有初病而自汗出，其后热甚而反不得汗出者，此阳气发泄，而阴气不足故也。（张东扶
曰∶阳气发泄，故初病即有汗；阴血不足，故热盛反无汗。）宜用芎归汤一、二帖后，再加苏梗
一、二分，则汗出而愈矣。
又有寒热交作，汗出热退，少顷又寒，此阴阳不和，宜小柴胡汤加川芎、当归、白芍。
盖余邪未尽，则阴阳不和。用人参、甘草、半夏以和阳；川芎、当归、白芍以和阴；柴胡、茯苓
以彻半表半里之热也。

洪大而无力之脉，用六味而不加人参，火退脉必涩；盖加人参，则气下也。此皆求下之道也
中湿证，表现为全身僵硬强直，四肢大多倦怠无力无法抬起，治疗法则应当疏通并利导小便，切不可轻易使用泻下法。
在雨中或露天环境，穿着湿衣、身处湿地，都能导致受湿而发病，病位主要在肝经和脾经，症状包括大便泄泻、小便色赤、脉象微细且缓。
有的患者初起时自发出汗，随后高热反而无汗，这是因为阳气外越发泄，而阴气（阴血）不足所致。（张东扶说：阳气外越发泄，所以初病就有汗；阴血不足，所以热盛时反而无汗。）适宜服用芎归汤一至两帖后，再加苏梗一、二分，即可出汗而痊愈。
又有寒热交替发作，出汗后热退，片刻后又发冷，这是阴阳不和，适宜用小柴胡汤加川芎、当归、白芍。
因为余邪未尽，导致阴阳不和。用人参、甘草、半夏来调和阳气；用川芎、当归、白芍来调和阴血；用柴胡、茯苓来清除半表半里的热邪。
有的患者六脉空大且迟缓，里气已经虚弱，身体轻微恶寒，而表邪尚未清除，可用白术一钱、附子三分，加桑叶……（原文此处似有缺漏，结合下文推测为加桑叶等药）。
又有夏秋之交，身体发热、恶寒且脉象豁大，适宜用芎归汤加桑叶。
或者是寒气，或者是寒饮，食物停滞在胸膈之间，用理中汤调和它，托住正气，自然会引起呕吐。
膈上有痰，感到满闷壅滞，适宜催吐，用炒盐调沸开水探吐。
绞肠痧，用盐调沸开水探吐。
夹带食积和停痰，肢体弯曲不能伸直，用平胃散、二陈汤消导，自然呕吐。
痰涎壅塞，用胆矾三分、硼砂二分，研成粉末，用沸水调服以催吐。
久病虚损，用补中益气汤加苏梗、杏仁，或者芎归汤加二陈汤，或者六味地黄丸来滋润并引导下行。
杂病一个月，饮食摄入减少，烦热不退，适宜用补中益气汤加苏梗、杏仁；若腹胀，加生姜、肉桂、吴茱萸少许。
阴道的道理。（张东扶说：五味子只有肾虚津液少导致口渴时才适宜使用，其余情况应当审慎使用。）
凡是久病，左脉沉虚，右脉洪大，大便干结燥硬，这是阳气下陷于阴分，脾胃受病的表现。用六味地黄丸加人参、车前子。又如有久病患者左脉沉虚，右脉洪大，起初是正气虚弱下陷，适宜用补中益气汤升提。如果下陷时间已久，阴血干涸，气血俱虚，燥火更加炽盛，如果此时升提则会导致头痛、喉痛等症状发作，必须适宜用地黄丸壮水之主以制约阳光（亢盛的阳火）。
脉象洪大但无力的，用六味地黄丸而不加人参，火热退去后脉象必然涩滞；因为加了人参，气机就会下降。这些都属于“求下”的治疗途径。
Zhongshi (Intermediate Dampness) presents with whole-body stiffness and rigidity, and the limbs are mostly fatigued and unable to move. The treatment principle should be to unblock and promote urination; one must not lightly use purgative methods.
Exposure to rain or open air, wearing wet clothes, or lying on damp ground can all lead to disease caused by dampness. The pathology involves the Liver and Spleen meridians, with symptoms including loose stools, dark urine, and a pulse that is faint and slow.
In some cases, spontaneous sweating occurs at the onset of the disease, followed by high fever but an inability to sweat. This is due to the dispersion of Yang Qi and insufficient Yin Qi. (Zhang Dongfu stated: Because Yang Qi disperses, there is sweating at the onset; because Yin Blood is insufficient, there is no sweating despite intense heat.) It is appropriate to administer Xiong Gui Tang (Sichuan Lovage and Angelica Decoction) for one to two doses, then add 1-2 fen of Perillae Caulis (Sugeng). Sweating will occur, and the patient will recover.
