Abstract: Objective: To evaluate the safety and immunomodulatory activity of the combination of Paecilomyces hepiali and Cordyceps militaris. Method: Acute toxicity test in mice, bone marrow cell micronucleus test in mice, sperm malformation test in mice, microsomal enzyme(Ames)test, delayed metamorphosis test in mice, serum hemolysin titer detection and spleen cell antibody - producing cell assay were used to observed to determine the toxicity and immune effect. Result: The maximum tolerated oral acute toxicity of the compound in mice was

>20.0 g/kg bw, which was a non-toxic substance, and the mouse bone marrow cell micronucleus test, sperm malformation test and Ames test were negative; in the cellular immunity test, the medium (0.33 g/kg bw) and high

(0.99 g/kg bw) doses of the compound significantly increased the difference in foot and plantar thickness in mice (medium dose: p
