治验∶
一陈肃远，尝苦发晕，醒则日夜头眩。余往，候之脉，右虚左实，徐疾不常。余曰∶“此非放痧不可。”放腿弯上下
放十余针，紫黑血流如注，指上亦放二十余针。用宝花散、沉香阿魏丸清茶稍冷冻饮料之，付防风胜金汤加桃仁，红花稍冷
饮之，后遂不复患眩晕。
一姜渭滨内室，正月间，骤然发晕，一日三次，举家惶恐。余见其脉沉而微紧，令其婢为指上放痧三十余针。用救
苦丹加沉香末清茶稍冷冻饮料之，付荆芥银花汤加卜子、枳壳一剂而痊。
一梅君玉子三月间，吐蛔发晕，昏沉不醒，六脉俱伏，左右虎口脉青色，放指头痧一十八针，用细辛大黄丸清茶调
黑糖稍冷冻饮料之，渐苏，付蒲黄饮减姜黄加陈皮、乌药、红花微冷汤调黑糖饮之，乃愈。
一霍庭贤内室，四月间，壮热面赤，口渴唇焦，有以阳明胃经症药治之，遂发晕，终日不醒。余诊之脉，两寸弦细，
两关沉微，两尺左大右紧。曰∶“脉症不合，痧毒内攻也。”先用苏木散、砂仁汤微冷冻饮料之，令其老妇放指上痧二十余针，
血色墨黑，犹不醒，后令放乳边痧二针，乃苏。余症不减，用蒺藜散微温汤饮之，付桃仁红花汤加枳壳四剂，下尽恶毒
黑物而痊。
一盛思虞六月间饮酒，头汗发晕。脉寸关洪大无伦，两尺脉伏。阅痧筋，放十余针，皆紫黑毒血。付陈皮浓朴汤加
干葛，山楂、卜子微冷冻饮料之而醒，又用藿香汤加黄连、黄芩乃安。
眩晕有血晕、气晕、痰晕、火晕、湿晕、暑晕，还有因血虚引起的眩晕，因气虚引起的眩晕，因风邪侵袭引起的眩晕，因寒邪侵袭引起的眩晕，以及因过度劳累引起的眩晕。
如今又增加了痧晕（由痧毒引起的眩晕），古人没有治疗方法，古书也没有记载，我是如何知道的？大抵血晕的脉象是芤脉（浮大中空，如按葱管），气晕的脉象是沉脉（轻取不应，重按始得），痰晕的脉象是滑脉（往来流利，如盘走珠），火晕的脉象是数脉（一息五至以上），湿晕的脉象是濡脉（浮细而软），暑晕的脉象是虚脉（举之无力，按之空虚），血虚引起的眩晕脉象是涩脉（往来艰涩，如轻刀刮竹），气虚引起的眩晕脉象是微脉（极细极软，似有似无），风邪侵袭引起的眩晕脉象是浮缓脉（浮而弛缓），寒邪侵袭引起的眩晕脉象是弦紧脉（端直以长，如按琴弦，且紧张有力），过度劳累引起的眩晕脉象是右尺部浮洪脉（右手尺部脉位浅表且盛大）。这是各类眩晕脉象的大致规律。如果病症看似血晕但脉象反而短促，看似气晕但脉象反而浮起，看似痰晕但脉象反而涩滞，看似火晕但脉象反而迟缓，看似湿晕但脉象反而劲急，看似暑晕但脉象反而实大，看似血虚眩晕但脉象反而滑利，看似气虚眩晕但脉象反而宏大，看似风邪侵袭眩晕但脉象反而沉紧，看似寒邪侵袭眩晕但脉象反而微弱缓和，看似劳累眩晕但脉象反而细实，这些都是脉象与症状不相符合的情况。我经过多次验证，确信这些是痧晕，这种对痧晕的治疗方法是确凿可信的。
治疗验案：
有一位叫陈肃远的人，曾经苦于发作眩晕，清醒后日夜感到头晕目眩。我去为他诊脉，右手脉虚弱，左手脉实盛，脉搏徐疾无常。我说：“这非用放痧疗法不可。”在膝盖弯上下部位各放十余针，流出紫黑色的血液如同灌注一般，手指上也放二十余针。服用宝花散、沉香阿魏丸，用清茶稍微冷却后冰冻饮用；处方防风胜金汤加入桃仁、红花，稍冷后饮用，此后便不再患眩晕症。
姜渭滨的妻子，正月间突然发作眩晕，一天三次，全家惶恐不安。我见到她的脉象沉而微紧，让她的婢女在手指上放痧三十余针。服用救苦丹加入沉香末，用清茶稍微冷却后冰冻饮用；处方荆芥银花汤加入萝卜子、枳壳，一剂药后痊愈。
梅君玉的儿子，三月间吐出蛔虫并发作眩晕，昏沉不醒，六部脉象全部伏匿不见，左右虎口处脉络呈青色。在手指头放痧十八针，服用细辛大黄丸，用清茶调和黑糖稍微冷却后冰冻饮用，逐渐苏醒；处方蒲黄饮减去姜黄，加入陈皮、乌药、红花，用微冷的汤剂调黑糖饮用，于是痊愈。
霍庭贤的妻子，四月间高热面红，口渴唇焦，有人用治疗阳明胃经症状的药物来治她，结果导致发作眩晕，整天不醒。我为她诊脉，两寸脉弦细，两关脉沉微，两尺脉左侧大右侧紧。我说：“脉象与症状不符，这是痧毒内攻所致。”先用苏木散、砂仁汤稍微冷却后冰冻饮用，让家中的老妇人在手指上放痧二十余针，血色墨黑，病人仍不醒，后来又在乳房边缘放痧二针，才苏醒过来。其余症状未减，用蒺藜散用微温的汤剂饮用；处方桃仁红花汤加入枳壳，连服四剂，排出所有恶毒的黑物后痊愈。
盛思虞在六月间饮酒，头部出汗并发作眩晕。脉象寸部和关部洪大无比，两尺脉伏匿不见。观察痧筋，放十余针，流出的都是紫黑色的毒血。处方陈皮浓朴汤加入干葛、山楂、萝卜子，稍微冷却后冰冻饮用而苏醒，后又用藿香汤加入黄连、黄芩才安定下来。
Vertigo may be caused by blood stasis (Blood Vertigo), Qi stagnation (Qi Vertigo), phlegm (Phlegm Vertigo), fire (Fire Vertigo), dampness (Dampness Vertigo), or summerheat (Summerheat Vertigo). It can also arise from blood deficiency, Qi deficiency, invasion of wind pathogens, invasion of cold pathogens, or overexertion.
