Effect of Stellaria media Tea on Lipid Profile in Rats

Abstract

Background. In folk medicine, common chickweed (Stellaria media) has traditionally been applied for the treatment of hypercholesterolemia; however, there is no firm experimental proof to support the rationale of this practice. Therefore, we aimed to assess the efficacy and safety of Stellaria media tea in hypercholesterolemic rats. Materials and Methods. Adult male Wistar rats were divided into 3 groups. The (i) control group received standard laboratory chow, the (ii) hypercholesterolemic group received cholesterol-enriched diet, and the (iii) chickweed-treated hypercholesterolemic group received cholesterol-enriched diet and 100 mg/kg body weight Stellaria media tea lyophilizate for 8 weeks. Blood samples were collected to determine serum lipid profile as well as liver and kidney function, and echocardiography was performed to assess cardiac morphology and function. Results. Cholesterol-enriched diet significantly increased serum total cholesterol, LDL- and HDL-cholesterol levels, but did not affect triacylglycerol concentrations. The addition of chickweed to the diet did not cause any significant change in serum lipid profile or body weight increase. Liver and kidney functions were unaltered and cardiac morphology and function were not changed due to Stellaria media tea lyophilizate. Conclusion. Although chickweed does not seem to be toxic, our results do not support the rationale of its use in the treatment of hypercholesterolemia.
