Abstract

Objectives: The herb of Agastache rugosa (AR) is a traditional herbal medicine used for colds, vomiting and furuncles. However, there are few reports to investigate the inhibitory effects of AR on obesity. In this study, the effects of AR on high fat diet (HFD)-induced obesity and its mechanism of actions were investigated in experimental animals. Methods: The mice were fed HFD for 4 weeks to induce obesity. After randomly divided into normal fat diet, HFD and AR groups, 200 mg/kg of AR was administrated for 4 weeks with continuous HFD feeding while vehicle was orally treated to HFD group. Food intake and body weight were recorded weekly. Results: Increased body weight by HFD was improved by AR treatment. AR administration inhibited an increase of visceral fat weight as well as adipocyte hypertrophy. Hepatic steatosis was ameliorated in AR-treated mice. In addition, treatment of AR attenuated the expression of adipogenic transcription factor, peroxisome proliferator-activated receptor (PPAR)-gamma in the epididymal adipose tissue. Also the increased serum leptin level by HFD was maintained in AR group, leading to inhibition of food intake. Conclusions: AR treatment showed inhibitory effects on HFD-induced obesity by inhibition of PPAR-gamma and reduction of food intake. AR could be an alternative treatment for obesity.
