[Preliminary exploration on knockout drops (Meng Han Agents)].
This author points out, based on relevant materials, that knockout drops were vertigo powder. Due to homophonic reasons in Chinese language, the term "mingxuan" was transliterated into the former Chinese term (menghan). Knockout drops for medicinal use were merely made up of compound recipes containing stramonium flowers. The knockout drops in old fictions and opera books were powder of stramonium flower. The ingredients and application of such recipes are discussed here, the anti-remedies for such recipes are also mentioned.
