The Environmental Theory School, founded by the late Master Yuan Zhikui, represents a revolutionary approach to understanding and treating blood diseases through TCM. This theory views blood diseases as disorders of the body internal environment rather than isolated organ failures.

Building on this foundation, Director Yuan Jianzhang developed the Three-Level Internal Environment Full-Balance Blood Generation Method, which has shown remarkable clinical results in treating leukemia, aplastic anemia, ITP, and MDS.
