赤白游风属脾肺气虚，腠理不密，风热相搏；或寒闭腠理，内热拂郁；或阴虚火动，外
邪所
山栀、丹皮。风热相搏，用荆防败毒散。内热、外寒，用加味羌活散。胃气虚弱，用补中益
气汤加羌活、防风及消风散。血虚，用加味逍遥散。阴虚，逍遥散、六味丸。若肝肾虚热，
用六味丸，则火自息，风自定，痒自止。若用祛风辛热之剂，则肝血愈燥，风火愈炽，元气
愈虚。腠理不闭，风客内淫，肾气受伤，相火翕合，血随火化，反为难治矣。

赤白游风属于脾肺之气虚弱，腠理（皮肤纹理及汗孔）不致密，导致风热相互搏结；或者是寒邪闭塞腠理，体内热气拂郁不畅；或者是阴虚导致虚火妄动，遭受外邪侵袭。若属风热相搏，使用荆防败毒散。若属内热兼外寒，使用加味羌活散。若属胃气虚弱，使用补中益气汤加入羌活、防风以及消风散。若属血虚，使用加味逍遥散。若属阴虚，使用逍遥散和六味丸。如果是肝肾虚热，使用六味丸，则虚火自然平息，风邪自然安定，瘙痒自然停止。如果使用祛风辛热的药物，则肝血更加干燥，风火更加炽盛，元气更加虚弱。腠理不能闭合，风邪客居体内并深入淫溢，肾气受到损伤，相火翕合（指相火妄动或闭郁），血液随着火势而化燥，反而变得难以治疗。
治验记录：
有一个男子在秋季发作疙瘩，这是元气虚弱而遭受外邪侵袭所致。先用九味羌活汤两剂，又用补中益气汤加入羌活而痊愈。后来不慎起居作息，出现盗汗、傍晚发热、口干、唾痰、身体疲倦、懒于说话的症状，使用补中益气汤和加减八味丸而痊愈。
有一个妇人全身像丹毒一样红肿，抓破后脓水淋漓，伴有热渴、头晕，症状在傍晚加重。使用加味逍遥散而痊愈。
有一个妇人患赤白游风，傍晚发热且瘙痒剧烈，我用清肝养血的药物治疗。她不相信我的诊断，反而服用大麻风药，导致手臂疼痛且筋脉拘挛；后来又服用化痰顺气的药物，导致四肢痿弱无力而死。
有一个妇人患前症（赤白游风），多次使用风药煎汤泡洗，导致腹胀而死。
有一个女子面部赤晕如霞，感到瘙痒发热，使用加味小柴胡汤加入生地、连翘、丹皮而痊愈。
疥疮属于脾经湿毒积热，或者是肝经血热、风热，或者是肾经阴虚发热。如果身体疲倦、食欲减少，属于脾经湿热，使用除湿胃苓散。如果搔痒作痛，属于风热，使用当归饮子。如果便秘作痛，属于热毒，使用升麻和气饮。如果热渴且大便通畅，属于脾肺虚热，使用竹叶石膏汤。如果体内发热、傍晚发热，或者时而恶寒时而发热，属于肝经血虚风热，使用加味逍遥散和六味丸。如果身体疲倦、进食少，或者盗汗、睡眠少，属于脾气郁结，使用加味归脾汤、逍遥散和地黄丸。如果出现发热盗汗，或者吐痰、口干的症状，属于肾经虚热，使用六味丸的药料煎服。
治验记录：
稽勋官李龙冈，遍身患有此病，腿足部位尤为严重。傍晚症状加重，口干作渴，小便频繁且色赤，这是肾经虚热，使用补中益气汤和六味丸而痊愈。
有一个读书人善于打喷嚏且患瘙痒，我认为这是内有湿热，腠理不致密，外邪搏击所致，给予补中益气汤加入白芷、川芎治疗。
有一个读书人患病在臂脚，傍晚时或痒或胀，形体倦怠，自己服用败毒散，导致痛处发肿，小便赤涩，这是肺肾阴虚。我使用补中益气汤加入五味子、麦门冬而痊愈。
有一个读书人患此病，误用攻伐的药物，导致元气虚弱而不能痊愈。使用补中益气汤加入茯苓，其疮顿然痊愈。后来又因调养失宜，傍晚症状加重，使用八珍汤，加入五味子、麦门冬，五十多剂后痊愈。

有一个男子在时疫痊愈后所患此病，如果用前面的药物，通过补养而痊愈。有同样患病的人，使用砭法放血而死。这是因为阴虚血热，肤色黑且作痒。为何反而伤害阴血呢？
有一个妇人久治不愈，饮食少、身体疲倦，这是肝脾亏损导致的虚热，先用补中益气汤，加入川芎、炒山栀，使元气逐渐恢复，再用四物汤合小柴胡汤。热退后，却改用逍遥散，以补脾胃，生阴血。也有出现寒热如疟疾症状的，也用前面的药物治疗。
Chibo Youfeng (Red and White Wandering Wind) belongs to the deficiency of Spleen and Lung Qi, with loose Cou Li (skin texture and pores), leading to the struggle between Wind and Heat; or it is caused by Cold closing the Cou Li, causing internal Heat to be stifled and depressed; or it results from Yin deficiency triggering Fire movement, making one susceptible to external pathogens. If due to Wind-Heat struggling, use Jingfang Baidu San (Atractylodes and Saposhnikovia Powder to Overcome Toxins). If due to internal Heat combined with external Cold, use Jia Wei Qiang Huo San (Modified Notopterygium