The invention provides an external
medicine for incontinence dermatitis and a preparation method thereof. The external
medicine is prepared from 20-35 parts of improved
grapefruit oil, 10-20 parts of biodegradable film-forming
polymer, 5-10 parts of composite anti-inflammatory agent, 8-15 parts of
astringent, 5-15 parts of emulsifier and 3-10 parts of
humectant, wherein the composite anti-inflammatory agent contains a composite extract of
cephalotaxus sinensis, fructus alpiniae oxyphyllae and
lygodium japonicum according to a
specific mass ratio. The improved
grapefruit oil is extracted through multiple steps of crushing, enzymolysis, pulsed
electric field treatment, high-pressure microjet and the like. The composite anti-inflammatory agent has a specific
water immersion ultrasonic extraction mode; all
raw material components such as a biodegradable film-forming
polymer, an
astringent and the like are also definitely formed. The preparation method comprises the steps of
raw material treatment, ultrasonic-assisted fusion, addition of other components, stirring and the like, and finally, spray, gel or cream can be prepared. The
traditional Chinese medicine composition integrates various natural and functional components, aims to provide an effective external
medicine for treating incontinent dermatitis, and is expected to improve
skin symptoms of patients and promote
skin repair.
