Raktamokshana also called as blood letting therapy is one among the five chief purificatory methods of traditional ayurvedic panchakarma treatment method. Raktamokshana is a process done to expel the vitiated blood from the body which in turn removes the vitiated dosha in the blood. There are two main methods adopted traditionally to let out the blood from the body namely Jaluka vacharnam / Leech therapy - In this therapeutic procedure medicinal leeches are applied over the skin after choosing the suitable local area in the body. The blood is thus evacuated by the leeches. Siravedanam - Siravedanam is also a form of blood letting therapy done using catheters. A needle of a syring or a venflon is inserted into smalled blood vessels of the leg and regulated quantity of blood is let out to relieve sweeling and congestion in the legs. The procedure is chiefly employed in patients presenting with severe vericose veins.
