Principles of Lee Je-ma’s Sasang Medicine & 8-Constitution Theory
Established by scholar Lee Je-ma in Donguisusebowon (1894), Sasang Constitutional Medicine classifies human physiology into four core types—Tae-Yang, So-Yang, Tae-Eum, and So-Eum—based on the congenital strength asymmetry of the Lungs, Spleen, Liver, and Kidneys. Later expanded by Dr. Kuon Dowon into 8 Constitutions, it provides a precision blueprint for diet, exercise, and stress management.
