姜、葱各半斤，煎汤一斛，倾大盆中，用小板一块，横加盆上，令患人坐卧其上蒸之，
外以席被围定，露其口鼻，外可进发汗药。
朔方严寒之地，腠理闭密，汗不易泄，故行此法。
盖姜、葱能通腠理，作汤以蒸之，则表疏而汗易泄，乃外合之兵也。
龙骨 牡蛎 糯米（各等分，为末）
服发汗药，出汗过多者，以此粉扑之。
汗多有亡阳之戒，故用龙骨、牡蛎之涩以固脱；入粳米者，取其粘腻云尔，乃卫外之兵
也！
期门，穴名，妇人屈乳头向下尽处是穴。乳小者，以一指为率。陷中有动脉，刺之令病
人吸五吸，停针良久出针。
妇人热入血室，胁下满如结胸状，谵语者，此刺主之。
妇人伤寒发热，月事适来，血室空虚，邪热乘虚而入，名曰热入血室。血室，冲脉也。
胁下满如结胸状者，冲脉贯肝膈，至胸中而散，故所过皆病也；谵语者，邪热内盛而神明乱
也。期门，肝之募穴，刺之出血，乃随其实而泻之，兵之迎
羌活 独活 防己 防风 苍术 白术 黄连 黄芩 细辛 川芎 甘草（各三钱） 生
地黄（一两） 知母（三钱）
伤寒两感者，此方主之。
两感者，一日太阳与少阴俱病，谓有太阳证之头疼、身热、脊强，而又有少阴证之口干
、烦满而渴也；二日则阳明与太阴俱病，谓有阳明证之身热、谵语，而又有太阴证之腹满、
不欲食也；三日则少阳与厥阴俱病，谓有少阳证之耳聋、胁痛，而又有厥阴证之囊缩、厥逆
也。凡此两感之证，欲汗之则有里，欲下之则有表，表里不能一治，故《内经》、仲景皆称
必死而无活法。易老意曰∶证虽有表里之殊，而无阴阳之异，传经者皆为阳邪，一于升阳散
热、滋养阴脏，则感之浅者尚或可平矣。经曰∶气薄则发泄，故用羌活、独活、防风、苍术
、细辛、川芎之气薄者，以升发其传经之邪；又曰∶寒胜热，故用黄连、黄芩、防己、生地
、知母之寒苦者，以培养其受伤之阴。以升散诸药而臣以寒凉，则升者不峻；以寒凉诸药而
君以升散，则寒者不滞。白术、甘草，脾家药也，用之者，所以益其脾胃而建中营之帜尔。
呜呼！于不可治之中，而求为可治之策，大羌活者，其万死一生之兵乎！
用生姜和葱白各半斤，煎煮成一斛汤液，倒入大盆中。取一块小板横架在盆口上，让患者坐卧在板上进行熏蒸。外部用席子和被子围好固定，只露出口鼻，同时可以在外部服用发汗药物。
北方严寒之地，人体腠理（皮肤毛孔及纹理）闭合致密，汗液不易排出，所以采用这种方法。因为生姜和葱白能够通达腠理，用汤液熏蒸，则体表疏松而汗液容易排出，这属于“外合之兵”（辅助外部治疗的策略）。
龙骨、牡蛎、糯米（各等分，研成粉末）。
服用发汗药后，出汗过多的患者，用此粉末扑洒在身上。
出汗过多有导致亡阳（阳气脱失）的危险，所以使用龙骨、牡蛎的收敛固涩作用来固摄脱失的阳气；加入粳米，是取其粘腻的性质，这属于“卫外之兵”（保卫体表的策略）。
期门穴，穴位名称，位于女性乳头直下，肋骨尽处即是该穴。如果乳房较小，以一根手指的宽度为界限。穴位凹陷中有动脉跳动，针刺时让病人吸气五次，留针较长时间后出针。
妇女患热邪陷入血室（指子宫或冲脉），胁下胀满如同结胸证的样子，伴有胡言乱语，此症以此穴针刺为主治。
妇女患伤寒发热，月经适逢来潮，血室空虚，邪热乘虚而入，称为热入血室。血室，即冲脉。
胁下胀满如同结胸证的样子，是因为冲脉贯穿肝脏和膈肌，上行至胸中散开，所以经过的地方都会发病；胡言乱语，是因为邪热内盛导致神明混乱。期门穴是肝经的募穴，针刺使其出血，这是顺应其实证而进行泻法，是军队正面迎击敌人的策略。
羌活、独活、防己、防风、苍术、白术、黄连、黄芩、细辛、川芎、甘草（各三钱），生地黄（一两），知母（三钱）。
伤寒两感证，以此方主治。
所谓两感证，第一天太阳经与少阴经同时发病，表现为既有太阳经证的头痛、身热、脊背强直，又有少阴经证的口干、烦闷且口渴；第二天阳明经与太阴经同时发病，表现为既有阳明经证的身热、胡言乱语，又有太阴经证的腹部胀满、不想进食；第三天少阳经与厥阴经同时发病，表现为既有少阳经证的耳聋、胁痛，又有厥阴经证的睾丸收缩、四肢厥冷。凡是这种两感证，想要发汗则有里证牵制，想要攻下有表证牵制，表里不能同时治疗，所以《内经》和张仲景都称其为必死之症而无活法。李东垣（易老）认为：症状虽然有表里之分，但没有阴阳的本质差异，传经而来的都是阳邪，只要致力于升阳散热、滋养阴脏，那么感受邪气较浅的或许还可以平复。经文说：气味薄的药物能发散发泄，所以使用羌活、独活、防风、苍术、细辛、川芎这些气味薄的药物，来升发透散传入经络的邪气；又说：寒能胜热，所以使用黄连、黄芩、防己、生地黄、知母这些性味寒苦的药物，来培养受损的阴液。用升散类药物作为臣药配合寒凉药，则升散之力不猛烈；用寒凉类药物作为君药配合升散药，则寒凉之性不凝滞。白术、甘草是调理脾胃的药物，使用它们，是为了补益脾胃并建立中焦营卫的旗帜。唉！在不可治之中寻求可治的策略，大羌活汤，大概是那万死一生中的救命良方吧！
