Since leech therapy increases blood circulation, placing leeches on thinning or bald areas helps improve blood circulation and delivery of nutrients that assist in making hair follicles strong, thereby aiding in the promotion of hair growth.

Treating Osteoarthritis/Arthritis

The anti-inflammatory and anesthetic properties in the leech’s saliva reduce pain and tenderness at the site of the affected joint.

Treating Diabetes

Leech salivary glands contain Hirudin, a substance that suppresses the blood clotting mechanism. Hirudin also has a blood diluting effect, so apart from preventing blood clots; it also thins the blood, allowing the blood to circulate more efficiently, relieving pressure on the heart and blood vessels.

Treating Migraines

Leeches suck just enough blood to get the bloodstream flowing, alleviating the symptoms from migraines. Leeches can also cause vasodilation, meaning the vessels are widened, thus lowering the pressure on the walls of these vessels, improving blood flow.

Cancer

Cancer treatments using leech therapy are being explored because of the platelet inhibitors and special enzymes contained in leech saliva. While people with certain blood cancers are not advised to use leech therapy, it has been shown to slow the effects of lung cancer.
