The domesticated garlic plant does not produce seeds, but is grown from bulbs. These bulbs, whose segments are usually called "cloves" by cooks, are the part of the plant most commonly eaten, though some cooks also use the early spring shoots. These shoots are often pickled in Russia and states of the Caucasus and eaten as an appetizer.

Garlic is most often used as a seasoning or a condiment, and is believed to have some medicinal value, notably against hypertension. When crushed or finely chopped it yields allicin, a powerful antibiotic and anti-fungal compound.

The cloves are used by aficionados for infections, especially chest problems, digestive disorders, and fungal infections such as thrush. They are claimed to be an effective long-term remedy for cardiovascular problems reducing excessive blood cholesteral levels, atherosclerosis, the risk of thrombosis, and hypertension but these claims are disputed as there has been no clinical trial that has demonstrated any such benefits. Garlic is also alleged to help regulate blood sugar levels, and so can be helpful in late-onset diabetes, though people taking insulin should not consume medicinal amounts of garlic without consulting a physician. Best used fresh.
