28-day repeated-dose toxicity of orally administered Jinmao Jiedu granule in Sprague-Dawley rats

Jinmao Jiedu granule is a Chinese medicine preparation consisting of Actinidia valvata Dunn, Salvia chinensis Benth, Iphigenia indica Kunth, and chicken gizzard. For many years, it has been employed in adjuvant therapy for cancer, especially liver cancer. However, the potential toxicity of the granule has not been reported. The present study aimed to assess the repeated-dose toxicity of orally administered Jinmao Jiedu granules for Sprague-Dawley (SD) rats. SD rats were orally administered Jinmao Jiedu granules at doses of 2.85, 5.70, and 11.40 g/kg in a 28-day subchronic toxicity study. No adverse clinical signs associated with treatment were noted throughout the experiment. There were no treatment-related toxicity alterations in body weight, hematology, clinical biochemistry, urinalysis, necropsy, and histopathology in rats compared with the control group. The No Observed Adverse Effect Level (NOAEL) of the Jinmao Jiedu granule was higher than 11.40 g/kg/day in rats.
