Add two qian bi (a traditional unit of measurement for powder) to each dose, adjusting the dosage flexibly according to the patient's condition.
Question: If a patient is affected by external pathogens such as frost, dew, mountain mist, and rain dampness, with no significant pain in the head, neck, or body, but only heaviness and fatigue in the four limbs, decreased appetite, or chest and epigastric fullness after eating, and the Cun pulse (radial artery at the wrist position closest to the thumb) is hidden and small, which resembles internal injury from drinking cold substances, what is the cause?
Answer: This condition is common in people who rarely consume rich and sweet foods and have a constitutionally weak qi. This is because yin-cold qi has already latent within the body. If one travels early in the morning on an empty stomach, or speaks excessively, causing the qi expelled through the mouth and nose to dissipate, the yin qi becomes relatively stronger, leading to disease. The *Classic of Difficult Issues* states: "Pathogenic qi from heaven, when contracted, harms the five zang organs." Even without drinking cold water, the Cun pulse will be small. It also states: "Those injured by dampness are first affected from below." Therefore, one should seek the similar pathogenesis from internal contraction of pathogens. Zhang Zhongjing said: "Turbid qi attacks the lower jiao," referring to this situation.
The *Classic of Difficult Issues* states: "Clear pathogens attack the upper jiao; turbid pathogens attack the lower jiao." Fog and dew belong to the same category of pathogens. Thus, the Cun pulse is small; similarly, in cases of internal injury from drinking cold, the Cun pulse is also small. When fog and dew enter the abdomen, although no cold water is drunk, the damage is equivalent to that of drinking cold; conversely, internal injury from drinking cold, although not caused by fog and dew, is equivalent to the damage caused by them. Why? Because in both cases, the pulse is yin-type, and the Cun pulse is small. Here, quoting Qibo again to judge, it is concluded that turbid qi attacking the lower jiao causes damage similar to that of drinking cold. Han Zhihe stated that if the Cun pulse is faint and small, purgative methods should not be used; from this, it can be known that yin is excessive and yang qi cannot ascend to the highest heaven.
Treatment for conditions involving internal injury from cold substances and external contraction of wind pathogens, presenting with sweating.
Baizhu (Atractylodis Macrocephalae Rhizoma, 2 liang)
Fangfeng (Saposhnikoviae Radix, 2 liang)
Gancao (Glycyrrhizae Radix et Rhizoma, roasted, 1 liang)
Crush the above herbs. For each dose, weigh 3 qian. Add one lamp of water and three slices of fresh ginger. Decoct together until reduced to seven-tenths. Strain and take warm. Take one sip regardless of time. Usually, one or two doses are sufficient. Wait for two to three days until sweating gradually decreases, indicating recovery.
The Fangfeng Baizhu Muli Tang (Windproof Atractylodes and Oyster Shell Decoction) from *Huo Ren* (likely referring to *Shanghan Baiwen Ge*) should be listed below this formula.
In Wind-Warmth syndrome, symptoms include red face, spontaneous sweating, silence with unwillingness to speak, desire to sleep, and floating-slow or faint pulses in both hands. This syndrome is unsuitable for diaphoresis (sweating therapy). If diaphoresis is incorrectly applied, it may lead to muscle twitching (jin ti rou tian), delirious speech, restlessness, and inability to lie down. If purgation is incorrectly applied, it may lead to fixed staring and incontinence of urine and feces. If fire therapy is incorrectly applied, it may lead to mania resembling convulsive epilepsy. One misstep may prolong the illness, but a second misstep will hasten death. The Benfang Weirui Tang (Reed Rhizome Decoction) from *Huo Ren* contains Mahuang (Ephedrae Herba), so it dare not be used. Instead, the aforementioned Baizhu Tang should be used as the primary treatment.
For dizziness, sweating, and muscle twitching, add Muli (Ostreae Concha).
For stiffness and rigidity of the waist and back, add Qianghuo (Notopterygii Rhizoma et Radix).
For dry tongue and thirst, add Renshen (Ginseng Radix).
For severe burning heat of the body, add Zhimu (Anemarrhenae Rhizoma). Do not add if caused by internal injury from cold.
For heavy body and profuse sweating, add Huangqi (Astragali Radix).
