Toxicopathological Evaluation of Hydroethanol Extract ofDianthus basuticusin Wistar Rats
Background. Dianthus basuticusis a commonly used medicinal plant in Basotho traditional medicine for the treatment of diabetes, but there is no report on its safety or toxicity. Therefore, we evaluated the toxicity profile of the hydroethanol whole plant extract ofDianthus basuticusin Wistar rats.Methods.Acute toxicity test was performed with single oral administration of 100–3200 mg/kg body weight ofD. basuticusextract to rats and the animals were observed for 14 days for signs of toxicity. The subacute toxicity experiment was conducted by oral administration of graded doses (200, 400, and 800 mg/kg) ofD. basuticusextract daily for 28 days. Behavioural changes as well as haematological, biochemical, and histological parameters were then evaluated.Results.There was no observable sign of toxicity in the acute toxicity test. There were significant decreases (P<0.05) in the feed and water intake as well as total cholesterol and triglycerides of theD. basuticusextract-treated rats in subacute toxicity study. There were no treatment related differences in the haematological, biochemical, and histopathological evaluations.Conclusions.Administration of hydroethanol extract ofD. basuticusmay be safe at the dosages tested in this study but its continuous usage can cause anorexia.
