Input: Suo. The pathogenic toxin of scarlet fever is inhaled through the mouth and nose, causing damage to the lungs and stomach. When the heat becomes severe and the toxin is intense, it immediately transforms into heat and fire within the body. The throat serves as the gateway between the lungs and stomach; when the toxin and fire surge upward into the throat, redness, swelling, and burning pain occur, leading to tissue decay and pus formation—this is what is known as “when heat is excessive, swelling occurs; when toxin is severe, corruption leads to ulceration.” The lungs govern the skin and hair, while the stomach controls the muscles; when warm, toxic pathogens accumulate in the lungs and stomach and spread outward to the skin, they manifest as scarlet rash, spreading across the entire surface of the body like fine threads. This disease progresses along the Wei, Qi, Ying, and Xue pathways. In the early stages, symptoms often present as manifestations of the lung-Wei system, though these symptoms are typically short-lived. As the pathogenic toxin moves from the exterior to the interior, it transforms into dryness and fire, filling the Qi and Ying channels, potentially leading to severe conditions characterized by both Qi and Ying being burned. For those with inherently weak vital energy, the pathogenic toxin may penetrate inward to the Jueyin, causing heart fire to become excessively heated, liver wind to stir, and the combination of wind and fire to exacerbate the condition, resulting in high fever, delirium, and convulsions. If blood heat is severe, it can lead to abnormal blood flow, causing purplish-red rashes or petechial hemorrhages, and even creating a dangerous situation where internal obstruction leads to external collapse. In the later stages of the disease, heat consumes yin fluids, causing damage to the yin of the lungs and stomach, shifting from excess to deficiency; when heat and toxin affect the heart, they may spread to the joints, or damage the water metabolism functions of the lungs, spleen, stomach, and kidneys, leading to various complications. (3) TCM Differentiation and Classification of Symptoms and Treatment Methods

1. Pathogen in the Lung-Wei Region The primary symptoms include sudden onset of illness, fever, headache, chills, redness and swelling of the throat, severe cases leading to ulceration, nausea and vomiting, sparse rash, a red tongue, a thin white or yellow coating on the tongue, a floating, rapid, and forceful pulse. Treatment focuses on clearing heat, relieving throat inflammation, and detoxifying the body, using a modified Yin Qiao San formula: 20g of Lonicera japonica flower, 20g of Forsythia suspensa, 10g of Radix Paeoniae Alba, 10g of Platycodon grandiflorus, 10g of Bupleurum chinense, 6g of Licorice root, 10g of Flos Sophorae, 10g of Herba Schizonepetae, 9g of Radix Paeoniae Rubra, 30g of Herba Lysimachiae. The herbs are decocted in water and taken once daily.
2. Pathogen Entering the Qi and Ying Channels The primary symptoms include high fever, irritability, thirst, and extreme throat congestion; the tonsils are red and swollen, with white exudate, and the rash is widespread and scarlet in color. The tongue is red and dark, with papillae resembling bayberries, the tongue coating is yellowish and rough, eventually peeling off, and the pulse is full and rapid. Treatment should focus on clearing the Qi and cooling the Ying, clearing heat and detoxifying the body, using a modified Qingwen Baidu Yin formula: 30g each of Radix Isatidis, Fresh Rehmannia Root, 20g of Gypsum, 9g of Cortex Phellodendri, 9g of Radix Paeoniae Rubra, 9g of Anemarrhena Asphodeloides, 10g of Scutellaria Baicalensis, 9g of Phyllostachys Nigra, 5g of Platycodon Grandiflorus, 4.5g of Licorice root, and 3g of Coptis Chinensis. The herbs are decocted in water and taken once daily.
3. Pathogen Toxicity Penetrating Deeply: The primary symptoms include high fever, irritability, coma, delirium, convulsions, purplish-red rashes or petechial hemorrhages, a red and dark tongue, and a fine, rapid pulse. Treatment should focus on clearing the Ying and cooling the Blood, calming the mind and extinguishing the Wind, using a modified Qingying Tang formula: 10g of Rhinoceros Horn, 30g of Fresh Rehmannia Root, 30g of Purple Herb, 9g of Lonicera japonica flower, 9g of Forsythia suspensa, 9g each of Cortex Phellodendri and Radix Paeoniae Rubra, 3g of Coptis Chinensis, 9g of Phyllostachys Nigra. The herbs are decocted in water and taken once daily.
4. Remaining Toxins Still Present: The primary symptoms include fever, palpitations, chest tightness, fatigue, excessive sweating, joint pain, a thin tongue coating, and a rapid, weak, or irregular pulse. Treatment should focus on replenishing Qi, nourishing Blood, and calming the Heart, using a modified Zhigan Tang formula: 15g of Licorice root, 10g of Ginseng, 10g of Angelica sinensis, 15g of Salvia miltiorrhiza, 12g of Rehmannia root, 15g of Mai Dong, 10g of Dendrobium officinale, 10g of Schisandra chinensis, 10g of Ziziphus jujuba seeds, and 5g of Cinnamomum cassia. The herbs are decocted in water and taken once daily.
