AI Technical Summary

Problems solved by technology

[0004] The above-mentioned dosage forms are simple, and cannot give full play to the advantages of fully combining preparations and curative effects

Existing preparation technology also has major defect in addition, and the active ingredient that senna plays decisive role is sennoside (glucoside), is very unstable material to light and heat, and existing technology adds water decoction to senna, and temperature is higher High, the sennoside (glucoside) is severely damaged, so the content of the sennoside (glycoside) in the preparation is extremely low, basically ineffective or the effect is low, seriously affecting the efficacy of the drug
