凡伤寒之呃,亦无非气逆之病,其有与杂证不同者,如仲景所言则其类也,然犹有未悉
及治有未备者,谨略如下∶
一、伤寒胃中虚冷等证,大约与前杂证相似,悉宜如前以温中等剂治之。或如仲景所言
胃中虚冷及饮水则哕等证,当以后条仲景法治之。
一、伤寒邪在表者,与里无涉,故无哕证。惟少阳证邪在半表半里之间,则寒热往来,
气为邪抑而哕逆者有之矣,宜柴陈煎主之,有寒者加丁香,有火者加黄芩;或小柴胡汤亦可
。
一、伤寒失下,邪入正阳明,内热之极,三焦干格,阴道不行而上冲作呃者,必宜去火
去闭,斯逆气得降而哕乃可愈。然必察邪之微甚,如无坚实胀满等证,而但以干涸燥热者,
宜白虎汤,或竹叶石膏汤,或泻心汤凉解之。若果有燥粪,大便闭结,胀满实坚俱全者,宜
三承气汤下之。
一、伤寒邪有未解,而用温补太过者,则其中焦气逆,最能为哕,惟安胃饮为最妙。若
气逆无火者,宜橘皮汤。若兼表邪未解者,宜柴陈煎。
一、伤寒误攻,或吐或下,或误用寒凉,以致脾肾胃气大虚大寒而发哕者,大为危候,
速当以前杂证温胃、理阴等法调治之,恐迟则无济于事也。
仲景曰∶阳明病,不能食,攻其热必哕,所以然者,胃中虚冷故也,以其人本虚,故攻
其热必哕。伤寒大吐大下之,极虚,复极汗出者,以其人外气怫郁,复与之水,以发其汗,
因得哕。所以然者,胃中虚冷故也。阳明病,不大便六七日,恐有燥屎,欲知之法,少与
小承气汤。汤入腹中,转失气者,此有燥屎,乃可攻之;若不转失气者,此但初头硬,
后必溏,不可攻之,攻之必胀满不能食也。欲饮水者,与水则哕。若胃中虚冷不能食者,饮
水则哕。按以上四条,皆言胃之虚寒也。虚寒者既不可攻,亦不可与水,则寒凉之药亦当忌
用可知。
论曰∶伤寒哕而腹满,视其前后,知何部不利,利之则愈。按此一条,即言哕之实邪也
。盖便有不利,则气有不达,下不达则上逆而出。故小便不利者,当利其水;大便不通者,
当通其便。
《要略》曰∶病患胸中似喘不喘,似呕不呕,似哕不哕,彻心中愦愦然无奈者,生姜半
夏汤主之。干呕哕,手足厥者,橘皮汤主之。哕逆者,橘皮竹茹汤主之。
张子和《吐式篇》云∶凡病在上者皆宜吐,然自胸以上大满大实,痰如胶漆,微汤微散
皆儿戏耳,若非吐法,病安能除?曾见病之在上者,诸医用药尽其技而不效,余以涌剂少少
用之,辄获微效,可见吐法必可用于上,宜乎其效之速也。按此吐法亦可治哕者,以其气得
伸而郁得散也,故凡气实而郁者,在子和之法亦所宜用。
凡伤寒引起的呃逆,无非都是气机上逆的病症。其中有些情况与内科杂病不同,如张仲景所论述的那样,但仍有未尽之处和治疗不够完备的地方,现简要陈述如下:
第一条:伤寒导致的胃中虚冷等证候,大致与前文所述的内科杂病相似,都应当像前文那样使用温中的方剂进行治疗。或者像张仲景所说,对于胃中虚冷以及饮水后引发呃逆(哕)等证候,应当采用下文提到的张仲景的方法治疗。
第二条:伤寒邪气在体表时,未波及里部,所以不会出现呃逆证候。只有少阳证的邪气在半表半里之间,出现寒热往来,气机被邪气抑制而导致呃逆的情况是存在的,适宜用柴陈煎为主方治疗;若兼有寒象加丁香,兼有火象加黄芩;或者小柴胡汤也可以使用。
第三条:伤寒因误用攻下法导致失下,邪气传入阳明经,内热极盛,三焦干涩格拒,阴液不通而上冲引发呃逆的,必须去除火热、解除闭结,这样逆气才能下降,呃逆才可痊愈。然而必须仔细辨别邪气的轻重,如果没有坚实胀满等实证,仅仅是干燥涸竭燥热的,适宜用白虎汤,或竹叶石膏汤,或泻心汤来清热解郁。如果确实有燥屎,大便闭结,胀满实坚等症状俱全的,适宜用三承气汤攻下。
第四条:伤寒邪气尚未解除,而过度使用温补药物的,会导致中焦气机上逆,最容易引发呃逆,此时以安胃饮最为巧妙。如果气逆而无火象的,适宜用橘皮汤。如果兼有表邪未解的,适宜用柴陈煎。
第五条:伤寒误用攻伐,或催吐或泻下,或误用寒凉药物,导致脾、肾、胃之气大虚大寒而引发呃逆的,属于非常危险的证候,应当迅速以前文内科杂病中温胃、理阴等方法调理治疗,恐怕延误时机就无济于事了。
