Ching Dynasty
Yu, in the Qing Dynasty, wrote An Outbreak. On the basis of Wu Youke's Treatise on Febrile Diseases, he thinks that boils are the cause of boils, and points out that "if one person gets sick, it will infect one family, and if it is light, ten cases will be born, and if it is serious, one or two cases will be saved." According to the characteristics of diseases and syndromes of summer plague, the prescription of "Qingwen Baidu Drink" with gypsum as the main ingredient was established, which created a new situation for the syndrome differentiation and treatment of summer plague.
To sum up, Chinese medicine has accumulated rich experience in the long-term struggle against epidemic febrile diseases and has a relatively complete set of theoretical and clinical treatment methods. We should give full play to the role of traditional Chinese medicine in treating acute infectious diseases.
