Healing properties of human blood have been known since ancient times. Consistent development of the blood doctrine and blood properties has contributed to emergence of cellular technologies, the absolutely unique trend in medicine. Plasma therapy is the integral part of cellular technologies. By means of injections with blood plasma enriched with platelets, we can achieve non-surgical regeneration of structure and function of the organs rich in connective tissue — skin, tendons, ligaments, cartilage, joints, etc. Plasma therapy can be considered as a totally biological technique, since blood for production of plasma is taken from the patient himself.