Decoction). If due to Stomach Qi weakness, use Buzhong Yiqi Tang (Decoction for Reinforcing the Middle and Augmenting Qi) added with Qiang Huo and Fang Feng, along with Xiaofeng San (Wind-Expelling Powder). If due to Blood deficiency, use Jia Wei Xiaoyao San (Modified Free and Easy Wanderer Powder). If due to Yin deficiency, use Xiaoyao San and Liuwei Wan (Six-Ingredient Rehmannia Pill). If it is Liver-Kidney deficient Heat, using Liuwei Wan will cause the Fire to subside naturally, the Wind to settle, and the itching to stop. If wind-expelling acrid-hot agents are used, Liver Blood will become drier, Wind-Fire will blaze more fiercely, and Yuan Qi (Original Qi) will become more deficient. If the Cou Li fails to close, Wind lodges internally and invades deeply, damaging Kidney Qi, causing Xiang Huo (Ministerial Fire) to flare up, Blood transforming with the Fire, making it difficult to treat.
Case Records:
A man developed nodules in autumn; this was due to deficient Yuan Qi invaded by external pathogens. Initially, he took Jiwei Qianghuo Tang (Nine-Ingredient Notopterygium Decoction) for two doses, then recovered after taking Buzhong Yiqi Tang added with Qiang Huo. Later, due to improper daily routine, he experienced night sweats, afternoon fever, dry mouth, expectoration of phlegm, body fatigue, and reluctance to speak. He recovered using Buzhong Yiqi Tang and Jiaban Bawei Wan (Modified Eight-Ingredient Pill).
A woman had a body resembling Dansu (Erysipelas), with oozing pus when scratched, accompanied by heat, thirst, dizziness, and worsening symptoms in the afternoon. She recovered using Jia Wei Xiaoyao San.
A woman suffered from Chibo Youfeng, with severe evening fever and intense itching. I prescribed herbs to clear the Liver and nourish Blood. Disbelieving my diagnosis, she took medicines for Leprosy (Dama Feng Yao), resulting in arm pain and tendon contraction. Subsequently, she took phlegm-resolving and Qi-regulating agents, leading to flaccidity of the four limbs and death.
Another woman with the same condition repeatedly used wind-expelling herbs for decoction baths, resulting in abdominal distension and death.
