古人将疯病称为“疠疯”，又名为“恶疾”。黑白癞、赤白癜，都属于这一类疾病。但是，癜癞这类病麻木的情况较少，而疯病则没有不出现麻木症状的。丹溪说：麻的感觉只是像风吹一样轻微，尚且有气血相互冲撞的状态；木则是气血已经痹阻而不感觉痛痒，不知道疼痛和瘙痒。疠疯初起时，手足必然先出现麻木，然后皮肤才会损伤溃烂。《灵枢》说：卫气运行不畅，就会导致麻木。《素问》说：营气虚弱则身体不知痛痒（不仁），卫气虚弱则肢体不能运动（不用）。营气和卫气都虚弱，就会既不知痛痒又不能运动。另外，《素问·脉要精微论》提到：脉象因风邪变化而成疠疯。又说风寒邪气客居在脉中而不离去，称为疠疯。疠疯的病机是营卫有热，其气不清爽。薛氏则认为这是外邪侵袭，卫气内伏，湿热日久，血液随火邪化热所致。所以治疗者应当以凉血和血为主，驱风除湿为辅，以各经引经药为使药，稍加清热解毒的药物，没有不能痊愈的。但应当根据病情的轻重，分别采取内外治法。
这是疯门中的灵活治法，领悟之后就可以随证候加减运用，随手就能取得春回大地般的疗效。如果拘泥成法不知变通，反而失去了制方的本意。

(The pathogenic factor) accumulates in the sinews and collaterals, and coagulates in the skin. Since there are many affected areas, it is difficult to treat from the interior; therefore, external treatment is appropriate.

In ancient times, this disease was called "Li Feng" (Leprosy/Madness), also known as "E Ji" (Vile Disease). Black and white leprosy (Hei Bai Lai), red and white vitiligo-like patches (Chi Bai Dian) all belong to this category. However, cases of numbness in Lai/Dian are few, whereas Feng invariably presents with numbness. Danxi stated: "Ma" (numbness/tingling) feels merely like a slight breeze, still retaining the sensation of Qi and Blood rushing; "Mu" (wooden/insensate) indicates that Qi and Blood have become bi-occluded and insensate, unaware of pain or itching. When Li Feng first begins, the hands and feet must first become numb, followed by damage and ulceration of the skin. The *Ling Shu* states: "When Wei Qi fails to circulate, it results in numbness." The *Su Wen* states: "When Ying Qi is deficient, there is insensibility (Bu Ren); when Wei Qi is deficient, there is paralysis/inability to move (Bu Yong). When both Ying and Wei Qi are deficient, there is both insensibility and inability to move." Furthermore, the *Su Wen: Mai Yao Jing Wei Lun* mentions: "Pulse changes due to Wind constitute Li Feng." It also states: "When Cold and Wind pathogens lodge in the vessels and do not depart, it is named Li Feng." The pathology of Li Feng involves heat in Ying and Wei Qi, resulting in turbid Qi. Xue Shi further believed this was caused by external pathogens invading, with Wei Qi lying dormant internally; long-standing Damp-Heat causes Blood to transform with Fire. Therefore, treatment should primarily focus on Cooling Blood and Harmonizing Blood, assisted by expelling Wind and removing Dampness, using channel-guiding herbs as messengers, and slightly adding Heat-clearing and Toxin-resolving agents. There is no case that will not be completely cured. However, one must distinguish between severity and internal/external aspects for treatment.
This represents the flexible methods within the Feng Men school. Once comprehended, prescriptions can be modified according to syndromes, yielding spring-like vitality upon application. If one sticks rigidly to formulas without adaptation, one loses the original intent of prescription formulation.
