Wang Shu-Ho [Wang Shuhe] is known for two major contributions. He recovered the first major herbal formulary, the Shang Han Lun (ca. 220 A.D.), by Chang Chung Ching [Zhang Zhongjing] , putting together the fragmentary record and arranging it in logical order. He set down the knowledge of pulse diagnosis in the book Mai Ching. Both books remained medical classics and were revived and revised during the Song Dynasty. Both books have been translated to English. Wang was also known for his expertise in dietary therapies. He cautioned about impure foods, overeating, excessive drinking, and the hazards of fried foods.
