Preparation method of externally applied powder for treating sudden hearing loss

Abstract

The invention discloses a preparation method of an externally applied powder for treating sudden hearing loss in order to treat the sudden hearing loss. The externally applied powder is characterized by being prepared from the following crude drugs in weight ratio: begonia handelii irmsch., fructus cinnamomi, mosla chinensis maxim, dracocephalum moldavica L., Chinese honeylocust spines, medlar, dipsacus asperoides, acorus tatarinowii schott, petals of helianthus annuus L., turbo cornutus solander, bos taurus domesticus gmelin and caryopteris incana. The preparation method of the externally applied powder comprises the following steps: (1) extracting volatile oil from coarse powders of the dipsacus asperoides, fructus cinnamomi and Chinese honeylocust spines for later use; (2) smashing the turbo cornutus solander and the bos taurus domesticus gmelin into fine powder for later use; (3) adding the begonia handelii irmsch., the mosla chinensis maxim, the dracocephalum moldavica L., the medlar, the petals of helianthus annuus L., the acorus tatarinowii schott and the caryopteris incana into water for decocting twice, filtering, merging filtrates, concentrating the merged filtrate, adding ethanol for settling, taking a supernatant, recovering the ethanol and concentrating to obtain a thick paste; and (4) adding the volatile oil obtained in the step (1) and the fine powder obtained in the step (2) into the thick paste obtained in the step (3), uniformly stirring, drying, smashing and sieving by using a 100-mesh sieve to obtain the externally applied powder. Clinical experiments prove that the externally applied powder has the characteristic of good curative effect when used for treating sudden hearing loss, and is worthy of clinical application and popularization.
