Jiegeng (Platycodonis Radix), Beimu (Fritillariae Bulbus) (each 3 fen; in ancient methods, 2 qian 5 fen equals 1 fen), Badou (Crotonis Fructus) (1 fen, peeled, heart removed, stir-fried until black, ground into a paste). The above three ingredients are made into a powder. Add Badou and continue to pound in a mortar. Take with rice water (Bai Yin). For strong individuals, take half a Qianbi dose (approximately 3 fen by modern weighing); for frail individuals, reduce the dose. If the disease is located above the diaphragm, vomiting will inevitably occur; if below the diaphragm, diarrhea will inevitably occur. If there is no diarrhea after taking the medicine, drink one bowl of hot porridge to promote the effect; if diarrhea persists excessively, drink one bowl of cold porridge to stop it. Badou acts when heated and stops when cooled. If body heat and skin pruritus (pi su) do not resolve, accompanied by aversion to cold and shivering (han su), with a desire to cover oneself with clothes, using water to wash or pour over the body will only further trap the heat, preventing its release. Sweat should occur but does not, leading to irritability (fan). If sweating occurs after administration but abdominal pain follows, administer Shaoyao (Paeoniae Radix Alba) 3 liang according to the aforementioned method.

The so-called Cold-Shi Jie Xiong (Cold-Excess Chest Binding): generally, Jie Xiong syndromes are caused by heat sinking inward. Here, "Cold-Shi" refers to phlegm-fluid retention condensed by cold qi and coldness. In the absence of heat signs, Sanwu Xiaoxin Tang (Three-Ingredient Minor Bitter Pill Decoction) can be given; Baisan (White Powder) is also applicable. Note: *Huoren Shu* states: "Administer Sanwu Baisan," omitting the seven characters "Xiaoxin Tang may also be used." This is likely because Xiaoxin Tang is a cold-natured formula, unsuitable for conditions without heat.

(Maren Wan) consists of Xiao Chengqi Tang plus Shaoyao and two types of seeds.
Maziren (Semen Cannabis) (2 sheng), Shaoyao (Paeoniae Radix), Zhishi (Aurantii Fructus Immaturus) (each 0.5 jin, prepared by stir-frying), Dahuang (Rhei Radix et Rhizoma) (1 jin, peeled), Houpo (Magnoliae Officinalis Cortex) (1 chi, prepared by stir-frying and peeled), Xingren (Semen Armeniacae Amarum) (1 sheng, peeled, tips removed, stir-fried and separately ground into a paste). The above six ingredients are powdered. Mix with refined honey to form pills the size of wutong seeds. Take ten pills with water, three times daily. Gradually increase the dose until therapeutic effect is achieved.

The Fuyang pulse is floating and choppy (se). A floating pulse indicates strong stomach qi and excess yang; a choppy pulse indicates frequent urination and insufficient yin. The interaction of floating and choppy pulses leads to hard stools, known as Pi Yue (Spleen Constriction). This corresponds to the statement in the treatise: "Taiyang transmitting to Yangming constitutes Pi Yue." Maren Wan is the primary formula. Since Taiyang transmits directly to Yangming without further transmission, gentle treatment methods can be employed.

Shengjiang (Zingiberis Rhizoma Recens) (4 liang, sliced), Gancao (Glycyrrhizae Radix et Rhizoma, prepared by stir-frying), Renshen (Ginseng Radix), Huangqin (Scutellariae Radix) (each 3 liang), Banxia (Pinelliae Rhizoma) (0.5 sheng, washed), Huanglian (Coptidis Rhizoma), Ganjiang (Zingiberis Rhizoma) (each 1 liang), Dazao (Jujubae Fructus) (12 pieces, torn open). The above eight ingredients are boiled in 1 dou of water to obtain 6 sheng of liquid. Remove dregs, decoct again to obtain 3 sheng. Take 1 sheng warm, three times daily.

After treating Shanghan (Cold Damage) with sweating therapy, once the exterior syndrome resolves but the stomach interior remains disordered, presenting with epigastric fullness and hardness, belching with food odor, fluid retention under the costal region, borborygmus, and diarrhea, Shengjiang Xiexin Tang (Ginger Heart-Draining Decoction) is indicated. After sweating, if pathogens remain incomplete, lingering fluids must reside in the epigastrium. The symptoms are complex; however, each herb in the formula targets specific symptoms. Some herbs treat two symptoms, while combinations of two herbs treat one symptom. There is intricate variation, combining purgation and tonification, and using cold and hot properties together. These methods are based on the prescription principles of *Neijing* (Inner Canon), and the properties of the herbs align perfectly with those recorded in *Shennong Bencao Jing* (Divine Farmer's Materia Medica). Practitioners who study the principles behind such formulas and apply them flexibly will master therapeutic control.
All methods involving Xiexin (Heart-Draining) formulas address residual ailments following prior sweating, purging, or emesis.