5. Yin Deficiency in the Lungs and Stomach: The primary symptoms include loss of appetite, fatigue, dry lips and mouth, or dry cough, flaky skin, a red tongue with little saliva, and a fine, rapid pulse. Treatment should focus on nourishing Yin and generating Fluids, clearing Heat and moistening the throat, using a modified Shangbiao Dong Tang formula: 20g of Saishen, 10g of Tian Dong, 15g of Mai Dong, 15g of Dendrobium officinale, 15g of Radix Paeoniae Rubra, 10g of Platycodon grandiflorus, 6g of Licorice root, 10g of Reed Root. The herbs are decocted in water and taken once daily. If the patient is irritable and restless, or if the tongue is red and covered with papillae, add 10g of Bamboo Leaf, 9g each of Radix Paeoniae Rubra and Radix Scutellaria; for patients with dry throat and a desire to drink, add 12g of Honeysuckle Flower and Dendrobium officinale; for constipation, add 9g each of Rheum palmatum and Radix Scutellaria; for high fever and delirium, administer An Gong Niu Huang Wan. (4) TCM Resources on Differentiation and Treatment of This Disease In modern times, Ding Ganren had extensive experience in treating scarlet fever, which is described below:
6. Sweat-Inducing Therapy (in four steps): ① The Jie Ji Tu Sha Tang was specifically used for early-stage scarlet fever, treating symptoms such as chills and fever, redness and swelling of the throat, body aches, and discomfort accompanied by nausea and vomiting. ② The Ma Xing Shi Gan Tang was adapted for cases where the scarlet fever did not fully resolve, presenting with cold chills and fever, white or foul discharge in the throat, or severe cough with reversed qi. ③ The Jia Jian Ge Gen Sheng Ma Tang was used for cases where the scarlet fever was widespread but only the head and face were affected, with fever and no sweat. ④ The Bai Du San was used for cases where the scarlet fever had not yet fully resolved, leaving behind scarlet toxins, swelling, hardness, and pain, with fever and no sweat. 2. Clearing Therapy (also in four steps): ① The Jia Jian Hei Gao Tang was used for cases where the pathogenic toxin did not reach the target area, consuming and drying up fluids, leaving the scarlet fever widespread but without resolution, with fever and no sweat, redness and swelling of the throat, white discharge, and thirst and irritability. ② The Liang Ying Qing Qi Tang was used for cases where the scarlet fever was widespread, accompanied by high fever, thirst, and a desire to drink, even leading to delirium and verbal hallucinations, with swelling and redness of the throat, white discharge, a rapid pulse, and a red or dark, lacking moisture tongue. ③ The Jia Jian Zi Yin Qing Fei Tang was used for cases where the scarlet fever was accompanied by internal and external rotting in the throat, with fever and yellow coating on the tongue, or a red and dark tongue that could not be opened for release. ④ The Jia Jian Zhu Ye Shi Gao Tang was used for cases after the scarlet fever had subsided, with persistent fever, thirst, or sore throat, a feeling of heaviness in the throat, and excessive phlegm and cough. 3. Detoxification Therapy (also in four steps): Either use large amounts of bitter and cold herbs to directly induce diarrhea, or combine them with saltpeter and bitter herbs to clear heat and cool the body, or use the Liang Ge San to treat the exterior and attack the interior, or use Chen Jin Jiang to clear the exterior and act on the interior. Alternatively, use the Lian Jin Zhi to clear the exterior and the interior. In addition to medicinal treatments, there are also external therapies that can complement oral medications. ① For severe throat swelling, slice White Edge Yunnan Green Root and hold it in the mouth (with strong cardiac and detoxifying effects). ② Crush garlic and soybeans into a paste, wrap it around the tiger's mouth area about two inches away from the wrist bone, and let the bubbles form in the paste; squeeze out the liquid from the bubbles and apply the paste, ensuring it does not come into contact with dirt. ③ Use Gold Not Replace to blow into the throat (add three qian of White Yunnan Green, three qian of Jade Key, finely ground and blown into the throat). ④ Use the Thirteen Treasure Powder to blow into the throat, adding Western Yellow Cattle Horn, large Motherwort (remove the core), and Bupleurum, each with three qian; calcine the human middle white, grind white amber into fish bile (large ones dried in the sun, or use three dried green fruit cores as substitutes for charcoal). Add five qian of large pearls (boil them inside tofu to remove oil and grind them separately). Do not overuse for cases of ulcerated lesions. Add four qian each of Borax and human fingernails (both sides, though they may be difficult to see when roasted for a moment, use four qian of Calcined Dragon Bone instead). Grind all ingredients into a fine powder, specifically for treating all cases—whether already ulcerated or not—those with redness and swelling in the throat, as well as cases of poison-induced acne, post-disease tooth decay, and post-scarlet fever poisoning in the throat, to reduce swelling, relieve pain, and promote healing of the affected