凡看病要审元气虚实，实者不药自愈，虚者即当服药，灸关元穴以固性命。若以温平药，亦难取效，淹延
时日，渐成大病。（温平之药，近世所尚，旁人称其稳当，医士习于两岐，及至变成大病，惶急错投，误而又
误。总由识见不真，遂尔因循贻害。）
虚病多般，大略分为五种，有平气、微虚、甚虚、将
脱、已脱之别。平气者，邪气与元气相等，正可敌邪，只以温平药调理，缓缓而愈，如补中益气、小柴胡、八
物汤是也。微虚者，邪气旺，正气不能敌之，须服辛温散邪之药，当补助元气，使邪气易伏，宜荜澄茄散、全
真丹、来复丹、理中丸、姜附汤之类是也。甚虚者，元气大衰则成大病，须用辛热之药，浓味之剂，大助元阳，
不暇攻病也。《经》云∶形不足者，温之以气，精不足者，补之以味，即官桂、附子、鹿茸、河车之类是也。
将脱者，元气将脱也，尚有丝毫元气未尽，唯六脉尚有些小胃气，命若悬丝，生死立待，此际非寻常药饵所能
救，须灸气海，丹田、关元各三百壮，固其脾肾。夫脾为五脏之母，肾为一身之根。故伤寒必诊太溪、冲阳，
二脉者，即脾肾根本之脉也。此脉若存则人不死，故尚可灸，内服保元丹、独骸大丹、保命延寿丹，或可保其
性命。（单顾脾肾，乃先生学力大有根柢之论，盖肾为先天之原，脾为后天之本，资生资始，莫不由兹，故病
虽甚而二脉中有一脉未散，扶之尚可延生。）若已脱则真气已离，脉无胃气，虽灸千壮，亦无用矣。（此五种
证当于平时细心探讨，自然随机应变不致差讹。近世之医多尚寒凉，专行克伐，致使平气变虚，虚证变脱，及
至三焦失运，神气改常，出入道乖，升降机息，而犹执邪气未尽，火热未除之说，朝凉暮削，不死不休，良可悲痛！）
凡诊治疾病，必须审察元气的虚实状况。实证患者不需用药即可自愈；虚证患者则应当服药，并艾灸关元穴以固护性命。如果仅使用性质温和平和的药物，也难以取得疗效，只会拖延时日，逐渐演变成大病。（所谓温平之药，是近代医家所推崇的，旁人称赞其稳妥得当，医生们习惯于在两种治法之间摇摆不定，等到病情演变成大病时，便惊慌失措、错误投药，一误再误。这总归是因为见识不真切，从而因循守旧贻害病人。）
虚证种类繁多，大致分为五种：有平气、微虚、甚虚、将脱、已脱的区别。所谓“平气”，是指邪气与元气力量相等，正气足以抵御邪气，只需使用温和平和的药物进行调理，缓缓即可痊愈，如补中益气汤、小柴胡汤、八物汤等即是此类。所谓“微虚”，是指邪气旺盛，正气不能抵御，必须服用辛温发散邪气的药物，同时应当补助元气，使邪气容易伏降，适宜使用荜澄茄散、全真丹、来复丹、理中丸、姜附汤之类的方剂。所谓“甚虚”，是指元气大衰从而形成大病，必须使用辛热性质的药物和浓厚滋味的药剂，大力辅助元阳，此时已无暇顾及攻逐病邪了。《内经》说：“形体不足的，用气性温热的药物来温煦；精气不足的，用味厚的药物来滋补。”指的就是官桂、附子、鹿茸、紫河车这类药材。所谓“将脱”，是指元气即将耗脱，但尚有丝毫元气未尽，六脉之中还存有少许胃气，生命如同悬丝般微弱，生死只在顷刻之间，此时非寻常药物所能挽救，必须艾灸气海穴、丹田穴、关元穴各三百壮，以固护脾肾。因为脾是五脏的母亲，肾是一身的根本。所以治疗伤寒病必须诊察太溪穴和冲阳穴这两处的脉搏，这两处脉象就是脾肾根本的反映。如果这两处脉象尚存，人就不会死亡，因此还可以施灸，内服保元丹、独骸大丹、保命延寿丹，或许可以保全性命。（单从顾护脾肾立论，这是先生学术功底深厚的体现，盖因肾为先天之本原，脾为后天之根基，滋养生命起始与延续，无不由此出发，所以即使病情严重，只要脾肾两脉中有一脉未散，扶持它尚可延长生命。）所谓“已脱”，则是指真气已经离散，脉象中无胃气，即使艾灸千壮，也没有作用了。（这五种证候应当在平时细心探讨研究，自然能随机应变而不致出现差错。近代的医生多崇尚寒凉药物，专门施行克伐之法，致使原本平气的状态变为虚证，虚证进一步发展为脱证，等到三焦失去运化功能，神气改变常态，出入之道乖违，升降之机停止，却仍然执着于邪气未尽、火热未除的说法，早晨用凉药晚上用削伐药，不死不休，实在令人悲痛！）
In all cases of diagnosing and treating diseases, one must examine the deficiency or excess of Yuan Qi (Primordial Qi). In cases of Excess (Shi), the patient may recover without medication; in cases of Deficiency (Xu), medication should be administered, and moxibustion should be applied to Guanyuan (CV-4) to consolidate life and nature. If only mild and neutral medicines are used, efficacy is difficult to achieve, merely delaying time and gradually leading to severe illness. (Mild and neutral medicines are those favored by physicians in recent times; laypeople praise them as safe and steady. Physicians, accustomed to wavering between approaches, when faced with severe illness, become panicked and prescribe incorrectly, compounding errors. This stems entirely from a lack of true insight, leading to negligence and harm.)
