Oh yes they do!!! They suck blood for food, now this may sound disgusting but you can get health benefits from letting leeches suck your blood.. They produce several important substances that make its bite very special, including an anticoagulant (hirudin), a local vasodilator, and a local anaesthetic. These substances allow continued bleeding that mimics venous circulation for up to 10 hours after the leech has detached (and the anaesthetic makes the bite painless). The leech can also remove any congested blood to allow normal circulation to return to the tissues and prevent gangrene from setting in. Leeches may also be used to treat black eyes. And hirudin, the anticoagulant, may be used in the treatment of inflammation of the middle ear. Hirudin may also eventually be used in invitro blood sampling. Researchers have found that the anticoagulant and clot-digesting properties of substances in leech saliva make them potentially useful for the treatment of heart attacks and strokes. hop
