Shang Han Lun

The Shang Han Lun is an ancient Chinese medical text, dating back to around 200 AD, that offers a systematic approach to diagnosing and treating illnesses caused by external cold and pathogenic influences. It organizes symptoms into specific patterns, helping practitioners identify which organ systems are affected and prescribe appropriate herbal remedies, acupuncture, or other therapies. The book emphasizes understanding the balance of Yin and Yang, the body's vital energies, to restore health. It remains a foundational work in traditional Chinese medicine, guiding practitioners in applying a holistic, pattern-based approach to health and disease.
