Open Access Acute Dermal Toxicity Study of Bee Venom (Apis mellifera L.) in Rats

Bee venom (Apis mellifera L. BV) has been used as a cosmetic ingredient for anti-ageing, anti-inflamma-tory and antibacterial functions. The aim of this study was to evaluate the acute toxicity after a single der-mal administration of BV, BV was administered to 2 groups of Sprague-Dawley (SD) male and female rats (5 animals/group) at doses of 0 and 1,500 mg/kg body weight (BW). Mortality, clinical signs, body weight changes and gross findings were continually monitored for 15 days following the single dose. There were no unscheduled deaths in any groups during the study period. No BV related clinical signs and body weight changes were observed in any groups during the study period. There were no abnormal gross find-ings at necropsy on day 15 after the treatment. On the basis of the above results, it was concluded that there were no treatment-related effect on mortality, clinical signs, body weight changes and gross findings in SD rats treated with a single dermal dose of BV at dose of 1,500 mg/kg BW. Therefore, the approxi-mate lethal dose of BV was considered to be over 1,500 mg/kg/day for both sexes of rats. BV may pro-vide a developmental basis for a cosmetic ingredient or external application for topical uses. Key words: Bee venom, Apis mellifera, Dermal toxicity, Ra
