Zhang Zhongjing was a prominent physician in ancient China, often regarded as the “Sage of Medicine.” He lived during the Han Dynasty and is best known for his work Shang Han Lun (Treatise on Cold Damage) and Jin Gui Yao Lue (Essential Prescriptions of the Golden Cabinet). Zhang pioneered the concept of 辨證論治 (differentiating syndromes and treating accordingly), which focuses on diagnosing a patient based on their unique symptoms, constitution, and external conditions, rather than just the disease. His methods continue to influence modern Traditional Chinese Medicine (TCM) diagnosis and treatment. Dr. Man Herbal doctors are skilled in applying Zhang’s approach, offering personalized care tailored to each patient’s needs.