areas. Old Chinese medicine practitioner Ren Yingqiu at Beijing College of Traditional Chinese Medicine provided detailed descriptions of scarlet fever classification and treatment: ① Preparatory Stage: Use the Jie Ji Tu Sha Tang for early-stage scarlet fever, treating symptoms such as chills, fever, throat swelling and pain, difficulty swallowing, and general body aches. Also treat symptoms like irritability and nausea. ② Rash Stage: Use the Qing Re and Tong Ran methods, treating cases where fever and throat pain persist, and redness and swelling appear throughout the body. ③ Desquamation Stage: Adjust the Sheng Ma Ge Gen Tang to treat cases where scarlet fever appears on the head, face, and nose, but without fever, diarrhea, or painful throat. ④ Liang Ying Qing Qi Tang: Specifically treats cases where scarlet fever is widespread, accompanied by high fever, irritability, thirst for cold drinks, even delirium and verbal hallucinations, with swelling and redness of the throat, a rapid pulse, and a red or dark tongue lacking moisture. Old doctor Chen Cunren treated scarlet fever using the first formula (days 1–3): Focus on inducing sweating and using the Jie Ji Tu Sha Tang. The second formula (day 4) emphasized clearing and resolving the disease, using the Qing Wen Baidu Yin formula. The third formula (days 4–5) was used for cases where scarlet fever worsened, employing the Xiang Jue Di Huang Tang. The fourth formula (after recovery) was the Sang Ju Yin formula. Yao Fengwu believed that scarlet fever belongs to the category of "warm-heat epidemics," and should be differentiated according to the patterns of Wei, Qi, Ying, and Xue. For mild cases, use the Yin Qiao Jie Du Tang with adjustments; for severe cases, use the Huang Lian Jie Du Tang with adjustments; for cases where heat and toxin have penetrated deeply, use the Qing Ying Tang with adjustments, taking An Gong Wan as a supplement. For cases where the rash does not fully resolve, use Gegen and Peppermint; for high fever, use Gypsum; for purple snow, use Danpi and Red Peony; for cases where scarlet fever is accompanied by deep purple and black rashes, use Danpi and Red Peony, along with Gegen and other herbs. For cases of pus and toxicity, use Lonicera japonica flower, Plantago major, Gentiana scabra, Wild Chrysanthemum, and Taraxacum mongolicum; for thirst, use Honeysuckle Flower; during the desquamation stage, use the Saishen Mai Dong Tang frequently. During the initial phase of scarlet fever treatment in Beijing, it is important to clear the lungs and protect the Wei, allowing the pathogenic toxin to move outward and enter the interior, spreading into the Qi and Ying channels. Treatment should focus on clearing heat and detoxifying, clearing both Qi and Ying, and transforming the Qi back into the Yang. If the toxin has penetrated into the Ying and Blood channels, then it is necessary to clear the Ying and cool the Blood, clearing heat and detoxifying. ① For cases where the pathogen resides in the Lung-Wei region, treat with pungent and cooling herbs to clear the pathogen and relieve throat inflammation, using the Yin Qiao San formula. ② For cases where the pathogen enters the Qi and Ying channels, treat with Qi and Ying cleansing, clearing heat and detoxifying, using the Qing Wen Baidu Yin formula. ③ For cases where the pathogen has entered the Ying and Blood channels, treat with clearing the Ying and cooling the Blood, clearing heat and detoxifying, using the Qing Ying Tang formula. ④ For cases where the pathogen has lingered in the Yin and damaged the body, treat with nourishing Yin and strengthening Qi, while also clearing residual toxins, using the Yu Jing Tang formula with additions. Single-herb remedies: ① 10g of Bupleurum chinense, 10g of Lonicera japonica flower, 15g of Radix Isatidis, ground into powder and taken orally. ② 15g each of Achyranthes bidentata and Radix Isatidis, decocted in water and taken. ③ 15g of Radix Isatidis, 30g of Lonicera japonica flower, 6g of Licorice root, decocted in water. ④ 15g of Andrographis paniculata, decocted in water. Wang Qin combined clinical presentations of scarlet fever with integrated Chinese and Western medicine to treat the disease. If a child suddenly develops fever, headache, chills, redness and swelling of the throat, severe cases leading to ulceration, nausea and vomiting, sparse rash, a red tongue, a thin white or yellow tongue coating, and a floating, rapid pulse, this indicates that the pathogenic toxin is present in the exterior. Treatment should focus on clearing heat and detoxifying the throat, using the Yin Qiao San formula. For cases where the pathogen enters the Qi and Ying channels, treat with Qi and Ying cleansing, clearing heat and detoxifying, using the Qing Wen Baidu Yin formula. For cases where the pathogen has entered the Ying and Blood channels, treat with clearing the Ying and cooling the Blood, clearing heat and detoxifying, using the Qing Ying Tang formula. For cases where the pathogen has lingered in the Yin and damaged the body, treat with nourishing Yin and strengthening Qi, while also clearing residual toxins, using the Yu Jing Tang formula with additions.
