Raktamokshana — Bloodletting
Raktamokshana is the fifth Panchakarma procedure — the only one of the five that is more thoroughly documented in Sushruta Samhita (the surgical tradition) than in Charaka Samhita. It involves the removal of vitiated Rakta (blood carrying excess Pitta or toxins) from specific locations. Among the four classical methods, Jalaukavacharana (leech therapy) is the most commonly practised in modern clinical settings and has the most contemporary research documentation.
The four classical methods
Siravyadha (venipuncture): Controlled phlebotomy at specific Sira (veins) documented in Sushruta Samhita. Sushruta documents 700 Sira in the body, of which specific ones are therapeutic access points for different conditions. The volumes removed, specific veins used, and conditions treated are all documented. This method is rarely performed in modern practice outside specialised Sushruta Tantra (surgical Ayurveda) clinics.
Pracchana (superficial scarification): Multiple fine superficial incisions over the affected area to produce localised bleeding. Documented for localised Pitta-Rakta conditions — specific skin conditions, localised inflammation, and venous stasis conditions. Performed under full sterile conditions.
Jalaukavacharana (leech therapy): Application of medicinal leeches (Hirudo medicinalis or Hirudo verbana) to specific locations. The most widely practised modern method. The leech produces controlled local bleeding while simultaneously injecting hirudin (anticoagulant), hyaluronidase, and other salivary compounds. This is the method with the most modern research documentation.
Shringa (horn cupping / dry cupping): Application of horn or modern cupping devices to produce local suction and drawing of blood or fluids toward the surface. Documented for localised Vata-Rakta and Kapha-Rakta conditions where direct bloodletting is not indicated.
Jalaukavacharana in detail
Pitta-Rakta conditions
Sushruta Samhita documents Jalaukavacharana for: varicose veins and venous stasis, specific skin conditions (eczema, psoriasis-type Pittaja Kushtha, localised inflammatory lesions), chronic non-healing wounds, Vatarakta (gout-type conditions), and certain eye conditions. Modern research has also documented leech therapy for post-operative tissue flap survival and for specific thrombotic conditions — consistent with the classical Pitta-Rakta indications.
Leech application protocol
The body area is cleaned without antiseptics (which repel leeches). Leeches are applied to the specific location documented in the classical or modern protocol. They attach and feed for 20–45 minutes until satiated, at which point they release spontaneously. A small persistent bleeding from the wound site is normal and expected — the hirudin prevents coagulation for 6–12 hours. The site is managed with pressure and monitoring.
