五脏中都有虫。虫遇到风就会化生。肺开窍于鼻。如果肺经虚弱，风热之邪就会乘虚而入，导致鼻气壅塞，不能宣通。
这样疳虫就能趁机侵蚀，在鼻间生出疮疡。

There are insects (parasites) in all five Zang organs. These insects transform when exposed to wind. The Lung opens into the nose. If the Lung meridian is deficient, wind-heat pathogens take advantage of this deficiency. Nasal qi becomes obstructed and cannot circulate freely.
Consequently, gan insects (parasites associated with malnutrition/toxicity) can erode tissues, causing sores to form in the nose.
