夫君子生于斯世，不屑为天下无所用之人，则必求为天下所必需之人，故君子不为良相，则为良医。盖良相济世，
良医济生，其所以行我心之不忍者，事有相符，而道有相类也。余于伤寒、痘疹、惊风、虐、痢与夫胎前产后等症，俱

非若他症之可以迁延时日，姑且慢为调治也。迩来四方疫气时行，即今丑寅年间，痧因而发，乡村城市之中，俱见有此
等症。或为暗痧，或为闷痧，或为痧痛，或为落弓痧、噤口痧、扑鹅痧、角弓痧、盘肠痧，或又因伤寒、虐、痢与夫胎

用药以济之，然后三法兼备，救生而生全，庶乎斯人之得有其命也。其如世有刮痧放痧之人，仅有刮放之能而已，余俱
非所长也。故痧有放之不出，刮之不起，便云凶，而且放痧数次不愈，刮痧数次不痊，便听命于天而垂毙者，往往皆然。
若夫业医诸友，责在救人，推其心，岂非当世之所谓君子与。然其间或有云诸书不载痧名，满洲因而谓非药可疗，不知
载籍之内，原有云绞肠痧者、有云干霍乱者、有云青筋者、有云白虎症者、有云中恶者，此皆痧之见于诸书，但略而不

痧有为真心痛，亦朝发夕死，夕发旦死，寄于真心痛之例。此二症者，虽属不治，若知其原于痧者而疗之，亦可挽回。
况痧有为头面肿胀，一似大头瘟；痧有为咽喉锁闷，一似急喉风；痧有为眩晕昏闷，少顷云殂，一似中风、中暑；痧有

为集，仍不敢秘，以公诸世。庶几其有以行我心之不忍，而幸不为斯世无所用之人欤。
君子生于这个世间，不屑于成为对天下毫无用处的人，因此必定追求成为天下不可或缺的人。所以，君子如果不能做优秀的宰相，就会去做优秀的医生。大概优秀的宰相能救助世人，优秀的医生能拯救生命，他们践行内心不忍见他人受苦的道义，在行事上相互契合，在道理上也极为相似。
我对于伤寒、痘疹、惊风（小儿惊厥）、疟疾、痢疾以及胎前产后等病症，都曾潜心研究，这里暂且不详细赘述。唯独这“痧”这一病症，病情缓和的或许还可以拖延；但病情急重的，性命就在顷刻之间。对于患病家属来说，必须诚心诚意地请求救治；对于医生来说，必须紧急前往援助。这不像其他病症那样可以迁延时日，姑且慢慢调理治疗。
近来四方疫气流行，就在丑寅年间（指清康熙四十一年至四十二年，即1702-1703年左右），因痧气而引发的疾病爆发，无论是乡村还是城市，都出现了这类病症。有的表现为暗痧，有的表现为闷痧，有的表现为痧痛，有的表现为落弓痧、噤口痧、扑鹅痧、角弓痧、盘肠痧，或者又因为伤寒、疟疾、痢疾以及胎前产后等病症，导致痧症并发，甚至全家遭殃，邻里相传，令人极度悲痛。我曾遇到这类病症，进行临危急救，数量多得难以计算。
其治疗的大略方法，有三法：如果痧邪在肌肤表层，通过刮痧即可痊愈；如果痧邪在血肉深层，通过放血疗法即可痊愈，这两种情况都属于痧邪较浅的，即使病情严重也相对较轻。至于痧邪深重者，胀塞肠胃，壅阻经络，直接攻击少阴心君（心脏），不是命悬一线，就是危在旦夕，扶不起来，叫不应声，此时即使想刮痧或放血，也因为痧胀到了极点，难以实施刮放操作了。唉，病人濒临死亡，谁不伤心？痧症到了这种地步，确实非药物不能救醒，非药物不能起死回生。那么在刮痧和放血之外，必须用药来辅助，这样三法兼备，才能救生并保全生命，这些人才能得以存活。
然而世上有些只会刮痧放痧的人，仅有刮放的技能而已，我并不擅长这些。所以遇到痧症放不出血、刮不起痧的，就说是凶险；而且放痧多次不愈，刮痧多次不痊，便听天由任其垂死的人，往往都是这种情况。如果是从事医学的朋友，责任在于救人，推究他们的用心，难道不是当世所谓的君子吗？
然而其中有的人说各种医书没有记载“痧”这个名字，满洲人因此认为这不是药物可以治疗的。却不知道在典籍中，原来有称为“绞肠痧”的，有称为“干霍乱”的，有称为“青筋”的，有称为“白虎症”的，有称为“中恶”的，这些都是痧症见于诸书的记载，只是简略而不详细，没有专门的专家论述。然而并没有看到说应该断绝药物治疗的，这是彰明较著、显而易见的。
况且痧症有的表现为真头痛，早晨发作晚上死亡，晚上发作早上死亡，附属于头痛的条目下；痧症有的表现为真心痛，也是朝发夕死、夕发旦死，附属于真心痛的例子下。这两种病症，虽然属于不治之症，但如果知道它们源于痧症并进行治疗，也可以挽回生机。
