The invention discloses a preparation method of a
traditional Chinese medicine external
liniment for treating viral warts, and relates to the technical field of
traditional Chinese medicine external preparations, and the preparation method sequentially comprises the following steps:
raw material pretreatment: respectively taking seven medicinal materials including horsetail, prepared
cantharides,
cyperus rotundus, prepared
arisaema consanguineum schott, raw rhubarb,
angelica dahurica and wild
agastache rugosus, washing, and
drying at 50-65 DEG C until the
moisture content is less than or equal to 10% to obtain dried medicinal materials; the formula aims at the
pathogenesis of heat
toxin accumulation and qi and
blood stasis of
virus warts, the compatibility of monarch, minister, assistant and guide is rigorous, the core medicines such as the processed
cantharides and the raw rhubarb have the effects of directly corroding warts and inhibiting viruses, and the alkalization auxiliary materials are combined, so that the
medicine can more effectively act on wart tissues with abnormal
hyperplasia, and the effect of treating the warts is achieved. The process
route of low-temperature
drying, co-crushing, alkalization and long-time cold soaking is adopted, the damage of high-temperature decoction to effective components (especially
cantharidin and the like) is avoided, the efficient and sufficient extraction of the
active components is realized through long-time soaking and alkalization environment, and the stability of the
efficacy of the preparation is ensured.
