Our Founder

Born in Luzhou, China, Dr. Chen Guoyi has dedicated his life to “Mastering of Great Skills to Alleviate the Suffering of Patients”. It is this dedication that drove Dr. Chen to create his unique treatment methods for Piles and Fistula called Guoyi Proctology Therapy. In 1979, he moved to Xi’an and established the first Piles and Fistula hospital in the region.

Word of mouth spread quickly and by 1980, Dr. Chen had successfully cured tens of thousands of patients. He was later presented with the award of excellence in Medical Technology and Development by the government of Xi’an.

From these humble beginnings, Dr. Chen has established himself as a preeminent expert in the field, having served as Director of Piles and Fistula at Beijing Chinese Medicine University, as well as Chief Physician of China Oriental Hospital. His techniques and treatments have been introduced throughout the world, including Columbia University in New York.

In recent years, Dr. Chen has been invited to give lectures in Hong Kong, Singapore, Spain, Canada, and the United States on the topic of promoting Traditional Chinese Medicine worldwide.

Founded by Dr. Chen Guoyi, a fourth-generation doctor in a highly esteemed, medically focused Chinese family, he has dedicated his life to mastering the skills to heal and alleviate his patients’ pain and suffering through the Guoyi Proctology Therapy and his exclusive Ba Zhi San ointment. The methodology of our hemorrhoids treatment is through naturopathic medicine. Our body has self and natural healing functions, and based on each patient’s unique symptoms, we may apply minor surgical treatment and Ba Zhi San as part of your therapy plan.

Minor Surgical Treatment
If your hemorrhoids prolapse for a long period of time and cannot be reinserted into your anus manually, you may experience a burning sensation or pain when defecating. If you are experiencing these symptoms, it is likely caused by hemorrhoids, varicose veins, blood hemorrhaging, thrombosis, and/or restricted tissue circulation.
