Effects of Rosa Roxburghii Tratt Freeze-Dried Powder on Carotid Atherosclerotic Plaques: A Real-World Study

This study aims to evaluate the effectiveness and safety of Rosa roxburghii freeze-dried powder in reducing carotid atherosclerotic plaques. Carotid atherosclerosis is a major cause of ischemic stroke, and current treatments have safety limitations. Rosa roxburghii, a fruit used in traditional Chinese medicine, has shown potential in lowering lipids and reducing inflammation. In this randomized controlled trial, 200 participants with carotid plaques will be assigned to either conventional therapy alone or conventional therapy plus Rosa roxburghii freeze-dried powder (3 g/day for 6 months). The primary outcomes are changes in plaque size assessed by ultrasound and serum lipid levels. Secondary and exploratory outcomes include changes in inflammatory markers, gut microbiota composition, and metabolomic profiles. The study will provide clinical evidence on the use of Rosa roxburghii as an adjunctive therapy for atherosclerosis.
