The invention discloses an application of a thladiantha dubia bunge root extract to the preparation of anti-inflammatory drugs or / and analgesics. Proved by experimental researches for a plurality of yThe invention discloses an application of a thladiantha dubia bunge root extract to the preparation of anti-inflammatory drugs or / and analgesics. Proved by experimental researches for a plurality of years, the thladiantha dubia bunge root extract has strong anti-inflammatory and analgesic actions, high efficiency and low toxicity, does not generate addiction, has no obvious side effect and has morears, the thladiantha dubia bunge root extract has strong anti-inflammatory and analgesic actions, high efficiency and low toxicity, does not generate addiction, has no obvious side effect and has more remarkable advantages than the prior central analgesics and antipyretic analgesics. The thladiantha dubia bunge root extract can be a thladiantha dubia bunge root water extract or a thladiantha dubie remarkable advantages than the prior central analgesics and antipyretic analgesics. The thladiantha dubia bunge root extract can be a thladiantha dubia bunge root water extract or a thladiantha dubia bunge root alcohol extract, the thladiantha dubia bunge root water extract is an extract obtained by routine techniques, such as crushing a thladiantha dubia bunge root dry product, adding water, dea bunge root alcohol extract, the thladiantha dubia bunge root water extract is an extract obtained by routine techniques, such as crushing a thladiantha dubia bunge root dry product, adding water, decocting, filtering, mixing filtrate, centrifugalizing supernatant fluid, decompressing, compressing, and the like, and the thladiantha dubia bunge root alcohol extract is an extract obtained by routincocting, filtering, mixing filtrate, centrifugalizing supernatant fluid, decompressing, compressing, and the like, and the thladiantha dubia bunge root alcohol extract is an extract obtained by routine techniques, such as crushing a thladiantha dubia bunge root dry product, refluxing with alcohol, extracting, filtering, mixing filtrate, centrifugalizing supernatant fluid, decompressing, compressine techniques, such as crushing a thladiantha dubia bunge root dry product, refluxing with alcohol, extracting, filtering, mixing filtrate, centrifugalizing supernatant fluid, decompressing, compressing, and the like. The two extracts can be directly used for preparing the anti-inflammatory drugs or / and the analgesics.g, and the like.
