Leech therapy, medically known as hirudotherapy, is a traditional and complementary medical practice that involves the controlled application of medicinal leeches to specific areas of the body. The potential effects of this method are mainly associated with bioactive substances released by leeches during blood suction, which may influence local circulation, clotting mechanisms, and inflammatory processes.
In Turkey, leech therapy is regulated as a traditional and complementary medicine practice and should be performed in authorized centers by certified physicians.
In medical leech therapy, leeches collected from nature should not be used. Instead, medicinal leeches produced under controlled conditions must be preferred. The application area is determined by a physician, the skin is prepared appropriately, and the leeches are placed on the selected area.
The number of leeches, duration of application, and session intervals may vary from person to person. For this reason, leech therapy should not be considered a standard procedure for everyone. It should be planned according to the patient’s general health status, medical history, and current medications.
Medicinal leeches release various bioactive substances through their saliva while feeding. These substances may include compounds that affect blood clotting, support local blood flow, and contribute to microcirculation. Because of these effects, leech therapy may be considered in selected cases to support circulation, reduce local congestion, or assist tissue recovery.
In modern medicine, medicinal leeches are particularly recognized as an adjunctive option in cases of venous congestion, where venous blood flow is insufficient and tissue healing may be delayed. The FDA classification describes medicinal leeches as an adjunct to graft tissue healing when venous congestion may delay healing.
Leech therapy may be evaluated as a supportive method in selected cases involving circulation problems, localized swelling, some musculoskeletal complaints, chronic pain-related conditions, and certain tissue healing processes. However, it should not be presented as a guaranteed treatment for every disease.
It should not replace standard medical treatment. When appropriate, it may be considered as a complementary approach under medical supervision.
No. Leech therapy should not be performed at home, by unauthorized individuals, or with leeches obtained from uncontrolled sources. Using non-medical or wild leeches may increase the risk of infection, prolonged bleeding, tissue damage, and other complications.
For safe practice, the procedure should be performed in authorized medical settings by trained healthcare professionals.
Leech therapy may not be suitable for everyone and may carry certain risks. Possible complications include prolonged bleeding, infection, allergic reactions, scarring at the application site, and anemia due to blood loss. Medical literature reports that blood loss during leech therapy may sometimes lead to anemia and may require close monitoring.
People using blood thinners, individuals with bleeding disorders, severe anemia, suppressed immune systems, pregnancy, or active infections may not be suitable candidates. A detailed medical evaluation is necessary before the procedure.
Leech therapy is a complementary medical practice that uses medicinal leeches under controlled conditions. Although its supportive effects on local circulation, swelling, clotting processes, and tissue healing are being studied, it is not suitable for everyone and should not be described as a guaranteed treatment.
For safe and appropriate use, leech therapy should be performed by certified professionals after an individualized medical assessment.
