PRP or platelet-rich plasma is a substance which helps in healing when injected. Plasma is that component of the blood which helps to form the clot when there is a cut. Plasma also consists of proteins which help in the growth of cells. PRP has been produced by the researchers by separating plasma from blood and then concentrating it.
The concept behind PRP is that, injecting PRP into the tissues which are damaged and helping the body to grow new healthy cells and also to promote the healing of the damaged cells.
