Traditional Chinese Medicine history time! Meet Dr. Zhang Zhong Jing. 📚
Zhang Zhong Jing, who lived during the Eastern Han Dynasty (around 150 to 219 CE), is regarded as one of the most important physicians in Chinese medical history. His work, Shang Han Za Bing Lun (Treatise on Cold Damage and Miscellaneous Diseases), was written during a time of social unrest and epidemic illness.
The text laid the foundation for understanding infectious and epidemic diseases in Chinese medicine. Zhang described how external pathogenic factors, especially Cold, could pe*****te the body in stages, progressing from the exterior to the interior. He identified six major stages of disease known as Taiyang, Yangming, Shaoyang, Taiyin, Shaoyin, and Jueyin, each with its own clinical presentation and corresponding treatment strategies.
Zhang’s herbal formulas were designed to match specific symptom patterns, a principle that remains at the core of modern herbal practice. Classic formulas such as Gui Zhi Tang for early stage febrile illness and Ma Huang Tang for exterior Cold are still prescribed today with little alteration!
After Zhang’s death, his work was divided and edited into two primary texts, the Shang Han Lun (Treatise on Cold Damage Disorders) and the Jin Gui Yao Lue (Essentials from the Golden Cabinet). Later scholars including Wang Shuhe, Lin Yi, and Cheng Wuji refined and expanded upon his theories, ensuring that Zhang’s methods continued to evolve within the broader framework of traditional medicine.
The Shang Han Lun remains one of the most studied and referenced works in Chinese medicine, serving as a bridge between early classical theories and the clinical traditions that followed.