In other cases, alternating chills and fever occur; after sweating, the fever subsides, but chills return shortly thereafter. This indicates disharmony between Yin and Yang. It is appropriate to use Xiao Chai Hu Tang (Minor Bupleurum Decoction) added with Chuanxiong Rhizome (Chuanxiong), Angelicae Sinensis Radix (Danggui), and Paeoniae Radix Alba (Baishao).
Since residual pathogens remain, Yin and Yang are in disharmony. Ginseng Radix et Rhizoma (Renshen), Glycyrrhizae Radix et Rhizoma (Gancao), and Pinelliae Tuber (Banxia) are used to harmonize Yang; Chuanxiong Rhizome (Chuanxiong), Angelicae Sinensis Radix (Danggui), and Paeoniae Radix Alba (Baishao) are used to harmonize Yin; Bupleuri Radix (Chaihu) and Poria (Fuling) are used to clear heat from the half-exterior and half-interior.
In some cases, the six pulses are empty, large, slow, and sluggish. The interior Qi is already deficient, the body feels slightly aversion to cold, and exterior pathogens have not yet been cleared. One may use Atractylodis Macrocephalae Rhizoma (Baizhu) 1 qian, Aconiti Lateralis Radix Praeparata (Fuzi) 3 fen, plus... [text incomplete].
During the transition between summer and autumn, if the body is hot, aversed to cold, and the pulse is large and hollow, it is appropriate to use Xiong Gui Tang (Sichuan Lovage and Angelica Decoction) added with Morus Folium (Sangye).
If it is cold Qi or cold fluid retention, with food stagnating in the chest and diaphragm, Li Zhong Tang (Regulate the Middle Decoction) is used to harmonize it, supporting the healthy Qi so that vomiting occurs naturally.
If food is in the stomach, Ping Wei San (Calm the Stomach Powder) and Er Chen Tang (Two-Cured Decoction) are used to raise Stomach Qi, allowing vomiting to occur naturally.
If phlegm is above the diaphragm, causing fullness, oppression, and stagnation, emesis is indicated. Boiled water mixed with roasted salt is used to induce vomiting.
For Jiaochangsha (Intestinal Twisting Sha), boiled water mixed with salt is used to induce vomiting via probing the throat.
When food stagnation and retained phlegm are present, causing the limbs to curl and not straighten, Ping Wei San (Calm the Stomach Powder) and Er Chen Tang (Two-Cured Decoction) are used for digestion and resolution, leading to natural vomiting.
If saliva and phlegm are obstructing, Danfan (Alumen) 3 fen and Pengsha (Borax) 2 fen are ground into powder and taken with boiling water to induce vomiting.
For chronic deficiency and damage, Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction) added with Perillae Caulis (Sugeng) and Armeniacae Semen Amarum (Xingren), or Xiong Gui Tang (Sichuan Lovage and Angelica Decoction) added with Er Chen Tang (Two-Cured Decoction), or Liu Wei Di Huang Wan (Six-Ingredient Rehmannia Pill) to moisten and guide downward, may be used.
In miscellaneous diseases lasting one month, with reduced dietary intake and persistent irritability and heat, Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction) added with Perillae Caulis (Sugeng) and Armeniacae Semen Amarum (Xingren) is appropriate. If abdominal distension is present, add small amounts of Zingiberis Rhizoma Recens (Shengjiang), Cinnamomi Cortex (Guirou), and Evodiae Fructus (Wuzhuyu).
This relates to the Way of Yin. (Zhang Dongfu stated: Schisandrae Fructus (Wuweizi) is only suitable for thirst caused by Kidney deficiency and scanty fluids; in other cases, it should be used with caution.)
In any chronic disease, if the left pulse is deep and deficient, the right pulse is large and surging, and the stool is dry and hard, this indicates Yang sinking into the Yin aspect, with disease affecting the Spleen and Stomach. Liu Wei Di Huang Wan (Six-Ingredient Rehmannia Pill) added with Ginseng Radix et Rhizoma (Renshen) and Plantaginis Semen (Cheqianzi) is indicated. In another case of chronic disease where the left pulse is deep and deficient and the right pulse is large and surging, initially, when healthy Qi is deficient and sinking, Bu Zhong Yi Tang (Tonify the Middle Decoction) should be used to raise it. However, if the sinking has persisted for a long time, Yin Blood is dried up, Qi and Blood are both deficient, and dry fire is increasingly fierce, using raising methods would trigger symptoms such as headache and sore throat. In such cases, it is necessary to use Dihuang Wan (Rehmannia Pill) to strengthen the source of Water to control the excessive Yang (Sunlight).
For a pulse that is large and surging but forceless, Liu Wei Di Huang Wan (Six-Ingredient Rehmannia Pill) should be used without adding Ginseng Radix et Rhizoma (Renshen); otherwise, after the fire subsides, the pulse will become choppy. This is because adding Ginseng causes Qi to descend. These are all methods of "seeking descent."
