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

Upon graduating from Shanghai Second Medical University in 1962, Dr. Zhang commenced his career as a physician at The Reijing Hospital of Shanghai Second Medical University. His dedication to merging the most effective aspects of Traditional Chinese Medicine (TCM) with modern medical practices became the cornerstone of his clinical endeavors and research, aiming to optimize both clinical efficacy and the quality of life for his patients.

In 1980, he earned a prestigious World Health Organization scholarship, which facilitated a two-year fellowship at Harvard Medical School and Massachusetts General Hospital, further enriching his medical expertise.

In 1991, Dr. Zhang established the Zhang Clinic in New York City, primarily dedicating his efforts to treating opportunistic infections in HIV/AIDS patients, a period when effective antiretroviral therapies were not yet available. Through the utilization of Allitridi, the precursor to Allicin, and other broad-spectrum antimicrobial compounds, Dr. Zhang significantly extended the lives and enhanced the quality of life for his patients.

In recent years, Dr. Zhang has redirected his focus toward employing these potent antimicrobial compounds to address a variety of chronic infections, with a particular emphasis on tick-borne illnesses. This shift underscores his commitment to adapting to evolving medical challenges and continuing to provide innovative and effective care to his patients.
