower heads. They are the mildest and smallest member of the onion family and lack the bitterness of raw onions. Their leaves are often used as a garnish for salads or to flavor foods such as fish, potatoes, and soup. What effect does eating chives have on the circulatory system? Discuss
