Antifatigue and Anti-Inflammatory Effects of Cervus elaphus L., Angelica gigas Nakai, and Astragalus membranaceus Bunge Complex Extracts in Physically Fatigued Mice

Abstract

Fatigue is a common complaint among people under stress, causing an array of negative effects on physical function. In this study, we investigated the antifatigue and anti-inflammatory effects of Cervus elaphus L., Angelica gigas Nakai, and Astragalus membranaceus Bunge complex extracts (CAA) using a treadmill stress test in animal models. The mice were administered various doses of CAA (50-200 mg/kg bw per day) once daily for 21 days. After exhaustive treadmill exercise, the running time of CAA-treated mice increased 1.5 times; fatigue-related biochemical parameters, including lactate dehydrogenase (similar to 30%), creatine kinase (similar to 20%), and proinflammatory cytokines interleukin (IL)-1 beta (similar to 10%), and IL-6 (similar to 10%) in the serum and muscle tissue were downregulated compared with those in exercised control mice. This study provides strong evidence for the prevention of CAA-induced inflammatory incidences mediated by the blockade of nuclear factor-kappa B activation. Collectively, our results indicate that CAA can alleviate symptoms of fatigue in mice as an effective anti-inflammatory agent.
