Mumps toxin (Measles toxin) causing hoarseness is due to lung heat congestion; Xuanshen Shengma Tang (Scrophulariae Radix and Cimicifugae Rhizoma Decoction) has miraculous effects. After the rash subsides, Ercha San (Child's Tea Powder) clears the voice immediately.
Note: Aphonia (loss of voice) is caused by heat-toxin blocking the lung orifices. For aphonia at the initial stage of measles, Xuanshen Shengma Tang is the primary formula; for aphonia after the rash has erupted, Jiajian Liangge San (Modified Cool the Diaphragm Powder) is the primary formula; for hoarseness after the rash has faded, Ercha San is the primary formula.
Xuanshen Shengma Tang (Formula seen previously)
Jiajian Liangge San (Modified Cool the Diaphragm Powder)
Bohe Ye (Menthae Haplocalycis Folium), Sheng Zhizi (Gardeniae Fructus raw), Xuanshen (Scrophulariae Radix), Lianqiao (Forsythiae Fructus, heart removed), Sheng Gancao (Glycyrrhizae Radix et Rhizoma raw), Ku Jiegeng (Platycodonis Radix), Maidong (Ophiopogonis Radix, heart removed), Niubangzi (Arctii Fructus, stir-fried and crushed), Huangqin (Scutellariae Radix).
Decoct in water and take orally.
Rhyme verse: Jiajian Liangge treats aphonia, Bohe, Zhizi, and Xuanshen together; Lianqiao, Gancao, Ku Jiegeng, Maidong, Niubangzi, and Huangqin.
Ercha San (Child's Tea Powder)
Pengsha (Borax, 2 qian), Hai'ercha (Catechu, 5 qian).
Grind into fine powder. Mix one spoonful of medicine with a cup of cool water and take orally.
Why does vomiting and regurgitation occur when the rash erupts? This is because fire-pathogen disturbs the stomach. Zhu Ru and Shigao are the main treatments; harmonizing the middle and clearing heat can calm the vomiting.
Note: Vomiting caused by measles is due to fire-pathogen forcing inward, causing stomach qi to rebel. One must use Zhuru Shigao Tang (Bamboo Shavings and Gypsum Decoction) to harmonize the middle and clear heat, and the vomiting will stop naturally.
Zhuru Shigao Tang (Bamboo Shavings and Gypsum Decoction)
Banxia (Pinelliae Rhizoma, prepared with ginger juice), Chiling (Poria Cocos with red skin), Chenpi (Citri Reticulatae Pericarpium), Zhuru (Bambusae Caulis in Taeniam), Sheng Gancao (Glycyrrhizae Radix et Rhizoma raw), Shigao (Gypsi Fibrosus).
Decoct with fresh ginger as a guiding herb and take orally.
Rhyme verse: Zhuru Shigao Tang treats vomiting, Banxia prepared with ginger paired with Fuling; Chenpi, Zhuru, Sheng Gancao, and Shigao clearing fire combine to form it.
Toxic-heat transfers into the Large Intestine meridian, disrupting transmission and transformation, leading to diarrhea. At the initial stage, Shengge Tang (Shengma Ge Gen Tang) with modifications is used; after the rash has appeared and diarrhea persists, Huanglian Jiedu Tang (Coptis Decoction for Resolving Toxicity) clears the heat-toxin.
Note: Diarrhea caused by measles results from toxic-heat transferring into the intestines and stomach, disrupting transmission and transformation. The practitioner must absolutely avoid using warm-tonifying formulas. For diarrhea at the initial stage of the rash, Shengma Ge Gen Tang (Cimicifugae and Puerariae Decoction) added with Chiling, Zhuling (Polyporus), and Zexie (Alismatis Rhizoma) is used; for diarrhea after the rash has erupted, Huanglian Jiedu Tang added with Chiling and Mutong (Akebiae Caulis) is used.