Deficient conditions vary greatly but are roughly categorized into five types: Ping Qi (Balanced Qi), Wei Xu (Slight Deficiency), Shen Xu (Severe Deficiency), Jiang Tuo (Impending Collapse), and Yi Tuo (Complete Collapse). "Ping Qi" refers to a state where pathogenic factors and Yuan Qi are equal, allowing righteous Qi to effectively resist pathogens. Treatment involves regulating with mild and neutral medicines for a gradual recovery, such as Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction), Xiaochaihu Tang (Minor Bupleurum Decoction), and Bawu Tang (Eight Substances Decoction). "Wei Xu" indicates that pathogenic factors are vigorous while righteous Qi cannot resist them. One must administer acrid-warm medicines to disperse pathogens and simultaneously tonify Yuan Qi to facilitate the subjugation of pathogens. Suitable formulas include Bidengqie San (Cubeb Powder), Quanzhen Dan (Complete True Pill), Laifu Dan (Reviving Return Pill), Lizhong Wan (Regulate the Middle Pill), and Jiangfu Tang (Ginger and Aconite Decoction). "Shen Xu" occurs when Yuan Qi is severely depleted, resulting in serious illness. One must employ acrid-hot medicines and rich, thick preparations to vigorously assist Yuan Yang, leaving no time to attack the disease directly. The *Classic* states: "For insufficiency of form, warm with Qi; for insufficiency of essence, tonify with flavor." This refers to materials such as Guigui (Cinnamon Bark), Fuzi (Prepared Aconite Root), Lurong (Deer Antler Velvet), and Heche (Placenta Hominis). "Jiang Tuo" signifies that Yuan Qi is on the verge of collapse. Although a trace of Yuan Qi remains and the six pulses still show a slight amount of Stomach Qi, life hangs by a thread, with death imminent. At this juncture, ordinary medications cannot save the patient; one must apply moxibustion to Qihai (CV-6), Dantian (CV-8), and Guanyuan (CV-4), three hundred moxa cones each, to consolidate Spleen and Kidney. The Spleen is the mother of the five Zang organs, and the Kidney is the root of the entire body. Therefore, in treating Shanghan (Cold Damage), one must palpate the Taixi (KI-3) and Chongyang (ST-42) pulses, which reflect the roots of the Spleen and Kidney. If these pulses remain, the person will not die, so moxibustion is still viable. Internally, one may administer Baoyuan Dan (Protect Yuan Qi Pill), Duhanai Dadan (Great Pill of Solitary Skeleton), or Baoming Yanshou Dan (Protect Life and Extend Longevity Pill) to potentially preserve life. (Focusing solely on protecting the Spleen and Kidney reflects the profound foundation of the author's scholarship, as the Kidney is the origin of congenital constitution and the Spleen is the foundation of acquired constitution. All nourishment and initiation stem from here. Thus, even in severe illness, if one of the two pulses has not dispersed, supporting it can prolong life.) "Yi Tuo" means that True Qi has already departed, and the pulses lack Stomach Qi. Even if a thousand moxa cones are applied, it is of no use. (These five syndromes should be carefully studied in advance to ensure adaptive responses and avoid errors. Recent physicians often favor cold-cooling medicines and exclusively perform draining methods, causing balanced Qi to become deficient, and deficiency to progress to collapse. When the Triple Burner loses its transformative function, Spirit and Qi change their normal state, the pathways of entry and exit become discordant, and the mechanisms of ascending and descending cease, yet they persist in the theory that pathogenic factors are not fully eliminated and heat fire is not cleared. They administer cooling medicines in the morning and draining medicines in the evening, relentless until death, which is truly heartbreaking!)