张仲景说:阳明病,不能进食,如果攻其热必致呃逆,之所以如此,是因为胃中虚冷的缘故,因为病人本身体质虚弱,所以攻其热必致呃逆。伤寒经过大吐大下之后,正气极度虚弱,又出现极度汗出,因为病人外表气机怫郁,再给他喝水以发汗,因此导致呃逆。之所以如此,是因为胃中虚冷的缘故。阳明病,六七天不大便,担心有燥屎,想要知道是否有燥屎的方法,少量给予小承气汤。药汤进入腹中,如果转矢气(放屁),这是有燥屎,才可以攻下;如果不转矢气,这仅是开头硬,后面必定稀溏,不可攻下,攻下必然导致胀满不能进食。想喝水的人,给水则引发呃逆。如果是胃中虚冷不能进食的人,给水则引发呃逆。以上四条,都是讲胃的虚寒。虚寒既不可攻下,也不可给水,那么寒凉的药物也应当忌用,这是显而易见的。
论述说:伤寒呃逆且腹部胀满,观察前后二阴,知道哪一部不利,通利它即可痊愈。这一条,就是讲呃逆的实邪。大概是大便不利,气机就不能通达,下不达则上逆而出。所以小便不利的,应当利水;大便不通的,应当通便。
《金匮要略》说:病人胸中似喘非喘,似呕非呕,似呃非呃,心中烦乱无可奈何的,用生姜半夏汤主治。干呕呃逆,手足厥冷的,用橘皮汤主治。呃逆的,用橘皮竹茹汤主治。
张子和《吐式篇》说:凡是病在上部的都适宜用吐法,然而从胸部以上的大满大实,痰浊如胶漆般粘稠,微弱的汤剂或散剂如同儿戏一般,如果不是用吐法,病怎么能除去?曾见病在上部的,各位医生用药尽其技艺却无效,我少量使用涌吐剂,往往获得微小疗效,可见吐法必定可用于上部,其见效迅速也是理所当然的。按此吐法也可以治疗呃逆,因为气得以舒展而郁结得以消散,所以凡是气实而郁结的,按照张子和的方法也是适宜使用的。
Any hiccups (e, hiccup) caused by Shanghan (Cold Damage) are essentially disorders of rebellious Qi. Some cases differ from miscellaneous diseases, as discussed by Zhang Zhongjing, yet there remain omissions and incomplete treatments. The following is a brief summary:
First, conditions such as deficiency-cold in the stomach caused by Shanghan are roughly similar to those in miscellaneous diseases mentioned previously. They should all be treated with warming middle-jiao formulas as described earlier. Or, for conditions like deficiency-cold in the stomach and hiccups induced by drinking water, as stated by Zhang Zhongjing, one should follow the methods of Zhang Zhongjing detailed in the subsequent paragraphs.
Second, when the pathogen of Shanghan is at the exterior level and does not involve the interior, hiccups do not occur. However, in Shaoyang syndrome, where the pathogen is between the exterior and interior, causing alternating chills and fever, hiccups may occur due to Qi being suppressed by the pathogen. In such cases, Chaichen Decoction (Chaichen Jian) is indicated; add Dingxiang (Clove) if cold is present, or Huangqin (Scutellaria Root) if heat/fire is present; alternatively, Xiaochaihu Tang (Minor Bupleurum Decoction) may also be used.
