LU Yuan-lei (1894 - 1955) is the representative of Chinese and Western Medicine Convergence School in modern times. He is also the advocate of scientization of Traditional Chinese Medicine (TCM). TCM scientization is the refleetion of influence of Kampo medicine in modern China. Many academic viewpoints of LU Yuan-lei such as disease are caused by poison, scientifically elaborate ZHANG Zhong-jing's theories; thought on diseases not cured unless the medicine causes Mingxuan (a type of reaction in treatment'); the six meridians in Shanghanlun are not meridians in acupuncture; the value of pulse diagnosis and the sense of theory of 'Wu Yun Liu Qi' are influenced by Japanese Kampo medicine.
