Single-and repeated-dose toxicities of Erinacol<SUP>®</SUP> extract of Hericium erinacium cultivated with Artemisia iwayomogi, were evaluated according to "Guidelines for Toxicity Tests of Drugs and Related Materials" of Korea Food and Drug Administration using Sprague-Dawley rats. For single-dose toxicity study, Erinacol<SUP>®</SUP> was dissolved in drinking water, orally administered and examined for 14 days. As results, Erinacol<SUP>®</SUP> up to the limited dose of 5,000 ㎎/㎏ neither induced death, clinical signs and necropsy findings, nor affected body weight gain and organ weights, in which 10% lethal dose could not be estimated. Based on the results of single-dose toxicity test, Erinacol<SUP>®</SUP> was administered at doses of 500, 1,000 or 2,000 ㎎/㎏ for 28 days for the evaluation of repeated-dose toxicity. All doses including the limited dose (2,000 ㎎/㎏) of Erinacol<SUP>®</SUP> did not cause any abnormalities of rats, including mortality, clinical signs, body weight gain, feed/water intake, necropsy findings, hematology, blood biochemistry and organ weights. Rather, high doses (1,000-2,000 ㎎/㎏) of Erinacol<SUP>®</SUP> reduced the serum levels of alanine transaminase (ALT), aspartate transaminase (AST), creatinine phosphokinase (CPK) and lactate dehydrogenase (LDH), indicative of protective effects on hepatic and muscular injuries. Thus, both maximum tolerable dose (MTD) and no observed adverse effect level (NOAEL) were not determined. The results indicate that long-term intake of high-dose Erinacol<SUP>®</SUP> might not induce general adverse effects.
