Acute and Subchronic Toxicological Evaluations of Allium rotundum L.: A Dietary Plant from Iran

Allium rotundum L. is a dietary plant with diverse nutritional and herbal applications. According to its widespread application in Iranians’ diets, understanding the possible adverse effects and toxic activities could be of major importance. The aim of this study was to establish the acute and subchronic toxicity profile of the hydroalcoholic extract of Allium rotundum on male and female Wistar rats. The acute study indicated no adverse effect or toxic activity after administration of the extract, suggesting that the LD50 value is up to 5,000 mg/kg body weight for the extract. The subchronic study at three doses (250, 500, and 750 mg/kg body weight/day) supported the results of acute study and revealed that no abnormal change or toxicity was induced by the extract in both male and female Wistar rats. All the biochemical and hematological parameters of the treated rats were in historical range after long-term administration of the extract. The histopathological examination also revealed no lesion o...
