Raktamokshana (Therapeutic Bloodletting)
Raktamokshana is the fifth classical Panchakarma procedure: the controlled removal of a small amount of blood to treat conditions that Ayurveda links to impure or aggravated blood (Rakta), often with Pitta involvement. It is used selectively and only after careful assessment. The best-known method today is leech therapy (Jalaukavacharana); another is venesection (Siravedha).

How It Is Done
For leech therapy, a medicinal leech is applied to the affected area after cleaning. It feeds for a short time and detaches naturally; the small wound is then dressed. Each leech is used for one patient only. Treatment needs strict hygiene, monitoring of bleeding and wound care afterwards.
Whether Raktamokshana is carried out at the clinic or arranged by referral will be explained by the doctor during consultation.
What the Evidence Shows
Leech therapy is attracting growing research interest worldwide [4]. Small clinical studies in eczema [1] and knee osteoarthritis [2] reported benefit, but they were small, mostly without control groups, and much of the remaining evidence consists of single case reports. We therefore treat Raktamokshana as a specialised option for carefully selected cases, not a routine treatment.