Take half a jin of ginger and half a jin of scallion (Congbai, Allii Fistulosi Bulbus), decoct them in one hu (a unit of volume) of water, pour the liquid into a large basin. Place a small wooden board horizontally across the basin, and let the patient sit or lie on the board to undergo steam therapy. Surround the area with mats and quilts to retain heat, leaving only the mouth and nose exposed, while simultaneously administering diaphoretic medicines externally.
In the severe cold regions of the north, the couli (pores and skin texture) are closed and dense, making it difficult for sweat to be excreted; therefore, this method is employed. Since ginger and scallion can unblock the couli, steaming with the decoction loosens the exterior and facilitates sweating. This strategy is referred to as "external reinforcement troops."
Longgu (Dragon Bone, Os Draconis), Muli (Oyster Shell, Concha Ostreae), and Nuomi (Glutinous Rice, Oryza Sativa Glutinosa) (in equal parts, ground into powder).
For patients who have sweated excessively after taking diaphoretic medicines, apply this powder to the body.
Excessive sweating carries the warning of Wang Yang (collapse of Yang Qi); therefore, the astringent properties of Longgu and Muli are used to secure and prevent collapse. The addition of Jingmi (Japonica Rice, Oryza Sativa Japonica) is due to its sticky nature. This strategy is referred to as "defensive troops."
Qimen (LR-14, Gate of Expectation), an acupoint name, is located at the end of the rib cage directly below the nipple in women. If the breast is small, use one finger's width as the standard. There is a pulsating artery in the depression. When needling, instruct the patient to inhale five times, retain the needle for a considerable period, and then withdraw it.
For women suffering from Re Ru Xue Shi (Heat Entering the Blood Chamber), characterized by fullness in the hypochondrium resembling Jie Xiong (Chest Binding Syndrome) and delirium, this acupoint is the primary treatment via needling.
