下之。盖谓燥屎在胃中而谵语。其风邪在表而汗出。其燥屎在胃则当下。过太阳。无表症。而结于
里。乃可下之。此言过太阳经而结于胃。成里症者也。果如成氏十三日再传经尽谓之过经。则燥
屎在胃。必待十三日乃可下乎。于此则注曰。须过太阳经无表症。乃可下之。则与再传经尽谓之过
经。自相矛盾矣。太阳篇曰。太阳病。过经十余日。反二三下之。后四五日。柴胡症仍在者。先与
小柴胡汤。盖谓过太阳经。无太阳表症。然里症未具。本未可下。反二三下之。后四五日。尚有
少阳之柴胡症者。亦须与小柴胡汤。此专言过太阳经者也。霍乱篇曰。下利后当便硬。硬则能食者
愈。今反不能食。到后经中。颇能食。复过一经。能食。过之一日。当愈。不愈者。不属阳明也。
使用下法。大概是指燥屎(肠道内干结的粪便)在胃中导致谵语(神志不清,胡言乱语)。风邪在体表导致汗出。如果燥屎在胃中,就应当使用下法。病邪经过太阳经后,没有表证,而结聚于里,才可以采用下法。这是说病邪经过太阳经后结聚在胃中,形成里证的情况。如果像成无己所说,十三日再次传经结束称为“过经”,那么燥屎在胃中,一定要等到十三日才能使用下法吗?在此处的注释中说:必须经过太阳经且没有表证,才可以采用下法。这就与“再次传经结束称为过经”的说法自相矛盾了。《太阳篇》说:太阳病,经过十余日,反而进行了两三次攻下治疗,之后过了四五天,柴胡证(少阳病证候)仍然存在的话,先给予小柴胡汤。大概是指经过太阳经后,没有太阳表证,但是里证尚未具备,本来不可以使用下法,反而进行了两三次攻下治疗,之后过了四五天,还有少阳的柴胡证的话,也必须给予小柴胡汤。这是专门讲述经过太阳经的情况。《霍乱篇》说:下利(腹泻)之后大便应当变硬,大便变硬并且能进食的是痊愈的表现。现在反而不能进食,到了下一个经气运行的周期中,稍微能进食了,又经过一个经气运行周期,能够进食,超过了一天,应当痊愈。如果不痊愈的,就不属于阳明病。
Administer the purgative method. This refers to dry feces (hardened stool in the intestines) residing in the stomach causing delirium (incoherent speech due to mental confusion). Wind-pathogen is on the exterior causing sweating. If dry feces are in the stomach, purgation should be employed. After passing through the Taiyang (Greater Yang) channel, if there is no exterior syndrome but pathogenic factors have consolidated internally, then purgation may be used. This statement refers to pathogenic factors passing through the Taiyang channel and consolidating in the stomach, forming an interior syndrome. If, as Cheng Wuji stated, the completion of a second cycle of transmission after thirteen days is termed "passing the channel" (Guojing), does it mean that one must wait until the thirteenth day to use purgation when dry feces are in the stomach? The commentary here states: "One must pass through the Taiyang channel without exterior symptoms before purgation can be used." This contradicts the definition of "passing the channel" as the completion of a second cycle of transmission. The Taiyang Chapter states: "In Taiyang disease, after more than ten days, if the patient has been incorrectly subjected to purgation two or three times, and after another four or five days, the Chaihu syndrome (Shaoyang disease pattern) still persists, first administer Xiao Chaihu Tang (Minor Bupleurum Decoction)." This implies that after passing through the Taiyang channel, although there is no Taiyang exterior syndrome, the interior syndrome is not yet fully formed, so purgation was originally contraindicated; yet, incorrect purgation was performed two or three times. After another four or five days, if Shaoyang Chaihu symptoms persist, Xiao Chaihu Tang must still be administered. This specifically discusses the scenario of passing through the Taiyang channel. The Huoluan (Huo Luan / Cholera-like Disease) Chapter states: "After diarrhea, the stool should become hard. If it becomes hard and the patient can eat, recovery will occur. Now, if the patient cannot eat, but later, during the next meridian cycle, begins to eat slightly, and then after another full cycle, eats normally, and this state continues for one day, recovery should occur. If recovery does not occur, it does not belong to the Yangming (Yang Brightness) category."
