中风，北人多属寒，宜散寒，南人多属火、宜清火，而祛风、消痰则南北尽同。古方自仲景候氏黑散、
风引汤而外，则续命汤为主方。续命汤共有数首，不外驱风，其随症加减，皆有精义。从未有纯用温热滋
补，不放风寒痰火一毫外出，以致重病必死，轻病则使之不死不生。惟日服人参以破其家而恋其命，最可
伤也！又有稍变其说者用地黄饮子，以为得阴阳兼补之法，亦大谬也。此方乃治少阴气厥不至，舌喑足
痿，名曰痱症，乃纯虚无邪，有似中风，与风寒痰火之中风正相反，刘河间之书可考也。乃以此方治有邪
之中风，其害相等。余每年见中风之症，不下数十人，遵古治法，十愈八九，服温补药者，百无一愈，未甚
服补药者，尚可挽回；其不能全愈，或真不治者，不过十之一二耳！奈何一患此症，遂甘心永为废人，旁
人亦视为必不起之症，医者亦惟令多服重价之药，使之直得一死而可无遗憾，岂不怪哉！愿天下之中风
者，断勿以可愈之身，自投于必死之地也。
咳嗽由于风寒入肺，肺为娇脏，一味误投，即能受害。若用熟地、麦冬、萸肉、五味等滋腻酸敛之品
补住外邪，必至咯血、失音、喉癣、肛痈、喘急、寒热，近者半年，远者三年，无有不死。盖其服此等药之日，
即其绝命之日也。间有见几而停药者，或能多延岁月，我见以千计。故今之吐血而成痨者，大半皆由咳
嗽而误服补药所致也。或云五味子乃仲景治嗽必用之药，不知古方之用五味必合干姜，一散一收，以治寒
嗽之症，非治风火之嗽也，况加以熟地、麦冬，则受祸尤烈。又嗽药中多用桔梗，桔梗升提，甘桔汤中用
之以载甘草上行，治少阴之喉痛，与治嗽宜清降之法非宜，服者往往令人气逆痰升不得着枕。凡用药当深
知其性而屡试屡验，方可对病施治，无容冒昧也。
中风病，北方人多因寒邪所致，适宜用散寒法治疗；南方人多因火邪所致，适宜用清火法治疗。而祛风和消痰的治疗原则，南北两地则完全相同。古代方剂中，除了张仲景的候氏黑散、风引汤之外，主要以续命汤作为主方。续命汤共有多个版本，其核心作用不外乎驱除风邪，根据症状进行加减变化，其中都蕴含着精妙的医理。从未有过纯粹使用温热滋补药物，而不将风寒痰火等病邪排出体外的情况，这样做会导致重病者必然死亡，轻病者陷入不死不活的境地。只是每天服用的人参虽然耗尽了家财却只能勉强维持生命，这最让人伤心！又有稍微改变说法的人使用地黄饮子，认为这是阴阳双补的方法，这也是极大的错误。这个方子是治疗少阴经气机逆乱导致阳气不能下达，出现舌强不语、足部痿软的症状，称为痱症。这种病症属于纯虚无邪，看起来像中风，但与由风寒痰火引起的中风正好相反，可以参考刘河间的著作来考证。如果用这个方子治疗有实邪的中风，其危害是相同的。我每年见到的中风患者不下数十人，遵循古法治疗的，十人能痊愈八九个；服用温补药的，一百人中没有一个能痊愈；没有严重服用补药的，还可以挽回；那些不能完全痊愈，或者确实无法治愈的，不过只有十分之一二罢了！为什么一旦患上这种病，就甘心永远成为废人，旁人也都视为必死之症，医生也只让多服用昂贵的药物，使其直接死去以无遗憾，这难道不奇怪吗！希望天下的中风患者，千万不要把可以治愈的身体，自己投入到必死的境地中。
咳嗽是由于风寒侵入肺部，肺是娇嫩的脏器，一旦误用药物，就会受到伤害。如果使用熟地、麦冬、山茱萸、五味子等滋腻酸敛的药物来补益并留滞外邪，必然会导致咯血、失音、喉癣、肛周脓肿、气喘急促、恶寒发热等症状，短则半年，长则三年，没有不死亡的。可以说，服用这些药物的日子，就是他们的绝命之日。偶尔有见机行事停药的人，或许能多延长一些岁月，我见过的数以千计。所以现在吐血发展成肺痨的人，大半都是因为咳嗽时误服补药所导致的。有人说五味子是张仲景治疗咳嗽必用的药物，却不知道古方中使用五味子必定配合干姜，一散一收，用来治疗寒性咳嗽，而不是治疗风火性咳嗽，何况再加上熟地、麦冬，受到的祸害更加猛烈。另外，治咳药中多用桔梗，桔梗具有升提作用，在甘桔汤中使用它是为了载着甘草上行，治疗少阴经的咽喉疼痛，这与治疗咳嗽宜用清降的方法不相宜，服用后往往令人气逆痰升，无法安枕。凡是用药应当深入了解药性并且经过多次验证有效，才可以对症施治，不容许冒昧行事。
Apoplexy (Zhongfeng, Stroke) in the North is mostly caused by Cold pathogen, suitable for dispersing Cold; in the South, it is mostly caused by Fire pathogen, suitable for clearing Fire. However, dispelling Wind and eliminating Phlegm are consistent practices in both regions. Among ancient prescriptions, apart from Hou Shi Hei San (Black Powder of Hou Shi) and Feng Yin Tang (Wind-Driving Decoction) by Zhang Zhongjing, Xu Ming Tang (Life-Prolonging Decoction) serves as the main formula. There are several versions of Xu Ming Tang, all centered on driving out Wind, with modifications based on symptoms containing profound principles. It has never been appropriate to purely use warm and tonifying herbs without expelling Wind-Cold, Phlegm, or Fire pathogens, which leads to certain death in severe cases and a state of neither living nor dying in mild cases. Merely taking Ginseng Radix et Rhizoma (Renshen, 人参) daily depletes one's fortune while merely prolonging life, which is most lamentable! Some who slightly alter this approach use Di Huang Yin Zi (Rehmannia Infusion), claiming it achieves simultaneous tonification of Yin and Yang, which is also a major error. This formula treats Shaoyin syndrome characterized