Dr.He's bloodletting therapy utilizing three edged needles is one of his "three adjusting methods of acupuncture". During his 70 years of clinical practice, he developed the theory that most diseases are caused by qi stagnation, and in order to restore qi circulation one needs to improve the blood circulation first. Based on this theory, in combination with empirical insights from clinical practice, he has developed a unique technique for using three-edged needles. He has also categorized and extended the application of bloodletting therapy with three edged needles to cover over 150 diseases. In addition, Dr. He's bloodletting therapy with three edged needles is an innovation that may inspire other physicians to develope and expand the use of acupuncture-related therapies to treat disease.
