In the formula of Zhizi Chi Tang (Gardenia and Fermented Soybean Decoction), add Gancao (Licorice Root, *Glycyrrhizae Radix et Rhizoma*) two liang. Follow the previous method for preparation and administration. If vomiting occurs, discontinue the remaining dose.
When the syndrome of Zhizi Chi Tang is present, if there is a sensation of shortness of breath (Shaoqi, Qi deficiency manifesting as weak respiration), add Gancao (Licorice Root) to this base formula. Note: Shortness of breath results from the depletion of body fluids (Jinye). Adding Gancao utilizes its ability to tonify the Middle Jiao and preserve fluids, as well as its capacity to carry the medicinal action upward to induce rapid emesis.
In the formula of Zhizi Chi Tang (Gardenia and Fermented Soybean Decoction), add Shengjiang (Fresh Ginger, *Zingiberis Rhizoma Recens*) five liang. Follow the previous method for preparation and administration. If vomiting occurs, discontinue the remaining dose.
When the syndrome of Zhizi Chi Tang is present, if vomiting is present, add Shengjiang (Fresh Ginger) to this base formula. Vomiting indicates that the heat in the upper diaphragm has invaded the Stomach. Shengjiang possesses ascending and dispersing properties; it guides the heat in the Stomach to be vomited out entirely. Thus, it serves as an emetic guide.
Zhizi (Gardeniae Fructus, *Gardeniae Fructus*) fourteen seeds, broken apart; Ganjiang (Dried Ginger, *Zingiberis Rhizoma*) two liang.
These two ingredients are boiled in three and a half sheng of water to obtain one and a half sheng of decoction. Strain the dregs. Divide into three doses. Take one dose warm. If vomiting occurs after taking a dose, discontinue the remaining doses.
In Cold Damage (Shanghan), if a physician used pill-based purgatives to cause severe downward purging, resulting in persistent body heat and slight restlessness (Wei Fan), Zhizi Ganjiang Tang (Gardenia and Dried Ginger Decoction) should be administered. Yu Jiayan argued that this is a method of warming the middle and dissipating pathogens. I disagree. Warming the middle is not suitable with Zhizi, and since the middle jiao requires warming, how can one tolerate further emesis? Generally, erroneous purgation leads to the internal entrapment of Yang pathogens. In this case, although erroneous purgation occurred, the persistence of body heat and slight restlessness indicate that the Yang pathogen has not yet fully entered the interior. Therefore, it can be guided upward to exit. Ganjiang must be used to block the path of the Yang pathogen entering the interior, allowing Zhizi to carry the pathogen upward. One cold and one warm, seemingly opposite but actually complementary, constitutes the sagely method.
Zhizi (Gardeniae Fructus) fourteen seeds, broken apart; Houpo (Magnolia Bark, *Magnoliae Officinalis Cortex*) four liang, processed with ginger juice; Zhishi (Immature Bitter Orange, *Aurantii Fructus Immaturus*) four liang, soaked in water, pith removed, stir-fried.
These three ingredients are boiled in three and a half sheng of water to obtain one and a half sheng of decoction. Strain the dregs. Divide into three doses. Take one dose warm. If vomiting occurs after taking a dose, discontinue the remaining doses.
Although this formula aims at inducing emesis, it does not rely exclusively on the emetic method. After erroneous purgation in Cold Damage, if there is mental irritability (Xin Fan), abdominal fullness, and restlessness in lying down or sitting up, Zhizi Houpo Tang (Gardenia and Magnolia Bark Decoction) should be administered. Although the exterior pathogen was subjected to erroneous purgation, mental irritability indicates the pathogen partially occupies the Upper Jiao, while abdominal fullness indicates the pathogen partially sinks into the Lower Jiao. Therefore, Zhizi is used to涌 (surge/induce expulsion of) the pathogen in the Upper Jiao, while Zhishi and Houpo are used to unblock the Qi in the Lower Jiao. This is also a method of resolving both upper and lower aspects simultaneously.