A young woman presented with red flushes like rosy clouds, itching, and fever. She recovered using Jia Wei Xiao Chaihu Tang (Modified Minor Bupleurum Decoction) added with Sheng Di, Lian Qiao, and Dan Pi.
Jiechuang (Scabies) belongs to Damp-Toxin accumulation and Heat in the Spleen Meridian, or Blood-Heat and Wind-Heat in the Liver Meridian, or Yin-deficiency Fever in the Kidney Meridian. If accompanied by body fatigue and poor appetite, it is Damp-Heat in the Spleen Meridian; use Chushi Weiling San (Dampness-Draining Stomach-Lingzhi Powder). If scratching causes pain, it is Wind-Heat; use Danggui Yinzi (Angelica Decoction). If constipation causes pain, it is Heat-Toxin; use Shengma Heqi Yin (Cimicifuga Harmonizing Qi Drink). If there is heat, thirst, and normal bowel movements, it is deficient Heat in the Spleen and Lung; use Zhuye Shigao Tang (Bamboo Leaf and Gypsum Decoction). If there is internal heat, evening fever, or alternating chills and fever, it is Liver Meridian Blood deficiency with Wind-Heat; use Jia Wei Xiaoyao San and Liuwei Wan. If there is body fatigue, reduced food intake, night sweats, or insomnia, it is Spleen Qi stagnation; use Jia Wei Guipi Tang (Modified Heart-Spleen Replenishing Decoction), Xiaoyao San, and Dihuang Wan (Rehmannia Pill). If there is fever, night sweats, expectoration, or dry mouth, it is Kidney Meridian deficient Heat; use the ingredients of Liuwei Wan as a decoction.
Case Records:
Li Longgang, an official of the Jixun office, suffered from this all over his body, especially on the legs and feet. Symptoms worsened in the afternoon, with dry mouth, thirst, frequent dark urine. This was Kidney Meridian deficient Heat; he recovered using Buzhong Yiqi Tang and Liuwei Wan.
A scholar suffered from sneezing and itching. I considered this due to internal Damp-Heat, loose Cou Li, and external pathogen aggression. I treated him with Buzhong Yiqi Tang added with Baizhi and Chuanxiong.
Another scholar had lesions on his arms and legs, experiencing itching or distension in the afternoon, with physical fatigue. After self-medicating with Baidu San, the painful areas swelled, and urination became red and difficult. This indicated Lung and Kidney Yin deficiency. I treated him with Buzhong Yiqi Tang added with Wuweizi and Maidong, resulting in recovery.
A scholar suffering from this condition mistakenly used purgative agents, causing Yuan Qi deficiency and failure to recover. Using Buzhong Yiqi Tang added with Fuling, his sores healed suddenly. However, due to improper convalescence, symptoms worsened in the afternoon. He was treated with Bazhen Tang (Eight-Treasure Decoction) added with Wuweizi and Maidong for over fifty doses, leading to recovery.
A man presented with dark complexion, itching, and discharge of black blood, with symptoms worsening in the afternoon. His legs swelled during the day and subsided at night. I diagnosed this as Qi and Blood deficiency with Heat. He took Buzhong Yiqi Tang in the morning and Jia Wei Xiaoyao San in the evening, resulting in recovery.
A man contracted this after recovering from an epidemic. Using the aforementioned drugs for nourishment led to recovery. Another patient with the same condition died after undergoing Bianfa (bloodletting with stone needles). This was due to Yin deficiency and Blood-Heat causing dark color and itching. Why did they harm Yin and Blood?
A woman suffered from this for a long time without cure, with poor appetite and body fatigue. This was Liver and Spleen deficiency causing deficient Heat. Initially, I used Buzhong Yiqi Tang added with Chuanxiong and Chao Shanzhi to gradually restore Yuan Qi, followed by Siwu Tang combined with Xiao Chaihu Tang. After the heat subsided, I switched to Xiaoyao San to tonify the Spleen and Stomach and generate Yin Blood. Some patients presenting with chills and fever resembling malaria were also treated with these formulas.
