Leech therapy, also known as hirudotherapy, is an alternative medical treatment that involves the use of
leeches to draw blood from a patient's body. This practice has been used for centuries in various cultures around the world, with historical records dating back thousands of years.
The therapeutic use of leeches is based on the belief that their saliva contains various bioactive substances with medicinal properties. 
These substances include anticoagulants, vasodilators, and anti-inflammatory compounds. Leech saliva also contains hirudin, an enzyme that prevents blood clotting, which allows the leech to feed on blood for an extended period.
Leech therapy is often used to treat conditions such as:
- Venous congestion: Leeches can help improve blood flow in congested areas by removing stagnant blood and promoting circulation.
- Hematomas and bruises: The anticoagulant properties of leech saliva can help reduce blood clotting and alleviate swelling and bruising.
- Arthritis and joint pain: Some proponents believe that leech therapy can help reduce inflammation and pain in arthritic joints.
- Varicose veins: Leech therapy may be used to alleviate symptoms associated with varicose veins, such as pain and swelling.
During a leech therapy session, the leeches are typically applied to the skin near the affected area. As they attach and begin to feed, they release their saliva, which contains the therapeutic compounds. A single leech may feed for up to 30 minutes to an hour before detaching on its own. After the leeches have finished feeding, they are carefully removed from the skin, and the wound is dressed to control bleeding.
Before undergoing leech therapy or any alternative medical treatment, we give a consult with a qualified healthcare professional to discuss the potential risks and benefits and to ensure that it is safe and appropriate for your individual circumstances.
