However, no studies have been carried out to ensure the plant's safety. This work aimed to assess the acute and subacute toxicity of the aqueous extract of Ficus vallis-choudae (FVE) leaves in rats. To assess acute toxicity, FVE at a single dose of 5000 mg/kg was administered to female rats (n = 6), while distilled water (1 mL/100 g) was force-fed to animals in the control group (n = 6). Behavioral changes and mortality were assessed at 30 min, 4h, 24h, 48h and regularly for 14 days. For the subacute toxicity study, animals were divided into 6 groups of 10 rats each (5 males and 5 females) and treated orally for 28 days. A control group received distilled water (10 mL/kg), three groups received FVE at doses of 220, 440 and 880 mg/kg respectively, and two satellite groups received distilled water (10 mL/kg) and FVE at 880 mg/kg respectively. Body mass, food and water consumption, biochemical, and hematological parameters, and liver and kidney histology were evaluated. For acute toxicity, no behavioral changes and no mortality were observed. The mean lethal dose (LD50) of FVE was greater than 5000 mg/kg. With regard to subacute toxicity, the FVE tested appeared to be tolerated by rats, as no major clinical signs of toxicity, no mortality, no significant changes in body weight, internal organ weights, food and water consumption were noted in either female or male rats. Similarly, biochemical and hematological parameters, as well as histological aspects of the liver and kidneys of FVE-treated animals of both sexes, showed no significant changes. Short- and medium-term consumption of FVE is safe in rats. However, it will be useful to assess the sub-chronic and chronic toxicity of this plant extract. 12 31 2024 437 444 1 10.31254/biomed-crossmark-policy www.biomedresearch.org false 10.31254/phyto.2024.13603 https://www.phytopharmajournal.com/assets/pdf_files/Vol13_Issue6_03.pdf
