Commentary states: Wind-heat and other toxic pathogens, remaining in the fu-organs (hollow organs) and manifesting in the muscles, give rise to sores and boils. When the disease subsides and the sores heal, residual toxins are not yet eradicated; therefore, although the scabs have fallen off, the keloids (scar tissue) remain. The treatment methods include both topical applications of moisturizing ointments and rely on the balance of Ying (Nutrient Qi) and Wei (Defensive Qi), warmth of the skin, and responsiveness of Qi. Externally, one must be cautious against wind and cold.
