Jalauka (leech therapy) and Siravedha (Siravyadha) are two classical Raktamokshana (bloodletting) therapies in Ayurveda that help eliminate vitiated blood (Dushta Rakta).

Siravyadha (also called Siravedhana) is a classical Ayurvedic para-surgical therapy that involves carefully puncturing a vein to remove vitiated or impure blood.