况且痧症有的表现为头面肿胀，很像大头瘟（流行性腮腺炎或颜面丹毒等）；痧症有的表现为咽喉锁闷，很像急喉风（急性喉梗阻）；痧症有的表现为眩晕昏闷，一会儿就死亡，很像中风、中暑；痧症有的表现为失语沉迷，身体沉重疼痛，很像惊魂落魄。这些情况都在危急之中，如果不及时刮痧放血，不用药物将用什么来救治呢？
更何况痧症有的表现为头痛、寒热，类似于伤寒；咳嗽烦闷，类似于伤风；以及因为疟疾而兼夹痧症，因为痧症而转化为疟疾；或者又因为痢疾而引发痧症，因为痧症而产生痢疾。痧症表现百出，传变多端，更不仅仅是上述这些情况。诸如鼻出血、吐血、便血，由痧症引起的也有。更有大肿、大毒、流火、流痰，由此产生的也有。或者又有胎前、产后、气郁、食郁、血郁、火郁，而兼发痧症的。或者又有痧症导致手肿、足肿、手痛、足痛，牵连全身不能转动的。或者又有痧症导致胸胁肚腹结成痧块，很像痞闷，很像结胸证的。或者又有痧症导致吐蛔虫、泻蛔虫、食积、积滞、血瘀的。或者又有痧症导致心痛、胁痛、腹痛、腰痛、盘肠痛、吊痛、遍身疼痛，几乎无法生存的。
况且痧症常常有内伤杂病导致的，即将濒死的情况，男子患此，类似蓄血证，但血分的治法不同；女子患此，类似倒经，但气分的治法也不同。
总的来说，痧症作为疾病，种种不一，难以一一列举，我特别指出其大略，并阐明最关键之处：必须辨别脉象的真假，确认症状的确切，然后投药必然得当，用药不会虚误。如果痧在肌肤，应当刮痧就刮痧；痧在血肉，应当放血就放血；痧在肠胃、经络与肝、肾、脾三阴经，应当用药就用药。如果痧气肆行，不拘泥于表里，传变遍及周身，应当三法兼用。务必在病人将危时挽救，在将死时使其复生。
我治疗这类病症，随处救人，确有奇效。私下担心前人不论述，难以启发后辈贤才，因此撰写成集，仍不敢保密，以此公之于世。希望这能践行我不忍之心，庆幸自己不为这个世间无所用之人吧。
A gentleman born in this world, unwilling to be a person of no use to the world, must strive to become an indispensable person. Therefore, if a gentleman cannot serve as an excellent prime minister (Liangxiang), he will become an excellent physician (Liangyi). Generally speaking, an excellent prime minister saves the world, while an excellent physician saves lives; their actions align with their inner compassion for others' suffering, and their principles are similar.
I have devoted myself to studying diseases such as Shanghan (Cold Damage), Douzhen (Smallpox/Chickenpox), Jingfeng (Pediatric Convulsions), Nue (Malaria), Li (Dysentery), and conditions before and after childbirth, which I shall not elaborate on here. However, regarding the disease known as "Sha" (Sand/Plague toxin), mild cases may allow for delay, but acute cases hang by a thread. For patients' families, sincere pleas for help are essential; for physicians, urgent assistance is required. This differs from other ailments that can be managed slowly over time.
