Treatment or therapy using blood, blood products, or blood-related substances, such as blood transfusions or plasma therapy.
From Greek 'hema' (blood) + 'therapeia' (treatment), describing medical practices that use blood or its components as therapeutic agents.
Blood transfusions were revolutionary—Karl Landsteiner's 1901 discovery of blood types turned blood from a poison (transfusions used to kill people) into one of medicine's greatest weapons, saving millions of lives.
