琥按成注云。茯苓甘草之甘。益津液而和卫。桂枝生姜之辛。助阳气而解表。彼以姜桂味辛走表。能助阳气。注甚
明切。若茯苓味甘而淡。乃泄水之物。何以能益津液。盖膀胱之邪水利。则气化得以流通。津液即由此而回复。所以五
苓散。散邪消水。为最燥之药。成注反云润燥者。亦此义也。至其云。和卫。乃甘草之力。与茯苓何与焉。成氏以上病。
止汗出而不渴。为邪气不传里。但在表而表虚。故以上汤为解表和卫之剂。从不云茯苓之主里。此为论与方两失其义。
琥又按五苓散。茯苓甘草汤。二方皆太阳标本齐病。表里兼主之剂。何谓标太阳之经是也。何谓本。膀胱府是也。
经在表。本在里。五苓散证。邪已入府。表证实微。故方中止用桂枝一味以主表。其余四味。皆主里之药也。茯苓甘草
汤证。邪犹在经。里证尚少。故方中止用茯苓一味。以主里。其余三味。皆主表之药也。学人能于仲景书反复玩索。其

Poria (Liang Er), Cinnamon Twig (Liang Er, peeled), Fresh Ginger (San Liang, sliced), Licorice Root (Liang Yi, honey-fried)
The above four ingredients. Boil in four sheng of water. Reduce to three sheng. Remove the dregs. Divide into three warm doses.
Hu notes: Cheng Wuji's commentary states: "The sweetness of Poria and Licorice tonifies body fluids and harmonizes Wei Qi; the pungency of Cinnamon Twig and Fresh Ginger assists Yang Qi and releases the exterior." The annotation that ginger and cinnamon, being pungent and traveling to the exterior, can assist Yang Qi is very clear and pertinent. As for Poria, which is sweet and bland, it is a substance that drains dampness; how can it tonify body fluids? This is because when the water-damp pathogen in the Bladder is excreted, Qi transformation flows freely, and body fluids are thereby restored. Therefore, Wuling San (Five-Ingredient Powder with Poria), despite being a drying medicine for dispelling pathogens and eliminating water, was described by Cheng as moistening dryness; this is also based on this principle. Regarding his statement "harmonizing Wei," that is the power of Licorice, what does it have to do with Poria? Cheng, observing symptoms of sweating without thirst, concluded that the pathogen had not transmitted to the interior but remained at the exterior with deficiency. Thus, he regarded the above formula (Fuling Gancao Tang) as a formula to release the exterior and harmonize Wei, never mentioning that Poria treats the interior. This is a loss of meaning in both the text and the formula.
Hu further notes: Both Wuling San and Fuling Gancao Tang are formulas treating simultaneous disease of the Biao (Exterior/Channel) and Ben (Interior/Organ) of Taiyang. What is Biao? It is the Taiyang Channel. What is Ben? It is the Bladder Fu organ. The Channel is at the exterior, the Fu is at the interior. In Wuling San syndrome, the pathogen has entered the Fu, and the exterior excess is slight; thus, only one ingredient, Cinnamon Twig, is used to treat the exterior, while the other four ingredients all treat the interior. In Fuling Gancao Tang syndrome, the pathogen remains in the Channel, and interior symptoms are few; thus, only one ingredient, Poria, is used to treat the interior, while the other three ingredients all treat the exterior. If students repeatedly study Zhang Zhongjing's works, their profound meanings will naturally become apparent.
