Methods Using statistical methods and SPSS software correlation analysis. Results In medicinal plants, bitter taste accounted for the largest proportion, accounting for 50% of the total, followed by the sweet taste of the total number of 17%, 14% of the total flavors category; its drug statistics, cold 29% of the total number of medicinal plants, 25% of the total number of medicinal plants, 21% of the total number of medicinal plants, 20% of the total number of medicinal plants; 33% of the total medicinal plants, 18% of the total blood medicinal plants, and 17% of the medicinal plants of the rheumatism class.