Now, adding "Sha Vertigo" (vertigo caused by Sha toxin) to this list: ancient physicians had no treatment for it, and ancient texts did not discuss it. How do I know? Generally, Blood Vertigo presents with a Kou pulse (Kou Mai, hollow like a scallion stem); Qi Vertigo presents with a Chen pulse (Chen Mai, deep); Phlegm Vertigo presents with a Hua pulse (Hua Mai, slippery); Fire Vertigo presents with a Shu pulse (Shu Mai, rapid); Dampness Vertigo presents with a Ru pulse (Ru Mai, floating and fine); Summerheat Vertigo presents with a Xu pulse (Xu Mai, empty); Vertigo due to blood deficiency presents with a Se pulse (Se Mai, choppy); Vertigo due to Qi deficiency presents with a Wei pulse (Wei Mai, minute); Vertigo due to wind invasion presents with a Fu-Huan pulse (Fu-Huan Mai, floating and moderate); Vertigo due to cold invasion presents with a Xian-Jin pulse (Xian-Jin Mai, string-taut and tight); Vertigo due to overexertion presents with a Fu-Hong pulse at the Right Chi position (Right Cun-Guan-Chi pulse positions correspond to Lung/Heart/Spleen/Stomach/Liver/Kidney; Chi refers to the distal position on the wrist). This is a general overview of vertigo pulses. However, if the symptoms resemble Blood Vertigo but the pulse is instead Short (Duan); resembles Qi Vertigo but the pulse is Floating (Fu); resembles Phlegm Vertigo but the pulse is Choppy (Se); resembles Fire Vertigo but the pulse is Slow (Chi); resembles Dampness Vertigo but the pulse is Tense/Firm (Jin); resembles Summerheat Vertigo but the pulse is Excess (Shi); resembles blood-deficiency vertigo but the pulse is Slippery (Hua); resembles Qi-deficiency vertigo but the pulse is Large (Da); resembles wind-invasion vertigo but the pulse is Deep-Tight (Chen-Jin); resembles cold-invasion vertigo but the pulse is Minute-Slow (Wei-Huan); resembles exertion vertigo but the pulse is Fine-Excess (Xi-Shi)—these are all cases where the pulse and symptoms do not match. Having verified this through experience, I am confident these are Sha Vertigo cases. Thus, the treatment for Sha Vertigo is reliable.
