上为末。以水五升。煮取二升。去滓。温服八合。日三服。
经云。火逆下之。因烧针烦躁者。此汤主之。此证较上条稍轻。以元阳尚未至飞越。故
无取
蜀漆迅疾之性。急追以滋扰。但下后烧针误而再误因致烦躁。则此烦躁。非太阳病汗不出之
烦躁。又非少阴病吐利后之烦躁。是已具起卧不安之象。而为惊狂之渐。即伏亡阳之机。故
主桂枝入心助阳。而加甘草龙骨牡蛎。以安中而镇逆也。

按太阳病。得之八九日如疟状。发热恶寒。热多寒少。此当正邪胜复之关。一则虑其邪
之转
属。一则虑其正之已虚。不可不细辨矣。若其人不呕。清便欲自可。是邪不属里。一日二三
度发。是邪已外向。脉又微缓。则胃气足以敌邪。乃为欲愈之征。倘脉微而恶寒甚。此阴阳
俱虚
。不可更发汗更下更吐。恐误治伤阳。反生他变。若其人面色反有热色者。是为欲解未解之
象。以其不能得小汗以宣助阳气。致阳气虽不内扰。却怫郁于皮肤肌肉之间。其身必痒。此
明证也。故主桂麻而小其制。但得汗出而邪尽解矣。
Guizhi (Cinnamon Twig, 1 liang, bark removed) Gancao (Licorice Root, 2 liang, honey-fried) Muli (Oyster Shell, 2 liang, calcined) Longgu (Fossilized Bone, 2 liang)
Crush the above four herbs into powder. Add five sheng of water, boil to obtain two sheng of decoction, remove the dregs. Take eight ge warm per dose, three times a day.
The classics state: In cases where fire therapy caused adverse reactions, followed by purgation, and then burning needle therapy resulted in restlessness (Fan Zao), this decoction is indicated. This syndrome is slightly milder than the previous clause because the Primordial Yang (Yuan Yang) has not yet flown away and scattered, thus there is no need for the swift and violent nature of Shuqi (Coenogonium) to urgently pursue and disturb [the mind]. It is merely that errors in purgation and subsequent burning needle therapy led to restlessness through repeated mistakes. Therefore, this restlessness is not the restlessness without sweating seen in Taiyang disease, nor is it the restlessness after vomiting and diarrhea seen in Shaoyin disease; rather, it already exhibits signs of inability to sit or lie still, serving as a precursor to fright and mania (Jing Kuang), implying a latent mechanism of Yang collapse (Wang Yang). Hence, Guizhi is used as the chief herb to enter the Heart and assist Yang, supplemented with Gancao, Longgu, and Muli to calm the Middle Jiao and subdue rebellious Qi.
Guizhi (Cinnamon Twig, 1 liang 16 zhu, bark removed) Shaoyao (Peony Root) Shengjiang (Fresh Ginger) Gancao (Licorice Root) Mahuang (Ephedrae Herba, each 1 liang, nodes removed) Xingren (Prunus Armeniaca Seed, 24 seeds, soaked in hot water, skin and tips removed, excluding double-kernel ones) Dazao (Jujube Fruit, 4 pieces, torn open)
Take the above seven herbs, add five sheng of water, first boil Mahuang for one or two boils, remove the foam on the surface, then add the remaining herbs. Boil to obtain 1.8 sheng of decoction, remove the dregs, take warm.
Commentary: In Taiyang disease, after eight or nine days, the condition resembles malaria (Nue), with fever and aversion to cold, where heat predominates over cold. This occurs at a critical juncture of alternating victory and defeat between healthy Qi (Zheng Qi) and pathogenic factors (Xie Qi). One must worry about the pathogen transferring to other meridians, and also worry that the healthy Qi may be depleted; careful differentiation is essential. If the patient does not vomit and bowel movements are relatively normal, it indicates the pathogen has not entered the interior. If it occurs two or three times a day, it suggests the pathogen is moving outward. If the pulse is slightly slow (Wei Huan), it indicates sufficient Stomach Qi to resist the pathogen, which is a sign of impending recovery. However, if the pulse is fine (Wei) and aversion to cold is severe, this indicates deficiency of both Yin and Yang; one must not induce sweating, purge, or provoke vomiting, lest mis-treatment damage Yang and cause further complications. If the patient's face appears reddish, this is a sign of resolution that is incomplete. Because slight sweating cannot be achieved to ventilate and assist Yang Qi, causing Yang Qi, though not disturbing internally, to become constrained (Fu Yu) between the skin and muscles, the body will inevitably itch; this is clear evidence. Therefore, Guizhi Mahuang Ge Ban Tang (Cinnamon Twig and Ephedra Half-Dose Decoction) is used with a reduced dosage, so that upon achieving sweating, the pathogen will be completely resolved.
