This is a unique remedy for the treatment of various diseases with the use of medical leeches, which are used in folk medicine. Leeches are grown under special biological conditions that ensure their sterility. Medical leeches can not transmit an infection to a patient, since each leech is used only once. In addition, they also have the ability to detect the disease and interact only with the actual damaged organs. Hirudotherapy often helps to avoid the need for surgical intervention, and sometimes it becomes the only hope for healing.