Recently, epidemic qi has circulated widely. During the Chou-Yin years (approx. 1702-1703 AD), Sha outbreaks occurred in both rural and urban areas. Manifestations include Ansha (Hidden Sha), Mensha (Stifling Sha), Shatong (Sha Pain), Luogongsha, Jinkousha, Pu'eshasha, Gonggongsha, Panchangsha, or concurrent Sha with Shanghan, Malaria, Dysentery, or postpartum conditions. Entire households may suffer, spreading among neighbors, causing deep sorrow. I have encountered many such critical cases requiring emergency rescue.
The general treatment methods involve three approaches: If Sha is in the skin and muscles, scraping (Gua Sha) cures it; if Sha is in the flesh and blood, bloodletting (Fang Sha) cures it. These two represent superficial Sha, which remains manageable even if severe. However, deep and severe Sha obstructs the intestines and stomach, blocks meridians, and directly attacks the Heart (Shao Yin Zong Zhu). Such patients are either critically ill or dying within days. They cannot be supported or roused. At this extreme stage, scraping or bloodletting becomes difficult. Alas, seeing patients near death is heartbreaking. When Sha reaches this point, only medicine can revive them. Thus, beyond scraping and bloodletting, medicinal treatment is necessary. Combining all three methods ensures survival.
Some practitioners only know scraping and bloodletting. If these fail, they declare the case fatal and abandon the patient. This is common. Physicians, however, bear the responsibility to save lives and act as gentlemen. Some claim medical texts do not record "Sha," suggesting it is untreatable by medicine. Yet, ancient texts mention "Jiaochangsha" (Intestinal Twisting Sha), "Gan Huoluan" (Dry Cholera), "Qingjin" (Blue Veins), "Baihuzheng" (White Tiger Syndrome), and "Zhong'e" (Sudden Evil Strike). These are early records of Sha, though brief and lacking specialized study. No text explicitly states that Sha should not be treated with medicine.
Furthermore, Sha can manifest as "True Headache" (Zhen Tou Tong), fatal within hours, recorded under headache categories; or "True Heart Pain" (Zhen Xintong), also rapidly fatal, recorded under heart pain examples. Though often considered incurable, recognizing Sha as the cause allows for potential recovery.
Sha may present as facial swelling resembling Datouwen (Big Head Plague); throat obstruction resembling Ji Houfeng (Acute Throat Wind); dizziness and coma resembling Zhongfeng (Stroke) or Zhongshu (Heat Stroke); or aphasia and lethargy resembling lost soul/spirit. In these critical states, without timely scraping/bloodletting, medicine is the only hope.
Sha symptoms mimic many diseases: headache and chills resemble Shanghan; cough and irritability resemble Shangfeng (Wind Cold); malaria may coexist with or transform into Sha; dysentery may trigger Sha. Sha presents in myriad ways: epistaxis, hematemesis, hematochezia; massive swelling, toxicity, flowing fire, flowing phlegm; pre/post-natal complications; Qi, Food, Blood, or Fire stagnation triggering Sha; limb swelling/pain; abdominal masses resembling Pi (Glomus) or Jiexiong (Chest Binding); vomiting/passing roundworms; chest, hypochondriac, abdominal, lower back, or generalized pain. In men, it may resemble Xuxue (Blood Stasis) but requires different blood-level treatment; in women, it may resemble Daojing (Retrograde Menstruation) but requires different Qi-level treatment.
Sha is diverse and complex. The key lies in distinguishing true vs. false pulses and accurately identifying symptoms before prescribing. Treat Sha in skin/muscles with scraping; in flesh/blood with bloodletting; in intestines, meridians, and Liver/Kidney/Spleen Yin channels with herbs. If Sha spreads extensively regardless of exterior/interior levels, combine all three methods. My goal is to save the critically ill and revive the dying. My treatments have proven effective. I publish this collection to enlighten future generations, fulfilling my duty to humanity and ensuring I am not useless to the world.
