Abstract EN
Yukmijihwang-tang (YMJ; Liu wei di huang tang (China), Rokumigan (Japan)) has been used in the treatment of diseases including renal disorder, cognitive vitality, and diabetes mellitus.
However, there is very little information regarding the toxicity of YMJ to give an assurance of safety for clinical treatment.
To provide safety information for YMJ, we evaluated its acute and sub-chronic toxicity in rats.
The single-dose toxicity of YMJ was examined using Sprague-Dawley rats.
Rats were treated with YMJ extract orally at 0, 500, 1000, or 2000 mg/kg body weight.
After a single administration, clinical signs were observed every day for two weeks, and body weights were measured five times, including an initial measurement on day 1 (the day of administration).
In the sub-chronic oral toxicity study, YMJ was administered to rats at 0, 500, 1000, or 2000 mg/kg/day for 13 weeks.
Mortalities, clinical signs, body weight changes, food and water consumption, ophthalmologic findings, urinalysis, hematological and biochemical parameters, gross findings, organ weights, and histological examination were monitored during the study period.
We found no mortality and no abnormalities in clinical signs, body weights, and necropsy findings for any of the animals in the acute and sub-chronic studies following oral administration in the rat at up to 2000 mg/kg/day YMJ.
YMJ may not have any single-dose toxicity; the LD50 of YMJ was over 2000 mg/kg, and it is safe for rats.
The no-observed-adverse-effect-level (NOAEL) was considered to be 2000 mg/kg/day.
