Leech Therapy or Jalaukavacharana is an ancient Ayurvedic treatment method used for bloodletting, which involves the application of medicinal leeches (Hirudo) to the skin. This therapy is primarily used to remove impure blood from the body, treat various conditions, and promote overall healing. In modern terms, this is referred to as Hirudo Therapy and is recognized for its effectiveness in treating a range of diseases, especially those related to blood and inflammation.

Historical Background of Leech Therapy in Ayurveda
In Sushruta Samhita, one of the foundational texts of Ayurveda, Jalaukavacharana is categorized as a part of Raktamokshana, or bloodletting therapy, and is highly recommended for treating ailments caused by the imbalance of Pitta dosha. Bloodletting, including leech therapy, was traditionally used to detoxify the blood and restore balance in the body.
Principles of Leech Therapy in Ayurveda
According to Ayurveda, many diseases arise from an imbalance of the three doshas: Vata, Pitta, and Kapha. Leech therapy is particularly effective in conditions caused by Pitta and Kapha dosha imbalances, which often manifest as inflammation, heat, and toxin accumulation. By removing impure blood, leeches help restore balance and reduce symptoms of various ailments.

How Leech Therapy Works
Medicinal leeches are carefully placed on specific parts of the body where the condition is most severe. Leeches secrete a variety of bioactive substances that not only help to thin the blood but also promote healing. Some of the beneficial enzymes and compounds secreted include:
1. Hirudin: An anticoagulant that prevents blood clotting, allowing the leech to remove blood continuously without the formation of clots.
2. Calin: Inhibits platelet aggregation, preventing blood clotting for a certain period even after the leech has detached.
3. Bdellins and Eglins: These are anti-inflammatory proteins that help reduce inflammation.
4. Hyaluronidase: An enzyme that increases tissue permeability, allowing better blood flow and the distribution of therapeutic substances.
5. Anesthetics: Leeches secrete anesthetics, which make the bite almost painless.

Procedure of Leech Therapy in Ayurveda
1. Selection of Leech: Medicinal leeches (Jalauka) are carefully chosen for their healing properties. Ayurvedic texts suggest the use of non-poisonous leeches, specifically selected for their effectiveness in medical treatment.
2. Preparation of the Patient: The affected area is cleaned and sometimes massaged to encourage blood flow to the region.
3. Application of the Leech: Leeches are placed on the desired area, where they attach themselves and start to suck blood. This process is generally painless due to the anesthetic substances secreted by the leech.
4. Duration of Treatment: The leech feeds for about 20–45 minutes, during which it extracts a small amount of blood. Once it has consumed enough, it will naturally detach from the skin. If it doesn’t, it can be carefully removed with the help of turmeric or saline solution.
5. Post-Treatment Care: After the leech detaches, the wound is cleaned and bandaged. The area may bleed for a few hours after the therapy, but this is a natural part of the treatment process and helps detoxify the body.

Benefits of Leech Therapy (Jalaukavacharana)
Detoxification: Helps in the removal of impure blood and toxins, improving the overall health of the body.
Anti-inflammatory: Reduces swelling and inflammation in affected areas.
Pain Relief: Due to the anesthetic properties of the leech's saliva, the therapy is relatively pain-free, and its anti-inflammatory compounds help in reducing pain.
Improved Circulation: Leech therapy helps in increasing blood flow to areas with poor circulation, promoting healing and regeneration of tissues.
Antimicrobial Effect: The antibacterial enzymes in the leech's saliva aid in preventing infections, making it especially useful for chronic wounds and ulcers.
Non-Invasive: It is a natural, non-invasive treatment that avoids the need for surgery in many cases.
