【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？

[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.

Effect is seen in five to seven days. Adjust the dosage according to the size and deficiency/excess condition of the patient.
