Problems solved by technology

But the shortcoming that some cataplasms exist at present is mainly that the adhesiveness between the paste and the skin is not good, and it is easy to slip off from the affected part of the skin when sticking, especially the joints with large activities; Hardens with water, or loses stickiness by absorbing sweat from the skin when applied
CN 03134370.8 discloses sinomenine hydrochloride spray and its preparation method, but there are obvious defects in the skin spray, that is, the mist solution is easy to flow, making it difficult to accurately position the drug, and it is easy to contact with clothing, and it needs to be massaged by hand to treat it. Make the medicine more effective
