儒者王清之跌腰作痛，用定痛等药不愈，气血日衰，面目黧色。余曰∶腰为肾之府，虽
曰闪伤，实肾经虚弱所致。遂用杜仲、补骨脂、五味、山茱、苁蓉、山药，空心服；又以六
君、当归、白术、神曲各二钱，食远服。不月而瘥。
一二三岁儿闪腰作痛，服流气等药半载不愈。余曰∶此禀肾气不足，不治之症也。后果
殁。
一妇人伤指，手臂俱肿，微呕少食。彼以为毒瓦斯内攻，诊其脉沉细，此痛伤胃气所致也
，遂刺出脓碗许。先以六君、藿香、当归而食进，继以八珍、黄 、白芷、桔梗，月余而疮
愈。

一男子修伤足指，色黑不痛而欲脱。余曰∶此因阳气虚，不能运达于患处也，急去之，
速服补剂以壮元气，否则死肉延足，必不救矣。不信。果黑烂上胫而死。大抵手足气血罕到
之地，或生疮、或伤损，若戕其元气，邪气愈盛，溃烂延上必死，不溃而色黯者亦死。若骨
断筋皮尚连者，急剪去之。
一女年数岁，严寒上京，两足受冻不仁，用汤泡渍，至春十指俱烂，牵连末落。余用托
里之剂，助其阳气，自溃脱，得保其生。此因寒邪遏绝，运气不至，又加热汤泡渍，故死而
不痛也。余尝见人之严寒而出，冻伤其耳目不知痛，若以手触之，其耳即落，当以暖暖处
良
久，或热手熨之无恙，若以火烘汤泡，其耳即死，至春必溃脱落矣。北方寒气损人若此，可
不察之！

读书人王清之腰部扭伤导致疼痛，使用定痛等药物治疗后病情未愈，气血日渐衰弱，面色发黑。我说：腰是肾的外府，虽然说是闪挫损伤，实际上是肾经虚弱所致。于是用杜仲、补骨脂、五味子、山茱萸、肉苁蓉、山药，空腹服用；又以六君子汤、当归、白术、神曲各二钱，饭后较远的时间服用。不到一个月就好了。
一两三岁的幼儿闪伤腰部导致疼痛，服用流气等药物半年未愈。我说：这是禀受肾气不足，属于难治之症。后来果然去世了。
一位妇人手指受伤，手臂全部肿胀，轻微呕吐，进食很少。她认为是毒气内攻，诊察她的脉象沉细，这是疼痛损伤了胃气所致。于是刺破排出脓液约一碗。先用六君子汤、藿香、当归治疗，使饮食增加；继而又用八珍汤、黄芪、白芷、桔梗治疗，一个多月后疮口愈合。

一名男子修剪脚趾时受伤，脚趾颜色发黑，不疼痛且快要脱落。我说：这是因为阳气虚弱，不能运达至患处。急忙去除坏死的组织，迅速服用补益剂以壮大元气，否则坏死肌肉蔓延至小腿，必定无法救治。他不相信。结果黑色腐烂向上蔓延至小腿而死。大抵手足是气血很少到达的地方，如果生疮或受伤，若戕害其元气，邪气就会更加旺盛，溃烂向上蔓延必然死亡，如果不溃烂但颜色暗黑的也会死亡。如果骨头断裂而筋皮还连接着的，急忙剪去坏死部分。
一个几岁的女孩，在严寒时节前往京城，双脚受冻失去知觉，用热水浸泡，到了春天十个手指全部腐烂，牵连到末端脱落。我使用托里透脓的药剂，帮助其阳气，自然溃烂脱落，得以保全生命。这是因为寒邪遏制断绝，运气不能到达，又加上用热汤浸泡，所以虽死而不痛。我曾经见过有人在严寒中外出，冻伤了耳朵和眼睛却不知道疼痛，如果用手触摸，耳朵就会掉落，应当在温暖的地方放置很久，或者用热手熨烫才能无恙，如果用火烘烤或用汤浸泡，耳朵就会坏死，到了春天必然溃烂脱落。北方的寒气损害人体如此严重，能不仔细考察吗！
(Second Case)
A scholar, Wang Qingzhi, suffered from lower back pain due to a sprain. After using pain-relieving medications without improvement, his qi and blood declined daily, and his complexion turned dark. I stated: "The waist is the mansion of the Kidney. Although it is termed a sprain injury, it is actually caused by weakness in the Kidney channel." Therefore, I prescribed Eucommiae Cortex (Duzhong), Psoraleae Fructus (Buguzhi), Schisandrae Fructus (Wuweizi), Corni Fructus (Shanzhuyu), Cynomorii Herba (Rongrong), and Dioscoreae Rhizoma (Shanyao) for consumption on an empty stomach; and Six Gentlemen Decoction (Liujunzi Tang) combined with Angelicae Sinensis Radix (Danggui), Atractylodis Macrocephalae Rhizoma (Baizhu), and Massae Fermentatae Medicinalis (Shenqu), each at two qian, taken well after meals. He recovered within less than a month.
An infant aged one to three years suffered from lower back pain due to a sprain. After taking Qi-circulating medications for half a year without improvement, I stated: "This is due to insufficient congenital Kidney qi; it is a difficult-to-treat condition." He subsequently died.
A woman injured her finger, resulting in swelling of the entire arm, slight vomiting, and poor appetite. She believed it was internal attack by toxic vapors. Upon palpation, her pulse was deep and fine. I diagnosed this as damage to Stomach qi caused by pain. I punctured the area to drain approximately one bowl of pus. Initially, I treated her with Six Gentlemen Decoction (Liujunzi Tang), Agastaches Herba (Huoxiang), and Angelicae Sinensis Radix (Danggui), which improved her appetite. Subsequently, I administered Eight Treasures Decoction (Bazhen Tang) with Astragali Radix (Huangqi), Angelicae Dahuricae Radix (Baizhi), and Platycodonis Radix (Jiegeng). The wound healed after more than a month.
(Second Case)
A man injured his toe while trimming it. The toe turned black, was painless, and appeared ready to fall off. I stated: "This is due to deficiency of Yang qi, which fails to circulate to the affected area." I urgently removed the necrotic tissue and instructed him to rapidly take tonifying agents to strengthen his Yuan qi. Otherwise, the dead flesh would spread up the leg, and he would be incurable. He did not believe me. Indeed, the black rot spread to the calf, and he died. Generally, the hands and feet are areas where qi and blood rarely reach. If sores or injuries occur there, and if the Yuan qi is damaged, the pathogenic qi will become even stronger. Ulceration spreading upward leads to death; non-ulcerated but darkened lesions also lead to death. If bones are broken but tendons and skin remain connected, the necrotic parts should be urgently excised.
A girl of several years old traveled to the capital during severe cold. Her feet became numb due to frostbite. She soaked them in hot water. By spring, all ten fingers had rotted and eventually fell off. I used formulas to support the interior and promote suppuration, assisting her Yang qi. The necrotic tissue naturally sloughed off, allowing her to survive. This occurred because Cold pathogen obstructed and cut off circulation, preventing qi and blood from reaching the extremities, compounded by soaking in hot water, causing tissue death without pain. I have observed people who go out in severe cold and suffer frostbite to ears and eyes without feeling pain. If touched by hand, the ear may detach. They should be kept in a warm place for a long time or warmed with hot hands to recover safely. However, if exposed to fire or soaked in hot water, the tissue dies and will ulcerate and fall off by spring. Northern Cold damages the human body in such ways; one must examine this carefully!
