Abstract

<abstract> <title>Abstract</title> <p> <italic>Vitex negundo</italic> is a common herb in different herbal formulation. The potential acute and sub-chronic dermal toxicities were evaluated as per OECD (Organization for Economic Cooperation and Development) guidelines 402 and 411, respectively. Both sexes of Wistar rats were exposed to <italic>Vitex negundo</italic> oil of 2000 mg/kg body weight for acute dermal toxicity, whereas in the dermal sub-chronic toxicity study, rats were exposed to <italic>Vitex negundo</italic> oil 250, 500 and 1000 mg/kg body weight, respectively, for five times a week for 90 d. In acute and sub-chronic toxicity studies, all animals were normal without any behavioral, serum biochemistry, hematology, necroscopical and histopathological changes. The no observed effect level (NOEL) and no observed adverse effect level (NOAEL) of <italic>Vitex negundo</italic> oil were 250 and 1000 mg/kg/day, respectively. <italic>Vitex negundo</italic> oil is under the category 5 (Unclassified) according to the Globally Harmonized System, with an LD₅₀ value of over 2000 mg/kg.</p> </abstract>