(Repeated Case: Wind-stroke with fever for six or seven days unresolved... named Water Reversal, treated with Wuling San. (Seen previously))
Before taking the pulse, the patient crosses hands over the heart. The physician then instructs them to try to cough. If they do not cough, this must be bilateral deafness. Why is this so? Because excessive sweating has caused deficiency. (This is Zhang Zhongjing demonstrating diagnostic methods. Physicians must take the pulse first. Here, before taking the pulse, the physician intends to palpate the wrist, but the patient crosses hands over the heart. At this time, the patient's spirit is not engaged with the physician. The physician uses a test method. 'Hand crossing' means hands interlaced. The annotation is seen previously. Being instructed to cough but not doing so indicates deafness. The reason is that excessive sweating causes Yang collapse, leading to depletion of Zong Qi in the chest, unable to fill, hence hands cross over the heart. Repeated sweating makes Jing-Qi more deficient, unable to ascend to the ears, hence deafness. *Shanglun Pian* states: This deafness is distinctly different from deafness due to excess pathogen in Shaoyang transmission. Cheng Wuji comments: Yang Qi is deficient, Jing-Qi is insufficient. Actually, Yang Qi and Jing-Qi are not two separate entities. Yang Qi in the body is Qi; accumulated Qi becomes Jing. Qi is the mother of Jing, Jing is the child of Qi. Qi is governed by the Lung, and the chest-heart is its domain. Jing is governed by the Kidney, and the two ears are its orifices. Also, regarding this condition, Zhang Zhongjing provides no treatment method. *Buwang Lun* by Chang Qizhi says: For those without prior heat, Shaoyao Fuzi Tang may be used. For those with prior heat, Huangqi Jianzhong Tang may be used. I believe that since deficiency results from excessive sweating, Huangqi Jianzhong Tang is indeed appropriate. However, Jing-Qi deficiency is not Fire deficiency; Shaoyao Fuzi Tang is inappropriate. As for whether the patient had prior heat, this is the most laughable diagnostic method of Chang.)
After sweating, drinking too much water inevitably causes wheezing. Washing the body with water also causes wheezing. (Wheezing is a lung disease. The classic states: Cold affecting the form and cold drinks injure the lungs. After sweating, body fluids are lost causing dryness and thirst. Drinking excessive water internally leads to rebellious Qi of water, inevitably causing wheezing. Externally washing with water allows cold air to invade the skin, combusting with internal pathogens, also causing wheezing. Regarding this clause, Zhang Zhongjing provides no treatment. *Buwang Lun* by Chang Qizhi says: Mahuang Xingzi Gancao Shigao Tang may be used. I believe that after sweating, washing with water closes the sweat pores with cold-water, making the above formula appropriate. However, it is better to still use Mahuang Tang to induce sweating. If after sweating, excessive water is drunk and sweat pores are likely loose, the above formula is not suitable. Instead, Fuling Guizhi Shengjiang Gancao Tang should be used. For severe wheezing, add Houpo and Xingren.)
After sweating, if water and medicine cannot enter the mouth, it is a reversal pattern. If sweating is induced again, vomiting and diarrhea will certainly not cease. (After sweating, inability to take food and water indicates excessive use of Mahuang Tang to sweat, leading to Yang collapse from profuse sweating. Yuan Qi in the Stomach is deficient and cannot transform water. This is therapeutic reversal, meaning improper treatment. The physician, unaware of the medication error, administers the previous formula again to sweat, causing severe deficiency of Yuan Qi in the Stomach. The ingested medicine is not only vomited but also causes incessant diarrhea. This is great reversal. This is why Zhang Zhongjing deeply emphasizes caution. Regarding this clause, Zhang Zhongjing provides no rescue method. *Buwang Lun* by Chang Qizhi says: Banxia Fuling Tang may be used.)
After sweating, vomiting, or purging, deficiency vexation occurs, preventing sleep. If severe, the patient tosses and turns, feeling stifled in the heart, treated with Zhizi Chi Tang. (After sweating, vomiting, or purging refers to cases where, despite these treatments, the pathogenic heat of Shanghan remains unresolved. Unresolved pathogenic heat takes advantage of deficiency to lodge in the chest. Heat stagnating in the chest generates vexation, disturbing Yang Qi and preventing sleep. 'Severe' means extreme vexation. Extreme vexation indicates more severe stagnated heat in the chest, causing not only insomnia but also tossing and turning restlessly, with stifling sensations in the heart. Cheng Wuji cites the *Neijing*: "Where the pathology is high, promote emesis." Zhizi Chi Tang is given to emetic pathogens in the chest. Cheng comments: The Heart dislikes heat; extreme heat causes mental confusion, hence tossing and turning. He fails to realize that tossing and turning is not mental confusion, but rather stifling and vexation due to stagnated heat in the chest, resembling the urge to vomit. *Neitai Fangyi* states: This is not comparable to Jie Xiong or Pi syndromes; it should not be purged but treated with Zhizi Chi Tang to emetic and dissipate. A question arises: Can deficiency vexation tolerate repeated emesis? My answer: 'Deficiency' refers to righteous Qi deficiency; 'Vexation' refers to pathogenic excess. Pathogenic heat stagnating in the chest remains an indication for emesis, warranting repeated emetic therapy, just as indications for sweating or purging remain allow for repeated sweating or purging. I believe 'deficiency vexation' should not be viewed as true deficiency.)
