The understanding and treatment of warm disease by Lu Jiuzhi of the Qing Dynasty and the modern Zhang Xichun both followed the treatment methods for yangming disease in the "Treatise on Cold Damage Diseases." Lu believed that "yangming is the source of warm disease," while Zhang's basic attitude towards the theories of Weiqi nutrient-blood and the triple energizer was one of rejection. Of course, their understanding may not necessarily be correct, as they did not see that the study of warm and heat diseases was an inheritance and development of Zhongjing's teachings. However, in terms of clinical experience, Lu was adept at using Gardenia, Fermented Soybean, and Rhubarb Rhizoma, while Zhang was renowned for his skillful use of White Tiger Decoction. He derived five variations from the White Tiger Decoction, including the Zhenni White Tiger Decoction, Xianlu Decoction, Hanjie Decoction, Liangjie Decoction, and Hejie Decoction, each with its own specific application, clearly structured, and uniquely crafted. In 1959, Dr. Guo Keming from Shijiazhuang, Hebei, used Zhang Xichun's method to treat encephalitis B with White Tiger Decoction. Guo Keming was a disciple of Zhang.
