In Taiyang Wind-stroke syndrome with diarrhea and vomiting/retching, once the exterior syndrome is resolved, one may proceed to attack the interior. If the patient sweats, with headaches occurring at specific times, epigastric fullness and hardness radiating to the hypochondrium, dry retching, shortness of breath, sweating without aversion to cold, this indicates that the exterior pathogen has resolved but the interior qi is not harmonized. Shizao Tang (Ten Jujube Decoction) is the primary formula.

Taiyang Wind-stroke with diarrhea and vomiting/retching indicates the presence of internal water-dampness. According to the methods, it can be attacked, but only after the exterior pathogen has completely resolved externally. If there is internal water-qi repelling Yang Qi to the exterior, causing steaming pores and sweating, with alternating dominance of Yin and Yang resulting in periodic episodes; if water-drink obstruction prevents turbid Qi from descending, causing headache; if Yin pathogen fills upward, causing epigastric stuffiness, hardness, and pain radiating to the hypochondrium; if Stomach Qi rebels upward causing dry retching; if Lung Qi rebels upward causing distressing shortness of breath—unless obstructed by water-drink stagnation, how could it reach such a state? If the patient sweats and no longer has aversion to cold, it means the exterior pathogen has resolved, but the interior Qi is unharmonized. Shizao Tang (Ten Jujube Decoction) should be used. Dazao (Jujube) protects Spleen essence, while Yuanhua (Genkwa Flower), Gansui (Kansui Root), and Daji (Euphorbia Lathyris Root) drain the water-drink.

Dazao (ten pieces) Yuanhua Gansui Daji

The above three herbs are mixed in equal parts, each pounded and sifted into powder. Take one and a half sheng of water, first decoct ten large Dazao until reduced to eight ge, remove the dregs, and add the herb powders. Strong individuals take one cun-bi (a measure roughly equivalent to a teaspoonful); frail individuals take half a cun-bi. Take warm on an empty stomach in the morning. If the purgation is slight and the disease persists, administer again the next day, increasing by half a cun-bi. After achieving rapid purgation (profuse watery stool), nourish oneself with millet porridge.

After Taiyang disease is resolved via sweating, if the Stomach is disharmonious, presenting with epigastric stuffiness and hardness, frequent belching with a smell of food rot, water-qi accumulating under the hypochondrium, borborygmus in the abdomen, and diarrhea, Shengjiang Xiexin Tang (Fresh Ginger Decoction for Harmonizing the Heart) is the primary formula.

After Taiyang disease is resolved via sweating, if the Stomach is disharmonious, presenting with epigastric stuffiness and hardness, inability to digest water and grain, retention of old food residues, turbid Qi rushing to the chest causing dry retching and food-rotting belch; if Gallbladder pathogen overacts on Earth (Spleen), causing Spleen deficiency unable to control water, leading to water stagnation in the Gallbladder region and accumulation under the hypochondrium; if Earth fails and Wood (Liver) invades, causing agitation of Yin Qi, borborygmus in the abdomen, and diarrhea: In Shengjiang Xiexin Tang, Shengjiang (Fresh Ginger) and Banxia (Pinellia Tuber) descend turbid Yin; Huangqin (Scutellaria Root) and Huanglian (Coptis Rhizome) clear Heat from the Heart and Gallbladder; Ganjiang (Dried Ginger), Gancao (Licorice Root), Renshen (Ginseng Root), and Dazao (Jujube) warm and tonify Middle Qi to rotate the pivot mechanism.
