The invention discloses an externally-used
traditional Chinese medicine preparation for treating eczema and
psoriasis and a preparation method thereof. The externally-used
traditional Chinese medicine preparation is prepared from the following raw materials: 25 to 50 parts of lightyellow
sophora root, 25 to 50 parts of fructus kochiae, 20 to 40 parts of cortex dictamni, 20 to 40 parts of radix et rhizoma rhei, 20 to 40 parts of herba portulacae, 10 to 30 parts of radix saposhnikoviae, 10 to 30 parts of herba schizonepetae, 5 to 20 parts of alumen, 8 to 15 parts of fructus cnidii, 20 to 40 parts of radix sanguisorbae, 5 to 20 parts of fructus gardeniae and 20 to 40 parts of
siegesbeckia orientalis. The preparation method comprises the following steps: putting and soaking smashed radix et rhizoma rhei into cold water, then adding the alumen and hot water, and carrying out
percolation after dissolving the alumen into the hot water, thus obtaining percolate; then carrying out twice decocting on a mixture of other slices, and standing and filtering two filter solutions after decocting, thus obtaining a concentrated solution; finally, after uniformly mixing the prepared
percolation with the concentrated solution, adding
sodium benzoate, thus preparing the externally-used
traditional Chinese medicine preparation for treating the eczema and the
psoriasis. The externally-used traditional Chinese
medicine preparation disclosed by the invention not only is high in
recovery rate, low in recurrence rate and small in
irritation, but also has no any toxic and side effects after long-term use.
