The invention discloses a high blood pressure therapy machine with pressure waves. The high blood pressure therapy machine mainly comprises a pressure wave generating device, wherein in a liquid medium, high voltage electropulse is released and generates the pressure waves which focus on certain portions of the limbs or acupoints, and the pressure wave generating device is selected from one of an electromagnetic effect pressure wave pulse generating device body, a hydroelectric effect pressure wave pulse generating device body and a piezoelectric effect pressure wave pulse generating device body. According to the high blood pressure therapy machine, the pressure waves are utilized to stimulate certain portions of the limbs or acupoints, so that the blood circulating system of the human tissues is affected, high blood pressure is lowered or made to reach the normal value, a patient reduces the dosage of hypotensive drugs or maintains a normal blood pressure without taking medicine for a long time, and thus the purpose of treatment is achieved.
