Dr. Qingcai Zhang
Clinic Founder, Developer of Zhang Protocol Formulas

Upon graduation from Shanghai Second Medical University in 1962, Dr.Zhang worked as a physician and orthopedic surgeon at The Reijing Hospital of Shanghai Second Medical University. Thereafter, his clinical work and research focused on combining the most effective parts of TCM and modern medicine to maximize clinical efficacy and quality of life for the patient. 

In 1980, he was awarded a World Health Organization scholarship which resulted in a two-year fellowship at Harvard Medical School and Massachusetts General Hospital.​

In 1991, Dr.Zhang founded the Zhang
Clinic in New York City. At that time, he was primarily focused on using Allitridi, the chemical pre-cursor to Allicin, and other anti-microbial compounds to combat difficult-to-treat infections. 

After decades of clinical research and experience, he began to consolidate the information and created the core formulas that are used at the Zhang Clinic.
