MATERIALS AND METHODS

The study examined 13 original studies that included ethnobotanical research conducted in East Africa. They were retrieved from several internet databases, including Google Scholar, Scopus, PubMed/Medline, Science Direct, and Research for Life. The study retrieved databases on plant families and species, plant parts used, preparation methods and routes of administration, and the country where the ethnobotanical field surveys were conducted. Graphs were produced using the GraphPad Prism 8.125 program (GraphPad Software, Inc., San Diego, CA). Tables and figures were used to present the data, which had been condensed into percentages and frequencies.

RESULTS
