Venesection
Definition:
Removal of approximately a pint of blood in a manner similar to that for donating blood. The procedure is generally used as a simple measure to reduce the number of circulating red blood cells (e.g., to treat polycythemia) or to reduce the amount of circulating iron (e.g., to treat hemochromatosis). The procedure may be repeated as needed.

It falls under procedures referred to as phlebotomy (removing blood for therapeutic or diagnostic purposes) or bloodletting (removing blood for therapeutic purposes).
