Effects of <i>Glycyrrhiza glabra</i>, <i>Mentha piperita</i> and their Blend Teas Infusion on Serum Lipids of Wistar Rats

Abstract

Abstract. The aim of this study was to demonstrate the effects of Glycyrrhiza glabra (Licorice), Mentha piperita (Peppermint) and their blend teas on serum lipids of Wistar rats. The animals were divided into control group (CG) and nine treated groups: P1, P3, P5 treated with peppermint tea; L1, L3, L5 treated with Licorice tea and P+L1, P+L3, P+L5 treated with blended peppermint and licorice tea of 10 mg/kg.BW/ml, 30 mg/kg.BW/ml and 50 mg/kg.BW/ml concentrations respectively. The teas were administered orally once in a day for 30 days. P3, P5; L3, L5 and P+L3, P+L5 animals showed significant decrease in triglycerides and total cholesterol and slight increase in HDL-c levels. The levels of LDL-c decreased in the treated groups compared to control group. The results suggested that supplementation with peppermint; licorice and their blend tea extracts can reduce the serum concentrations of cholesterol, triglycerides and LDL.
