Hypertension can be treated by bloodletting therapy. The main treatment of hypertension through bloodletting therapy is to take bloodletting therapy at the ear tip, which is to release the right amount of blood by puncturing the ear tip point with blood collection needles to treat and relieve hypertension. The efficacy of ear tip bloodletting therapy is to eliminate wind and heat, clear the brain and brighten the eyes, relieve pain and lower blood pressure, which is simple to operate and has more precise efficacy without obvious side effects, and is widely used in clinical practice. Hypertension bloodletting therapy is to lower blood pressure to a certain extent by bleeding the appropriate acupuncture points. However, the cause of hypertension is complex, and bloodletting therapy can only temporarily relieve the symptoms caused by hypertension, but cannot completely cure hypertension. Bloodletting therapy for hypertension is suitable for ages ranging from 10 to over 70 years old, and the suitable patient group generally does not exceed hypertension level 2. From a TCM perspective, patients with hyperactive liver yang type hypertension are more suitable.
