The purpose of this study was to investigate the acute and sub-chronic toxicity of honokiol microemulsion. In the acute toxicity tests, the mice were intravenously injected graded doses of honokiol microemulsion and were observed for toxic symptoms and mortality daily for 14 days. In the sub-chronic toxicity study, rats were injected honokiol microemulsion at doses of 100, 500, 2500 mu g/kg body weight (BW) for 30 days. After 30 days treatment and 14 days recovery, the rats were sacrificed for hematological, biochemical and histological examination. In the acute toxicity tests, the estimated median lethal dosage (LD50) was 50.5 mg/kg body weight in mice. In the sub-chronic toxicity tests, the non-toxic reaction dose was 500 mu g/kg body weight. In each treatment group, degeneration or/and necrosis in vascular endothelial cells and structure change of vessel wall can be observed in the injection site (cauda vein) of a few animals while there were no changes in the vessels of other organs. The overall findings of this study indicate that the honokiol microemulsion is non-toxic up to 500 mu g/kg body weight, and it has irritation to the vascular of the injection site which should be paid attention to in clinical medication.
