[Applying collateral disease theory to treat chronic dermal ulcer].

ABSTRACT

Collateral disease theory has been applied to investigate the pathogenesis of chronic dermal ulcer in traditional Chinese medicine. It is suggested that deficiency of vital qi is the pathological basis of chronic dermal ulcer with collaterals stagnation as the major pathological factor, and collaterals impairment by toxin evil is the main pathological change. The important principle in treatment of chronic dermal ulcer is established as strengthening the body resistance, dredging collaterals and removing toxins, and this enriched the theory of wound healing in traditional Chinese medicine, and has practical value.