Case Records:
1. Mr. Chen Suyuan suffered from recurrent vertigo, experiencing dizziness day and night upon waking. Upon examination, his Right pulse was Deficient while the Left pulse was Excess, with irregular speed. I stated, "This requires Sha release therapy." I performed cupping/bleeding with over ten needles above and below the popliteal fossa, releasing dark purple-black blood profusely. Over twenty needles were used on the fingers. He took Baohua San (Precious Flower Powder) and Chenxiang Awai Wan (Agarwood and Asafoetida Pill), administered with clear tea slightly cooled and chilled. A prescription of Fangfeng Shengjin Tang (Saposhnikovia Decoction to Win Gold) added with Taoren (Peach Kernel) and Honghua (Safflower) was given, consumed slightly cool. Thereafter, he never suffered from vertigo again.
2. The wife of Jiang Weibin suddenly developed vertigo in the first lunar month, occurring three times a day, causing family panic. Her pulse was Deep and slightly Tight. I instructed her maid to perform Sha release on the fingers with over thirty needles. She took Jiuku Dan (Salvation Pill) mixed with Agarwood powder, administered with clear tea slightly cooled and chilled. A prescription of Jingjie Yinhua Tang (Schizonepeta and Honeysuckle Decoction) added with Boluozi (Radish Seed) and Zhike (Aurantium Fructus) cured her in one dose.
3. The son of Mei Junyu vomited roundworms in the third lunar month and developed vertigo, falling into a coma. All six pulse positions were Hidden (Fu). The Sha veins at the Tiger's Mouth (He Gu area) were blue-green. Eighteen needles were used to release Sha from the fingertips. He took Xixin Dahuang Wan (Asarum and Rhubarb Pill), mixed with clear tea and brown sugar, administered slightly cooled and chilled. He gradually regained consciousness. A prescription of Puhuang Yin (Polygonum Multiflorum Drink) with Jianghuang (Turmeric) removed, added with Chenpi (Tangerine Peel), Wuyao (Lindera Root), and Honghua (Safflower), was taken with brown sugar in a slightly cool decoction, leading to recovery.
4. The wife of Huo Tingxian presented with high fever, red face, thirst, and dry lips in the fourth lunar month. Treatment with herbs for Yangming Stomach Channel symptoms induced vertigo, leaving her unconscious all day. Her pulse was String-Taut and Fine at both Cun positions, Deep and Minute at both Guan positions, and Large on the Left Chi and Tight on the Right Chi. I said, "The pulse and symptoms do not match; this is Sha toxin attacking internally." First, Sumu San (Sappan Wood Powder) and Sharen Tang (Amomum Decoction) were given, slightly cooled and chilled. An elderly woman released Sha from the fingers with over twenty needles; the blood was ink-black, yet she remained unconscious. Then, two needles were used to release Sha near the breast, after which she revived. Other symptoms persisted. Jili San (Tribulus Powder) was given in a slightly warm decoction. Tao Ren Hong Hua Tang (Peach Kernel and Safflower Decoction) added with Zhike was prescribed for four doses. After expelling all foul black toxic matter, she recovered.
5. Sheng Siyu drank alcohol in the sixth lunar month, sweating on the head and developing vertigo. His Cun and Guan pulses were excessively Surging and Large, while both Chi pulses were Hidden. Observing the Sha veins, over ten needles were used, releasing dark purple-black toxic blood. A prescription of Chenpi Nongbo Tang (Tangerine Peel and Magnolia Bark Decoction) added with Gange (Kudzu Root), Shanzha (Hawthorn Fruit), and Boluozi (Radish Seed) was given, slightly cooled and chilled, restoring consciousness. Subsequently, Huoxiang Tang (Patchouli Decoction) added with Huanglian (Coptis Rhizome) and Huangqin (Scutellaria Root) stabilized him.
