Thirteen-week oral toxicity study of fermented ginseng, GBCK25, in Sprague-Dawley rats

Zusammenfassung:Ginseng (Panax ginseng) is commonly used in Asia as a medicinal herb. In particular, fermented ginseng, GBCK25, has been recently developed to increase ginsenoside absorption. It also has other beneficial biological effects such as hemodynamic and anti-inflammation functions. Here, we investigated the potential toxicity of GBCK25 in Sprague–Dawley rats following 13 weeks of GBCK25 treatment by oral gavage at doses of 250, 500, or 1000 mg/kg/day and reversible toxic effects over a 4-week recovery phase. Ten male and female rats per group were randomly allocated to the main toxicology groups and five male and female rats per group were allocated to the 0 and 1000 mg/kg/day recovery groups, respectively. There was no mortality; significant clinical toxicity or microscopic findings; and changes in body weight, food consumption, hematological parameters, serum biochemistry, or absolute and relative organ weights in any of the groups. In conclusion, there were no toxicological changes upon repeated oral gavage of GBCK25 at doses of 250, 500, or 1000 mg/kg/day in Sprague–Dawley rats over 13 weeks. The no-observed-adverse-effect level of GBCK25 was 1000 mg/kg/day in both sexes of Sprague–Dawley rat. •Oral toxicity of 13-week repeated-dose of GBCK25 was tested in SD rats.•No-observed-adverse-effect level of GBCK25 was 1000 mg/kg/day in SD rats.•Our results support the safety of GBCK25 as a functional herbal supplement.
