寒治
先其
鳌按、热药不但附子。一切姜、桂皆然
阳俱虚。或阴虚更甚于阳者。以热药治之。
原以补阳。余曾见一医治一阴虚之妇。其医
不痊。且愈多枯燥象。可见人参补阳。虽有益
足。若但与补阳药用之。未见其有济也。读书
【禁忌】经疏曰。一切阳症。火症。热症。阴虚内热血液衰少症。均忌。
味辛。性热。有毒。即附子之母。
【主治】主风痹。血痹。半身不遂诸风。除寒冷。温养脏腑。去心下坚痞。感寒腹痛。
（
元素） 除寒湿行经。散风邪。破诸积冷毒。（李杲） 补命门不足。肝风虚。（好古）
【归经】入脾命门二经。为助阳退阴之品。（通行十二经络功同附子而稍缓）
【前论】宗 曰。补虚寒须用附子。去风即多用川乌。大略如此。 时珍曰。附子性重
滞。
鳌按、乌头以出川彰明者为上。故加川字以别草乌头也。附子即附生于乌头者。故亦以

竟不可用也。不然。仲景白通四逆真武等汤。何为用之哉。丹溪法重滋阴。故每偏诋阳药。
非平允之说也。
【性味】味道辛、甘。性质大热。有大毒。完全禀受地中火土燥烈之气，兼得天之热气以生长。沉降作用多于上升作用。
浮、中、沉三脉无所不到。属于阳中之阴。以地胆为引经药。畏忌蜈蚣。畏惧防风、黑豆、甘草、黄芩、人参、童便（儿童尿液）。忌讳豆豉汁。得到川椒、食盐后，能引导药力下行，直达命门。
【主治】主要治疗风寒引起的咳嗽气逆邪气。寒湿导致的痿证。筋脉拘挛、膝部疼痛。不能行走。破除症坚积聚和血瘕。金疮（金属利器造成的创伤）。
（出自《本经》）治疗腰脊部的风寒。香港脚（脚气病）冷弱。心腹冷痛。霍乱转筋。下痢赤白。坚固肌肉骨骼。又能堕胎，被称为“百药长”。
（原文此处有缺漏，推测涉及腹部寒冷、阴阳失调、久聋等症。）
【归经】入命门、三焦二经。兼入脾、肾、膀胱三经。是回阳救逆、退除阴寒的药物。（兼有补剂功效，专门补益命门相火）
【前论】虞抟说：附子禀赋雄壮之质，能引导补气药行于十二经脉，以追回并恢复散失的元阳；引导补血药进入……（原文残缺，推测意为进入血脉或相关经络），祛除……（原文残缺），阳益……（原文残缺），传遍……（原文残缺），待……（原文残缺），之即……（原文残缺），药格不……（原文残缺），也。
鳌按（作者评论）：热药不仅仅是附子，一切姜、桂皆然。若阳气俱虚，或者阴虚比阳虚更严重的情况，用热药治疗……（原文残缺）。原本是用来补阳的。我曾见过一位医生治疗一位阴虚的妇女，那位医生……（原文残缺）没有痊愈，而且出现更多干燥枯槁的现象。可见人参补阳，虽然有益处充足，但如果只与补阳药用在一起使用，未见其有帮助。读书……（原文残缺）。
【禁忌】缪希雍在《经疏》中说：一切阳证、火证、热证、阴虚内热、血液衰少的病症，均忌用。
【川乌】
味道辛。性质热。有毒。是附子的母药。
【主治】主要治疗风痹、血痹、半身不遂等各种风证。除去寒冷感。温养脏腑。去除心下坚痞。感受寒邪引起的腹痛。
（出自李杲/洁古）除去寒湿，通行经络。疏散风邪。破除各种积冷毒。（出自李杲）补益命门不足。肝风虚。（出自好古/王好古）
【归经】入脾、命门二经。是助阳退阴的药物。（通行十二经络的功效同附子，但稍缓和）
【前论】宗（推测为某医家，原文可能缺字，如张元素或李杲等，此处依原文保留“宗”）说：补虚寒必须用附子，祛风则多用川乌。大致如此。
时珍（李时珍）说：附子性质重滞。
鳌按：乌头以四川彰明县出产的为上品，所以加“川”字以区别于草乌头。附子是附着生长在乌头上的子根，所以也以川产……（原文残缺，推测为物为佳）。
虽然暑……（原文残缺）又……（原文残缺）竟然不可用吗？不然的话，张仲景的白通汤、四逆汤、真武汤等，为什么使用它们呢？丹溪（朱震亨）法重视滋阴，所以常常偏颇地诋毁阳药。这不是公平允当的说法。
[Properties and Flavors] Pungent and sweet in taste. Extremely hot in nature. Highly toxic. It completely inherits the dry, hot, and fierce qi of fire and earth from within the ground, and grows by combining with the hot qi of heaven. Its descending action is greater than its ascending action.
