Effect of tao-hong-si-wu-tang, a traditional Chinese herbal medicine formula, on physical fatigue in mice.

Tao-Hong-Si-Wu-Tang (THSWT) is a famous traditional Chinese herbal medicine formula, which has traditionally been used in China for about one thousand years. The present study investigated the effect of THSWT on physical fatigue. 32 male mice were randomly divided into 4 groups with 8 in each group. All were administered orally and daily for 28 days. Group I received isotonic saline solution as control; Group II, III and IV obtained 5, 10 and 20ml/ kg body weight of THSWT solutions, respectively. After 28 days, the anti-physical fatigue effect of THSWT was evaluated by using a forced swimming test, along with the determination of blood lactic acid, blood urea nitrogen (BUN), liver glycogen and muscle glycogen contents. The data showed that THSWT could extend exhaustive swimming time of mice, as well as decrease the BLA and BUN contents and increase the liver glycogen and muscle glycogen contents. The results support that THSWT had anti-physical fatigue effect.
