（正解见中卷厥阴病中）
或问此条病。与前条同是胃中虚冷之证。何以不用四逆。余答云。胃中虚冷。饮水则哕。食谷欲呕。见证各异。
故不用四逆。投以吴茱萸汤为切当。盖呕为气逆。气逆者。必散之。吴茱萸辛苦。味重下泄。治呕为最。兼以生姜。
又治呕圣药。非若四逆中之干姜。守而不走也。武陵陈氏云。其所以致呕之故。因胃中虚。生寒。使温而不补。呕

上五条证（见原论中第五卷阳明病脉证并治法第八）

(The correct explanation can be found in the Middle Volume, Jueyin Disease chapter.)
A question was asked: This condition is identical to the previous one in that both present as deficiency-cold of the Stomach. Why is Si Ni Tang (Four Counterflow Decoction) not used? I replied: In cases of deficiency-cold of the Stomach, drinking water may induce hiccups (yue), and eating food may provoke vomiting; the manifested symptoms differ. Therefore, Si Ni Tang is not used; instead, Wu Zhu Yu Tang (Evodia Decoction) is administered as it is more appropriate. Vomiting is caused by rebellious Qi. When Qi rebels, it must be dispersed. Wu Zhu Yu (Fructus Evodiae) is acrid and bitter, with a heavy flavor that directs downward and drains; it is most effective for treating vomiting. Combined with Sheng Jiang (Rhizoma Zingiberis Recens), which is also a sacred remedy for vomiting, this differs from Gan Jiang (Rhizoma Zingiberis) in Si Ni Tang, which remains stationary and does not circulate outward. Chen of Wuling stated: The reason for vomiting is deficiency-cold generated within the Stomach. Using warming agents without tonification will not ultimately cure the vomiting. Therefore, Ren Shen (Radix Ginseng) is used to tonify the Middle Jiao, combined with Da Zao (Fructus Jujubae), to form a formula that harmonizes the Spleen. For the preceding condition, using this decoction resulted in cures in many cases, but occasionally some patients worsened after taking it. Thus, Cheng Wuji noted: One should seek another method for treating Upper Jiao conditions.
After sweating therapy for Shang Han (Cold Damage), the body and eyes turn yellow. The reason for this is that cold-dampness resides in the interior and has not resolved. It is considered inadvisable to use purgation; rather, one should seek treatment within the context of cold-dampness. (The "Shang Han" mentioned here refers to a Zhong Han [direct attack by cold] syndrome. If it were typical Shang Han, after sweating, the pathogenic heat would escape outward, so how could jaundice occur? Now, after sweating, the body and eyes turn yellow. The reason is that the patient inherently possesses cold-dampness in the interior and has additionally contracted cold pathogens on the exterior. After sweating, the exterior cold pathogens are expelled, but the interior cold-dampness remains unremoved, hence it is said "not resolved." Moreover, sweat is a Yang fluid, transformed from the Yang Qi of the Middle Jiao. After sweating, the Middle Qi becomes more deficient, and cold-dampness becomes more stagnant. The Spleen and Stomach are injured by cold-dampness, causing discoloration to appear externally. This differs from jaundice caused by damp-heat; therefore, it is said "do not purge," meaning bitter-cold purgative drugs should not be used. "Seek treatment within cold-dampness" implies that Zhang Zhongjing feared later physicians might treat this similarly to the "stagnant heat in the interior" condition described later. Books such as *Tiao Bian* and *Shang Lun* erroneously supplemented treatments with formulas like Yin Chen Hao Tang (Artemisia Capillaris Decoction) and Zhi Zi Bai Pi Tang (Gardenia and Phellodendron Bark Decoction), which is a grave error. Furthermore, since Zhang Zhongjing explicitly stated "do not purge," yet Yin Chen Hao Tang contains two liang of Da Huang (Radix et Rhizoma Rhei), is this not a purgative method? Thus, we know Zhang Zhongjing must have had another treatment method in mind, which later generations should interpret through careful consideration. Chang Qizhi in *Bu Wang Lun* suggested Wu Ling San (Five-Ingredient Powder with Poria); his discussion is relatively close to the original intent. ○ A question was asked: Dampness combined with heat causes stagnation and thus jaundice. Now, if combined with cold, why does jaundice occur? I replied: Cold-damp jaundice is like the rainy season in autumn and winter; plants that should not turn yellow also do, known as "cold jaundice." Wang Haicang stated: Yin Jaundice presents with cold limbs, sweating, and a deep pulse, resulting from dampness in the Taiyin Meridian. There are also cases with fever, where the body appears like smoked yellow, meaning the color is dark and dull like smoke. This is distinctly different from Yang Jaundice, which is bright orange-yellow. Treatment: If urination is free, use Shu Fu Tang (Aconite and Atractylodes Decoction). If urination is difficult but stool is loose, use Wu Ling San. ○ I observe that this clause likely belongs to the Taiyin Meridian due to bamboo slip misordering, but it is currently placed in the Yangming chapter; I shall temporarily follow Zhang Zhongjing's original arrangement.)
The above five conditions (see Original Treatise, Volume 5, Yangming Disease Pulse, Syndrome, and Treatment Methods, Chapter 8).
(Hu summarizes: All the above conditions are derived from Zhang Zhongjing's Taiyang and Yangming diseases. The Taiyang Meridian is the meridian of Cold Water. Therefore, when Wind-Cold-Damp pathogens invade from outside, they may directly strike the meridian. If the invasion is rapid, there is insufficient time for fever to develop, so symptoms such as headache or irritability/heat do not appear. Or, if the person's Yang Qi is originally deficient, even if the disease persists for a long time, it will not generate constrained heat. Additionally, Yangming Zhong Han (Cold Attack on Yangming) can result from cold air invading the chest area or from consuming cold foods. Because the person's Spleen and Stomach Qi is weak, constrained heat is not generated, resulting in a true Yin-cold syndrome. A question was asked: Why are there no Zhong Han conditions in Zhang Zhongjing's Shaoyang disease chapter? I replied: Shaoyang originates from Minister Fire. Minister Fire does not accept cold pathogens; therefore, there are no direct attack conditions. However, Yangming disease can involve cold because, although Yangming belongs to Dry Metal, the nature of metal is inherently cold. Another question was asked: If your statement is true, then Taiyin Wet Earth and Jueyin Wind Wood inherently contain cold within wind and dampness. As for Shaoyin governing Lord Fire, why are there relatively more Zhong Han conditions? I replied: The Qi of Lord Fire occupies the position of Heaven's Governance, corresponding to the Earthly Branches Zi and Wu. Wu clashes with Zi Water; how can there be no cold? The Classic states: The Qi of Lesser Fire is vigorous; the Qi of Greater Fire declines. Wu corresponds to Greater Fire, where fire energy declines, allowing cold to invade. Hence, at the Summer Solstice, which belongs to Wu, one Yin begins to arise. This is what is meant.)
