2 Traditional Chinese Medicine’s Understanding of the Pathogenesis of Scarlet Fever

Scarlet fever falls under the category of warm diseases in traditional Chinese medicine—a very ancient disease with early records in Chinese medical literature, yet it long remained difficult to distinguish from other rash-causing illnesses. As early as the Golden Cabinet Essentials and the Standard of Cold Damage, it was referred to as "yang poison," suggesting that this was one of the earliest descriptions of the disease. For example, Zhang Zhongjing’s Golden Cabinet Essentials recorded: "Yang poison manifests as redness of the face, with spots resembling soft patterns. Sore throat, with pus and blood discharge...". Although the disease was not named specifically, its clinical manifestations closely resembled this disease. Medical practitioners of the Tang, Song, and Ming dynasties also documented the clinical presentation and treatment of this disease, though these records were scattered. It wasn’t until the Qing dynasty, as warm disease theory advanced rapidly, that detailed accounts began to emerge. For instance, the Qing Dynasty’s… ·“Secret Methods for Treating Rotten Throat,” stated: “There is a condition called rotten throat, which arises in winter and spring, affecting both young and old alike; when it occurs, patients experience high fever, intense thirst, thick redness of the muscles, resembling soft patterns, sore throat, and a mass of painful inflammation—internal heat is intense.” This description closely resembles scarlet fever, and it highlighted the disease’s strong contagious nature. For example, Chen Gengdao’s “Herbal Remedies for Epidemic Throat” stated: “The poison of epidemic throat can be contracted through contact, or transmitted through the air… Those who absorb the poison through the mouth and nose contract it, while those who inhale the poison from an infected person transmit it through household contact.” This passage explained that the disease originates when pathogenic toxins enter the body through the mouth and nose, accumulate in the throat, and when climatic conditions are cold or unbalanced, when the body’s vital energy is depleted while pathogenic forces are strong, the toxins rapidly transform, leading to high fever, irritability, delirium, and widespread scarlet rashes across the body. After the mid-Qing dynasty, this disease became increasingly prevalent, allowing medical practitioners to accumulate rich clinical experience and write numerous specialized treatises, such as Jin Dejian’s “Essentials of Rotten Throat and Diarrhea,” Chen Gengdao’s “Herbal Remedies for Epidemic Throat,” and Cao Xinyi’s “Correct Understanding of Throat Disease,” all of which made significant contributions to the diagnosis and treatment of this disease.

(2) Traditional Chinese Medicine’s Understanding of the Pathogenesis of Scarlet Fever Exogenous warm and epidemic toxins are the primary causes of scarlet fever. When climatic conditions are cold or unbalanced, and the body’s vital energy is deficient, this disease is triggered.