It reaches all levels of floating, middle, and deep pulses. It belongs to yin within yang. Di Dan (Borneol) serves as its guiding herb. It is incompatible with centipede (Wugong). It fears Fangfeng (Saposhnikovia Root), Heidou (Black Soybean), Gancao (Licorice Root), Huangqin (Scutellaria Root), Renshen (Ginseng Root), Tongbian (Child's Urine), and Xijiao (Rhinoceros Horn - *note: modern substitutes used*). It is contraindicated with Douzhi (Fermented Soybean Juice). When combined with Chuanjiao (Sichuan Pepper) and Shiyans (Salt), it can guide the medicinal power downward, reaching directly to the Mingmen (Gate of Life).
[Indications] Primarily treats wind-cold cough and rebellious qi due to pathogenic factors. Treats flaccidity syndrome caused by cold-dampness. Treats tendon contraction and knee pain, inability to walk. Breaks up masses, accumulations, and blood stasis (Xuejia). Treats metal weapon injuries (Jinchuang).
(From *Shennong Ben Cao Jing*) Treats wind-cold in the lower back and spine. Treats cold weakness of Hongxiangjiao (Beriberi/Foot Qi). Treats cold pain in the heart and abdomen. Treats Huoluan (cholera-like syndrome) with tendon spasms. Treats dysentery with red and white discharge. Strengthens muscles and bones. It can also induce abortion and is known as the "Chief of Hundred Medicines."
(Text here has omissions, likely referring to abdominal cold, yin-yang imbalance, and chronic deafness.)
[Meridian Tropism] Enters the Mingmen and Sanjiao meridians. Also enters the Spleen, Kidney, and Bladder meridians. It is a substance that restores yang and dispels yin-cold. (It also functions as a tonic, specifically tonifying the Minister Fire of the Mingmen.)
[Preliminary Discussions] Yu Tun stated: Fuzi possesses a heroic and vigorous quality. It can guide qi-tonifying herbs through the twelve meridians to pursue and restore scattered Yuan Yang (Original Yang); it guides blood-tonifying herbs into... [text missing], removing... [text missing], benefiting yang... [text missing], spreading throughout... [text missing], waiting for... [text missing], which then... [text missing], the drug's barrier not... [text missing].
Aot An (Author's Note): Hot medicines are not limited to Fuzi; all ginger and cinnamon are similar. If both yang and qi are deficient, or if yin deficiency is more severe than yang deficiency, treating with hot medicines... [text missing]. Originally intended to tonify yang. I once saw a doctor treat a woman with yin deficiency. That doctor... [text missing] did not recover, and instead showed more signs of dryness and withering. This shows that although Renshen tonifies yang and has benefits, if used only with other yang-tonifying drugs, it has not been seen to be helpful. Reading... [text missing].
[Contraindications] Miao Xiyong in *Jingshu* states: All yang syndromes, fire syndromes, heat syndromes, yin deficiency with internal heat, and conditions with depleted blood are all contraindicated.
[Chuanwu]
Pungent in taste. Hot in nature. Toxic. It is the mother plant of Fuzi.
[Indications] Primarily treats wind-bi, blood-bi, hemiplegia, and various wind syndromes. Dispels cold sensations. Warms and nourishes the zang-fu organs. Removes hardness and fullness below the heart. Treats abdominal pain caused by cold invasion.
(From Li Gao/Jiegu) Dispels cold-dampness and unblocks the meridians. Disperses wind-pathogens. Breaks up various accumulated cold toxins. (From Li Gao) Tonifies insufficiency of the Mingmen. Treats liver wind deficiency. (From Wang Haogu)
[Meridian Tropism] Enters the Spleen and Mingmen meridians. It is a substance that assists yang and dispels yin. (Its function of circulating through the twelve meridians is similar to Fuzi but slightly milder.)
[Preliminary Discussions] Zong stated: To tonify deficiency-cold, one must use Fuzi; to dispel wind, one should mostly use Chuanwu. Roughly speaking, this is the case.
Shizhen (Li Shizhen) stated: Fuzi has a heavy and stagnant nature.
Aot An: Aconite root produced in Zhangming, Sichuan, is considered superior, hence the prefix "Chuan" (Sichuan) is added to distinguish it from Caowu (Wild Aconite). Fuzi is the lateral root attached to the main Aconite root, so it is also best when produced in Sichuan... [text missing].
Although summer... [text missing] again... [text missing] could it really be unusable? Otherwise, why do Zhang Zhongjing's Baibotong Decoction, Sini Decoction, and Zhenwu Decoction use it? Danxi (Zhu Zhenheng) emphasized nourishing yin, thus often unfairly disparaging yang-tonifying drugs. This is not a fair and balanced view.