by Qi reversal failing to reach the extremities, manifesting as aphasia and lower limb flaccidity, known as Fei syndrome (Fei Zheng, 痱症). This condition is purely deficient without evil pathogens, resembling apoplexy but being exactly opposite to apoplexy caused by Wind-Cold, Phlegm, and Fire, as verifiable in Liu Hejian's works. Using this formula to treat apoplexy with excess pathogens causes equal harm. I see dozens of apoplexy patients annually; those treated according to ancient methods recover eight or nine out of ten. Those taking warm tonics have no cures among hundreds; those not heavily taking tonics can still be salvaged. The ones who do not fully recover or are truly incurable account for only one or two out of ten. Why, upon contracting this disease, do they resign themselves to becoming invalids forever? Bystanders view it as inevitably fatal, and physicians only advise taking expensive medicines until death occurs without regret. Is this not strange! I wish all apoplexy patients would never throw their curable bodies into inevitable death.
Cough results from Wind-Cold invading the Lung. The Lung is a delicate organ; misapplication of medication immediately causes harm. If one uses cloying and astringent tonics such as Prepared Rehmannia Root (Shu Dihuang, 熟地黄), Ophiopogon Tuber (Maidong, 麦冬), Cornus Fruit (Yurou, 山茱萸), and Schisandra Berry (Wuweizi, 五味子) to tonify and trap the external pathogen, it will inevitably lead to hemoptysis, aphonia, throat tinea, perianal abscess, dyspnea, aversion to cold, and fever. Death may occur within half a year or up to three years. Indeed, the day these medicines are taken is the day of their doom. Occasionally, those who stop medication upon seeing signs may extend their lives somewhat; I have seen thousands of such cases. Thus, most people today who develop consumption (Lao, 劳) due to hemoptysis do so because of mistakenly taking tonics during cough. Some claim that Schisandra Berry is an essential herb prescribed by Zhang Zhongjing for cough. They fail to know that in ancient formulas, Schisandra Berry is always combined with Dried Ginger (Ganjiang, 干姜), one dispersing and one astringing, to treat Cold-type cough, not Wind-Fire type cough. Furthermore, adding Prepared Rehmannia Root and Ophiopogon Tuber intensifies the disaster. Additionally, Platycodon Root (Jiegeng, 桔梗) is often used in cough remedies. Platycodon Root has an ascending property; in Gan Jie Tang (Licorice and Platycodon Decoction), it is used to carry Licorice Root (Gancao, 甘草) upward to treat Shaoyin throat pain, which is unsuitable for the descending method required for treating cough. Patients often experience rebellious Qi and rising Phlegm, making it impossible to rest their heads on pillows. Medications must be deeply understood in nature and repeatedly tested for efficacy before applying them to specific diseases, avoiding rash actions.