Third, if Shanghan is mishandled by purgation, allowing the pathogen to enter the Yangming stage, extreme internal heat may cause dryness and obstruction in the Sanjiao (Triple Burner), blocking Yin fluids and causing upward rushing that triggers hiccups. It is essential to clear heat and resolve obstruction so that rebellious Qi descends and hiccups cease. One must carefully assess the severity of the pathogen. If there are no signs of firmness, distension, or fullness, but only dryness and燥热 (dry-heat), Baihu Tang (White Tiger Decoction), Zhuyeshi Gao Tang (Bamboo Leaf and Gypsum Decoction), or Xiexin Tang (Drain the Epigastrium Decoction) can be used to cool and resolve. If there is indeed dry feces, constipation, and complete symptoms of distension, fullness, firmness, and excess, then the three Chengqi Decoctions (San Chengqi Tang) should be used to purge.
Fourth, if Shanghan pathogens are unresolved and excessive warming and tonifying agents are used, it leads to rebellious Qi in the Middle Jiao, most likely causing hiccups. Anwei Yin (Stomach-Anning Infusion) is the most effective formula here. If Qi rebellion occurs without heat, Jupi Tang (Tangerine Peel Decoction) is suitable. If accompanied by unresolved exterior pathogens, Chaichen Decoction is appropriate.
Fifth, if Shanghan is mistakenly attacked via emesis or purgation, or if cold-cooling herbs are misused, resulting in severe deficiency and cold of the Spleen, Kidney, and Stomach Qi leading to hiccups, this is a critical condition. Immediate treatment with warming Stomach or regulating Yin methods, as described in previous miscellaneous disease sections, is required. Delay may render treatment ineffective.
Zhang Zhongjing stated: "In Yangming disease, inability to eat, attacking the heat will inevitably cause hiccups. The reason is deficiency-cold in the stomach. Because the person is originally deficient, attacking the heat will inevitably cause hiccups." "After severe vomiting and purging in Shanghan, leading to extreme deficiency, followed by profuse sweating, because the external Qi is constrained (Fu Yu), giving water to induce sweating causes hiccups. The reason is deficiency-cold in the stomach." "In Yangming disease, no bowel movement for six or seven days, suspecting dry feces, the method to verify is to give a small amount of Xiao Chengqi Tang. If after ingestion, flatus is passed, this indicates dry feces, and purging can proceed; if no flatus is passed, the stool is merely hard at the beginning and loose later, purging is contraindicated. Purging will cause distension and inability to eat." "Those desiring water who are given water develop hiccups. Those with deficiency-cold in the stomach unable to eat who are given water develop hiccups." These four passages all discuss deficiency-cold of the stomach. Since deficiency-cold cannot be purged nor can water be freely administered, it is evident that cold-cooling medicines should also be avoided.
The treatise states: "Shanghan with hiccups and abdominal fullness: observe the anterior and posterior orifices to determine which is obstructed; unblocking it will cure the condition." This passage refers to excess pathogens causing hiccups. Generally, if defecation is obstructed, Qi cannot descend; failure to descend leads to upward rebellion. Therefore, if urination is obstructed, diuresis is indicated; if defecation is obstructed, purgation is indicated.
Jingui Yaolue states: "When patients feel like panting but do not pant, like vomiting but do not vomit, like hiccuping but do not hiccup, and feel profoundly distressed and helpless in their hearts, Shengjiang Banxia Tang (Ginger and Pinellia Decoction) is the primary treatment. For dry heaves and hiccups with cold extremities, Jupi Tang (Tangerine Peel Decoction) is indicated. For hiccups, Jupi Zhuru Tang (Tangerine Peel and Bamboo Shavings Decoction) is indicated."
Zhang Hezi's "Chapter on Emesis" states: "For diseases located in the upper body, emesis is generally appropriate. However, for severe fullness and excess above the chest, with phlegm-turbidity as sticky as glue, mild decoctions or powders are trivial. Without the emetic method, how can the disease be removed? I have seen cases where physicians exhausted their skills with drugs for upper-body diseases without effect, whereas my use of strong emetics in small doses often yielded slight effects. This shows that emesis is certainly applicable to upper-level diseases, explaining its rapid efficacy." According to this, the emetic method can also treat hiccups, as it allows Qi to extend and stagnation to dissipate. Thus, for conditions characterized by excess Qi and stagnation, Zhang Hezi's method is also suitable.
