Results:weijian obviously shortened the latent period of erection in castrational rats after electric stimulus and the latent period of coitus in castrational mice,increased coitus times in castrational mice,increased the appearance rate of sperm suppository in copulated female mice. the acute toxicity tests showed that the half lethal dose(ld50) of weijian was 901.53 mg/kg and 319.60 mg/kg, the long-term toxicity tests showed that large dose of weijian slightly increased the level of glutamic pyruvic transaminase and decreased the glucose,triglyceride and cholesterol of blood, while had no effects on other biochemical factors.
