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’re 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.
Medicinal leeches have three jaws with tiny rows of teeth. They pierce a person’s 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.
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:
- varicose veins
- skin problems
People with heart disease use leech therapy because of
Cancer treatments using leech therapy are being
The progression of diabetes can cause numerous problems. These problems can lead to vessel diseases that limit or prevent blood from reaching the toes, fingers, hands, and feet. When blood flow becomes severely restricted, the affected tissue can die. This is the leading cause of amputation among people with diabetes. Losing a digit or limb due to complications from diabetes is a major concern for millions of people worldwide.
The most effective way to stop this process is to increase circulation to the affected tissues without the risk of blood clots.
The Hirudin substance in leech saliva thins the blood and keeps it from clotting. Since people with diabetes tend to have thicker blood, Hirudin can help relieve the pressure on the heart and cardiovascular system by thinning the blood. Researchers have

Leech therapy’s effect on blood clotting during and after these surgeries helps the body to heal more naturally and completely.
Leech therapy’s benefits for blood circulation has also led some people use leech therapy to treat baldness and hair loss on the scalp.
Leech therapy is both easy and has a lower risk of side effects than other therapies. However, there are some risks. There’s a
If something goes wrong after a round of leech therapy, blood will ooze out of the area that has been treated and the site of the leech bite will not close. Sometimes leeches will try to move to another area of the body where you do not need treatment, causing unnecessary blood loss. On occasion, a person will discover during or after leech therapy that they are allergic to leech saliva. If complications such as these occur, you will know right away and will no longer be a candidate for this treatment method.
It makes some people squeamish to imagine leeches being used as a modern medical treatment. But more and more research is showing that there’s a reason why leeches were relied upon for centuries as an essential part of medical care. As we continue to find out more about the special properties in leech saliva, it may very well be that the treatment has even more practical use than we would have ever thought possible.
