答曰。经云。两感者死不治。一日太阳与少阴俱病。头痛发热。恶寒口干。烦满而渴。
太阳者腑
也。自背俞。而入。人之所共知。少阴者脏也。自鼻息而入。人所不知也。鼻气通于天。故
寒邪无形之气。从鼻出入。肾为水也。水流湿。故肾受之。经曰。伤于湿者。下先受之。同
气相求耳。又云天之邪气感则害人五脏以是知内外两感。脏腑俱病。欲表之。则有里。欲下
之。则有表。表里既不能一治。故死矣。故云两感者不治。然所禀有虚实。所感有浅深。虚而
感之深者必死。实而感之浅者。犹或可治。治之而不救者有矣。夫未有不治。而获生者也。
予尝用此。间有生者。十得二三。故立此方。以待好生君子用之。解利两感神方。

回答说：医经中记载，两感病（表里两经同时受邪）属于死证，难以治愈。第一天太阳经与少阴经同时发病，出现头痛、发热、恶寒、口干、心中烦闷胀满且口渴的症状。
太阳经属于腑（此处指足太阳膀胱经），病邪从背部的俞穴进入，这是人们所共知的常识。少阴经属于脏（此处指足少阴肾经），病邪从鼻息进入，这是人们所不知晓的。鼻气上通于天，所以无形之寒邪随呼吸从鼻出入。肾属水，水性就湿，所以病邪归于肾。医经说：“伤于湿邪者，下部先受之。”这是因为同气相求的缘故。又说：“天之邪气感人，会伤害五脏。”由此可知，内外两感导致脏腑俱病。想要解表发汗，则顾虑里有病；想要攻下治里，则顾虑表未解。既然表里不能单独治疗，所以会导致死亡。因此说两感病是不治之症。然而，人的体质禀赋有虚实之分，感受病邪有深浅之别。体质虚弱而感受病邪深重的必然死亡；体质充实而感受病邪浅表的，或许还可以治疗。也有经过治疗却未能挽救的情况。但是，如果不进行治疗而能获救生存的例子是没有的。我曾经使用这个方子，偶尔也有救活的患者，十人中能救活二三人。所以我制定这个方子，以供喜好救人的君子使用。此方名为“解利两感神方”。
药物组成：防风、羌活、独活、防己、黄芩、黄连、苍术、白术、甘草（炙）、细辛（去土，各三钱）；知母（生用）、川芎、地黄（各一两）。
以上药材切碎。每次服用半两，加水二盏，煎煮至一盏半，滤去药渣，取澄清药液一大盏，趁热饮用。如果服药后症状未解，可再次服用。服用三四盏后症状解除也可以。病愈即停药。如果还有残留症状，均根据张仲景的随经法治则进行处理。
清气位于身体的上部，属阳，属火。离卦（象征心/火）中的阴气下降，午后一阴初生，这对应于心生成血液的过程，所以说“清气为荣”（营气）。
浊气位于身体的下部，属阴，属水。坎卦（象征肾/水）中的阳气上升，子时过后一阳初生，这对应于肾阳升举推动的作用，所以说“浊气为卫”（卫气）。地上的浊气本应不升，但地之清气能升；能升举阳气使之向上。天上的清气本应不降，但天之浊气能降，被六阴之气驱赶而下沉。医经说：“地气上升化为云，天气下降化为雨。雨源于地气，云源于天气。”说的就是这种情况吧。
Answer: The Classics state that "Lianggan" (Simultaneous involvement of exterior and interior meridians) is a fatal condition and difficult to treat. On the first day, both the Taiyang (Greater Yang) and Shaoyin (Lesser Yin) meridians are affected, presenting with headache, fever, aversion to cold, dry mouth, vexation, fullness, and thirst.
The Taiyang meridian belongs to the Fu organs (specifically the Foot-Taiyang Bladder), where pathogens enter from the Shu points on the back; this is common knowledge. The Shaoyin meridian belongs to the Zang organs (specifically the Foot-Shaoyin Kidney), where pathogens enter through nasal respiration; this is unknown to many. Nasal qi connects with Heaven, thus formless cold pathogenic qi enters and exits through the nose. The Kidney corresponds to Water; water flows towards dampness, therefore the Kidney receives it. The Classics say, "Those injured by Dampness suffer first in the lower part." This is due to the attraction of similar energies (Tongqi Xiangqiu). It is also stated, "Heavenly pathogenic qi affecting humans harms the Five Zang organs." From this, we know that simultaneous external and internal invasion leads to disease in both Zang and Fu organs. To release the exterior, one worries about the interior pathology; to purge the interior, one worries about the unresolved exterior. Since the exterior and interior cannot be treated separately, death ensues. Hence, it is said that Lianggan is incurable. However, constitutional endowment varies between deficiency and excess, and the depth of pathogenic invasion varies. Those who are deficient and deeply invaded will certainly die; those who are robust and lightly invaded may still be treatable. There are cases where treatment fails to save the patient. Yet, there is no case of survival without treatment. I have occasionally used this prescription, saving two or three out of ten patients. Therefore, I established this formula for benevolent physicians to use. It is named the "Divine Formula for Resolving Lianggan."
Ingredients: Fangfeng (Saposhnikoviae Radix), Qianghuo (Notopterygii Rhizoma et Radix), Duhuo (Angelicae Pubescentis Radix), Fangji (Stephaniae Tetrandrae Radix), Huangqin (Scutellariae Radix), Huanglian (Coptidis Rhizoma), Cangzhu (Atractylodis Rhizoma), Baizhu (Atractylodis Macrocephalae Rhizoma), Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried), Xixin (Asari Radix et Rhizoma, cleaned of soil, each 3 qian); Zhimu (Anemarrhenae Rhizoma, raw), Chuanxiong (Ligusticum Chuanxiong Rhizoma), Dihuang (Rehmanniae Radix Praeparata, each 1 liang).
Crush the above herbs. Take 0.5 liang per dose, add 2 zhan of water, decoct until 1.5 zhan remains. Strain to obtain a large zhan of clear liquid. Drink hot. If symptoms do not resolve, administer again. Resolution may occur after 3-4 zhan. Stop when the disease is cured. If residual symptoms persist, treat according to Zhang Zhongjing's principles of following the meridian patterns.
Clear Qi resides in the upper part of the body, corresponding to Yang and Fire. The Yin within the Li trigram (symbolizing Heart/Fire) descends. Afternoon marks the generation of one Yin, which corresponds to the Heart generating Blood. Thus, it is said that "Clear Qi constitutes Ying (Nutritive Qi)."
Turbid Qi resides in the lower part of the body, corresponding to Yin and Water. The Yang within the Kan trigram (symbolizing Kidney/Water) ascends. After midnight (Zi hour) marks the generation of one Yang, which corresponds to the rising action of Kidney Yang. Thus, it is said that "Turbid Qi constitutes Wei (Defensive Qi)." Earth's turbidity does not ascend naturally, but Earth's clarity can ascend; it can raise Yang Qi upwards. Heaven's clarity does not descend naturally, but Heaven's turbidity can descend, driven downward by the Six Yin energies. The Classics state, "Earthly Qi rises to become Clouds; Heavenly Qi descends to become Rain. Rain originates from Earthly Qi; Clouds originate from Heavenly Qi." This is what is meant.
