When dry heaving occurs in smallpox, the disease condition is severe; toxic heat rebels upward, making it difficult for the healthy qi to withstand. For excess-heat patterns, Chupi Zhuru Tang (Tangerine Peel and Bamboo Shavings Decoction) is indicated; for deficiency-cold patterns, Dingxiang Shidi Tang (Clove and Persimmon Calyx Decoction) is miraculous.
[Note] Dry heaving refers to a sound without vomitus, characterized by a loud and prolonged noise, belonging to the Yangming Stomach Meridian. It is caused by the rebellion of toxic heat upward. Additionally, there are cases where insufficient stomach qi fails to receive and contain, compounded by cold pathogens lodging in the stomach, preventing stomach qi from governing the middle jiao, causing it to rebel upward and induce heaving. For heat patterns, Chupi Zhuru Tang is the primary formula; for cold patterns, Dingxiang Shidi Tang is the primary formula.
Chupi Zhuru Tang (Tangerine Peel and Bamboo Shavings Decoction)
Citri Reticulatae Pericarpium Rubrum (Juhong), Pinelliae Rhizoma Preparatum cum Zingibere (Banxia, processed with ginger), Ophiopogonis Radix (Maidong, heart removed), Eriobotryae Folium (Pipaye, roasted with ginger), Glycyrrhizae Radix et Rhizoma (Gancao, raw), Bambusae Medulla (Zhuru), Poria (Chiling), Ginseng Radix et Rhizoma (Renshen).
Reference: Phragmitis Rhizoma (Lugen), decocted in water and taken orally.
[Fang Ge - Formula Song] Chupi Zhuru Tang is effective as if divine, specifically treating frequent vomiting due to stomach heat; it contains Tangerine Peel, Pinellia, Ophiopogon, Loquat Leaf, Licorice, Bamboo Shavings, Poria, and Ginseng.
Dingxiang Shidi Tang (Clove and Persimmon Calyx Decoction)
Eugeniae Flos (Dingxiang), Ginseng Radix et Rhizoma (Renshen), Alpiniae Officinarum Rhizoma (Gaoliangjiang), Diospyros Fructus Calyx (Shidi).
Decocted in water and taken orally.
[Fang Ge - Formula Song] Dingxiang Shidi Tang treats cold patterns, calming rebellious stomach qi that causes unrest; Clove, Galangal, and Ginseng are combined, along with Persimmon Calyx, decocted together.
For vomiting caused by abundant toxins, Erchen Tang (Two-Aged Decoction) is beneficial; for vomiting accompanied by difficulty in swallowing, Niuzangzi Tang (Arctii Seed Decoction) is used; for vomiting of sour regurgitation due to food stagnation, Muxiang Da'an Wan (Aucklandia Great Peace Pill) is effective; for vomiting due to qi deficiency, Hewei Fang (Stomach-Harmonizing Formula) is employed.
[Note] Vomiting (Ou) involves both sound and matter; spitting up (Tu) involves matter but no sound. Both syndromes belong to the Stomach. When vomiting occurs at the initial eruption stage of smallpox, it is due to fire pathogens invading the stomach and toxic vapors surging upward; the pustules will necessarily appear red or purple, and Zhilian Erchen Tang (Gardenia and Coptis Two-Aged Decoction) should be used. When vomiting occurs from the swelling phase to the crusting phase, it is caused by toxin accumulation at the pharynx leading to dysphagia; Niuzangzi Tang must be used. If vomiting is due to food stagnation, the vomitus will have a fishy and sour odor; Muxiang Da'an Wan should be used. If after vomiting the spirit is fatigued and there is no desire for food, this indicates stomach qi deficiency; Shensha Hewei Tang (Ginseng and Amomum Stomach-Harmonizing Decoction) is the primary treatment.
Zhilian Erchen Tang (Gardenia and Coptis Two-Aged Decoction)
Citri Reticulatae Pericarpium (Chenpi), Pinelliae Rhizoma Preparatum cum Zingibere (Banxia, processed with ginger), Poria (Fuling), Glycyrrhizae Radix et Rhizoma (Gancao, raw), Gardeniae Fructus (Zhizi, stir-fried with ginger), Coptidis Rhizoma (Chuanlianhong, stir-fried with ginger).
Reference: Zingiberis Rhizoma Recens (Shengjiang), decocted in water and taken orally.
[Fang Ge - Formula Song] Toxic vapors rushing into the stomach cause frequent vomiting; treatment requires using Erchen Tang as a base, comprising Chenpi, Banxia, Fuling, Gancao, and Gardenia and Coptis stir-fried with ginger, proving as effective as divine intervention.
Jiawei Niuzangzi Tang (Modified Arctii Seed Decoction)
Platycodonis Radix (Jiegeng), Belamcandae Rhizoma (Shegan), Forsythiae Fructus (Lianqiao, heart removed), Schizonepetae Spica (Jingjie), Saposhnikoviae Radix (Fangfeng), Sophorae Tonkinensis Radix (Shandougen), Arctii Fructus (Niuzangzi, fried and ground), Puerariae Radix (Gange).