When a woman suffers from Shang Han (Cold Damage) with fever, and her menstruation happens to begin, the Blood Chamber becomes empty, allowing pathogenic heat to enter vacuously. This is named Re Ru Xue Shi (Heat Entering the Blood Chamber). The Blood Chamber refers to the Chong Mai (Penetrating Vessel).
The fullness in the hypochondrium resembling Jie Xiong occurs because the Chong Mai passes through the Liver and Diaphragm, dispersing in the chest; thus, all areas it traverses become diseased. Delirium occurs because excessive internal pathogenic heat confuses the Shen (Spirit). Qimen is the Mu-Point (Alarm Point) of the Liver. Needling to induce bleeding follows the principle of draining excess according to the syndrome, akin to troops engaging the enemy head-on.
Qianghuo (Notopterygii Rhizoma et Radix), Duhuo (Angelicae Pubescentis Radix), Fangji (Stephaniae Tetrandrae Radix), Fangfeng (Saposhnikoviae Radix), Cangzhu (Atractylodis Rhizoma), Baizhu (Atractylodis Macrocephalae Rhizoma), Huanglian (Coptidis Rhizoma), Huangqin (Scutellariae Radix), Xixin (Asari Radix et Rhizoma), Chuanxiong (Ligustici Chuanxiong Rhizoma), and Gancao (Glycyrrhizae Radix et Rhizoma) (each 3 qian), Sheng Dihuang (Rehmanniae Radix Recens) (1 liang), and Zhimu (Anemarrhenae Rhizoma) (3 qian).
This formula is indicated for Liang Gan (Simultaneous Infection of Exterior and Interior) in Shang Han (Cold Damage).
"Liang Gan" refers to the simultaneous disease of two meridians. On the first day, Taiyang (Greater Yang) and Shaoyin (Lesser Yin) are both affected, presenting with Taiyang symptoms such as headache, fever, and stiffness of the spine, alongside Shaoyin symptoms such as dry mouth, irritability, fullness, and thirst. On the second day, Yangming (Bright Yang) and Taiyin (Greater Yin) are both affected, presenting with Yangming symptoms such as fever and delirium, alongside Taiyin symptoms such as abdominal fullness and loss of appetite. On the third day, Shaoyang (Lesser Yang) and Jueyin (Terminal Yin) are both affected, presenting with Shaoyang symptoms such as deafness and hypochondriac pain, alongside Jueyin symptoms such as contraction of the testicles and cold extremities. In such Liang Gan syndromes, inducing sweat is contraindicated due to interior involvement, while purging is contraindicated due to exterior involvement; since the exterior and interior cannot be treated simultaneously, both the *Neijing* (Classic of Internal Medicine) and Zhang Zhongjing state that these cases are invariably fatal without a cure. However, Li Dongyuan (Yi Lao) reasoned: although symptoms differ between exterior and interior, there is no fundamental difference in Yin and Yang; transmitted pathogens are all Yang evils. By focusing on raising Yang and dissipating heat, and nourishing Yin organs, those with shallow infection may potentially recover. The classic states: "Thin qi causes excretion/dissipation"; therefore, thin-qi herbs like Qianghuo, Duhuo, Fangfeng, Cangzhu, Xixin, and Chuanxiong are used to raise and disperse transmitted pathogens. It also states: "Cold overcomes heat"; therefore, bitter-cold herbs like Huanglian, Huangqin, Fangji, Sheng Dihuang, and Zhimu are used to nurture the injured Yin. Using ascending and dispersing herbs as ministers to cold-cooling herbs prevents the ascending action from being too harsh; using cold-cooling herbs as sovereigns to ascending herbs prevents the cold nature from becoming stagnant. Baizhu and Gancao are spleen-stomach herbs; they are used to benefit the spleen and stomach and establish the banner of the Middle Jiao Ying (Nutritive Qi). Alas! Seeking a curable strategy within the incurable, Da Qianghuo Tang (Major Notopterygium Decoction) is perhaps the life-saving remedy amidst ten thousand deaths.
