In recent years, there has been a growing trend in the usage of traditional medicine and herbal treatments. However, the misconception that they are completely safe resulted in irreversible complications and damages. The present study was conducted to investigate the potential renal toxicity of a commonly used drug in Iran's traditional medicine and pharmacy, known as Zaravand Gerd or Nokhod Alvand (Aristolochia rotunda L.). In Iranian traditional medicine, Zaravand Gerd is used as a remedy for respiratory system ailments, back pain, anxiety, headache and septic wounds. Fifty-six male rats were divided into seven groups (n = 8). The first group served as the control and received normal saline, while the second to seventh groups were administered varying doses of the aqueous extract of Zaravand Gerd (0.1, 0.5, 1.25, 2.5, and 5 g/kg) for a period of three weeks. Various parameters were measured to evaluate the potential kidney damage caused by the extract, including serum creatinine and BUN levels, as well as urine protein and glucose levels, which were analyzed using an autoanalyzer. Additionally, kidney tissue samples were examined pathologically, and mitochondria from the kidney tissue were isolated to assess mitochondrial parameters. The results of this study revealed that high doses of Zaravand Gerd extract led to a significant increase in urinary glucose and protein excretion compared to the control group. Pathological examination of the isolated kidney tissues indicated that the concentrations of 2.5 and 5 g/kg of Zaravand Gerd extract resulted in kidney damage and dilation of proximal convoluted tubules. Furthermore, the study demonstrated that high doses of the extract (2.5 and 5 g/kg) caused damage to the mitochondria. Based on the findings of this study, it can be concluded that the administration of high doses of Zaravand Gerd extract, which are not commonly used in traditional medicine, can have toxic effects on the kidneys in rats as an animal model. These results highlight the importance of considering the potential risks associated with herbal medicines and the necessity of usage based on scientific evidence.
