【歌】癞疾原来即疠风，遍身疙瘩痒生虫。须臾鼻塌眉毛堕，暴酷应知恶气钟。
【论】夫疠风者，大风也，古名曰癞。受得天地杀物之风，暴悍酷烈可畏。然血随气化，气既不施，血为
之聚，血聚则肉烂生虫，须臾鼻崩眉堕，不外乎阳明一经，盖阳明无物不受故也。风之入人也，气受之则上身
多；血受之则下体多；气血俱受，上下俱多。甚重，自非医者神手，病者铁心，罕有免于死者。按法治之，尤
当绝浓味，忌酒色，不致再发，再发则无救矣。知命者可以守此戒乎？

【歌诀】
癞疾原本就是疠风，全身布满疙瘩，瘙痒如生虫。
一会儿鼻子塌陷、眉毛脱落，这种暴烈酷毒之症，应当知道是恶气聚集所致。
【论述】
所谓疠风，就是大风病，古代称为癞。这是受了天地间能杀伤万物的风气，其性质暴悍酷烈，令人畏惧。然而血随气运行，气如果不通畅，血就会凝聚；血凝聚则肌肉腐烂并生出虫子，一会儿鼻子崩塌、眉毛脱落，这都不外乎阳明经（足阳明胃经和手阳明大肠经）的问题，因为阳明经无所不受的缘故。风邪侵入人体，如果气先受邪，则上半身症状多；如果血先受邪，则下半身症状多；如果气血都受邪，则上下半身症状都多。病情严重的，如果不是医生有神奇的手术，病人有坚定的意志，很少有能免于死亡的。按照法则治疗，尤其应当断绝浓腻厚味的食物，忌酒色，这样才不会再次发作，一旦再次发作就无法救治了。懂得命运的人可以遵守这些戒律吗？

[Verse]
The disease of leprosy (Laiji) is originally Leprosy (Lifeng), with nodules all over the body and itching as if insects are present.
In an instant, the nose collapses and eyebrows fall out; one should know that this violent and cruel condition is caused by the accumulation of evil qi (malicious energy).
[Dissertation]
As for Lifeng (Leprosy), it is also called "Da Feng" (Great Wind), and in ancient times was known as Lai (Leprosy). It results from receiving the wind of heaven and earth that kills living things, which is violent, fierce, and cruel, inspiring fear. However, blood follows the movement of qi; if qi does not circulate freely, blood stagnates. When blood stagnates, flesh rots and insects are born. In an instant, the nose collapses and eyebrows fall out. This does not go beyond the involvement of the Yangming channel (Stomach and Large Intestine meridians), because the Yangming channel receives everything. When wind pathogen enters the human body, if qi is affected first, symptoms appear mostly in the upper body; if blood is affected first, symptoms appear mostly in the lower body; if both qi and blood are affected, symptoms appear in both upper and lower bodies. In severe cases, unless the physician has miraculous skills and the patient has iron-like determination, few will escape death. According to the prescribed methods of treatment, one must especially abstain from rich and greasy foods, avoid alcohol and sexual indulgence, so as not to cause recurrence. If it recurs, there is no cure. Those who understand destiny can observe these prohibitions?
For those with symptoms predominantly in the upper body:
Use Zuixian San (Immortal Drunken Powder) to extract foul saliva and bad blood from between the teeth.
