PRP therapy, which is short for platelet-rich plasma therapy, is becoming popular as a natural way to treat a variety of conditions in humans today. As an integral component of blood, plasma’s function is of “healing” through its protein contents. In addition to giving blood its clotting characteristic, it promotes cell growth in the body too. As part of the PRP therapy, your blood is drawn and the platelet rich plasma component which includes cytokines and growth factors is isolated.
