Since the time of ancient Egypt, leeches have been used in medicine to treat nervous system abnormalities, dental problems, skin diseases, and infections.

Today, they鈥檙e mostly used in plastic surgery and other microsurgery. This is because leeches secrete peptides and proteins that work to prevent blood clots. These secretions are also known as anticoagulants. This keeps blood flowing to wounds to help them heal.

Currently, leech therapy is seeing a revival due to its simple and inexpensive means of preventing complications.

How does leech therapy work?

Medicinal leeches have three jaws with tiny rows of teeth. They pierce a person鈥檚 skin with their teeth and insert anticoagulants through their saliva. The leeches are then allowed to extract blood, for 20 to 45 minutes at a time, from the person undergoing treatment. This equates to a relatively small amount of blood, up to 15 milliliters per leech. Medicinal leeches most often come from Hungary or Sweden.

There are several situations in which leech therapy may be used. People who may benefit include those who risk limb amputation due to the side effects of diabetes, those who have been diagnosed with heart disease, and those who are undergoing cosmetic surgery in which they risk the loss of some of their soft tissue. The therapy has also been recommended to treat blood clots and varicose veins.

People with anemia, blood clotting conditions, or compromised arteries are not candidates for leech therapy. Children under the age of 18 years old and women who are pregnant are also usually advised to avoid it.

Medical applications for leech therapy :

During a session, live leeches attach themselves to the target area and draw blood. They release the proteins and peptides that thin blood and prevent clotting. This improves circulation and prevents tissue death. The leeches leave behind small, Y-shaped wounds that usually heal without leaving a scar.

Leeches are effective at increasing blood circulation and breaking up blood clots. It should be no surprise that they can be used to treat circulatory disorders and cardiovascular disease.

Chemicals derived from leech saliva have been made into pharmaceutical drugs that can treat:

         hypertension

         varicose veins

         hemorrhoids

         skin problems

         arthritis

         acne

         hairs problems
