Background: Carissa edulis is widely used in traditional medicine to manage numerous ailments. However, few studies have assessed its toxicity. Therefore, this study aimed to determine acute and sub-toxicity levels of C. edulis methanol extract. Methods: In the acute toxicity probe, a limit test was conducted whereby the extract was given as a solo dose by gavage. The rats were observed for two weeks. The observations included mortality and changes in the general appearance and behavior of the experimental animals. The body weights of the rats were taken weekly. For the sub-acute toxicity probe, the rats received the extract daily at dosages 300, 520, and 900 mg/kg by gavage for 28 days. Body weights were also taken weekly. On day twenty-nine, the weights of the rats were taken, the rats were sacrificed, and blood was collected for biochemical and hematological analysis. Body organs were harvested, and their weights were taken. Results: The results of the acute toxicity probe showed that the extract didn{\textquoteright}t cause mortality or toxicity signs throughout the study duration. The LD50 of the extract was therefore deemed to be above 2,000 mg/kg. The sub-acute toxicity probe results demonstrated that the extract, at all the tested dosages, didn{\textquoteright}t cause mortality or affect the rats{\textquoteright} organ weights, body weights, or hematological and biochemical parameters throughout the study duration. Conclusions: In conclusion, the methanol extract of C. edulis is not toxic since it didn{\textquoteright}t cause mortality or toxicity signs in both acute and sub-acute toxicity probes.

Crataegus aronia is widely known for its antioxidant, anti-inflammatory, and hypolipidemic properties, and it has traditionally been used to treat cardiovascular disorders. This study aimed to evaluate the impact of Crataegus aronia extract on the liver enzyme markers, blood glucose levels, lipid profiles, and kidney function biomarkers as well as hematological parameters in induced diabetic rats. Male Wistar rats were divided into seven groups: normal Control; Diabetic; and Diabetic animals treated with two doses of Crataegus aronia extract (5 and 10mg/kg) (DM + extract), Control treated with the extract ( 5 and 10mg/ kg) and induced diabetic treated with insulin. Streptozotocin (STZ)-induced diabetic rats (50 mg/kg, ip)and normal were orally administrated with Crataegus aronia extract once a day for 4 weeks. At the end of the experiment, the biochemical and hematological parameters were measured in all groups. Also, the phytochemicals and antioxidant activity of the Crataegus aronia extract were evaluated. According to findings, the total phenols, total flavonoid, and flavonol contents were 538.3 mg Galic acid equivalent /g extract, 149.3 mg Rutin equivalent / g extract, and 79.3 mg Rutin equivalent / g extract), respectively. The antioxidant activity according to 2,2-diphenyl-2-picrylhydrazyl (DPPH) IC50 and ferric reducing antioxidant power (FRAP) assays were 28.02 μg/ml and in the range of 0.273 {\textendash} 0.960 μmol Fe+2/g dw, respectively. Crataegus aronia extract significantly (p \<0.05) affects red blood cells, hemoglobin, hematocrit, white blood cells, lymphocytes, and platelets values. Also, Crataegus aronia had a significant (P \< 0.05) effect on serum biochemical parameters, including glucose, total proteins, albumins, triglycerides, creatinine, bilirubin, and serum aspartate aminotransferase (AST). However, Crataegus aronia treatment had no significant effects (p \< 0.05) on serum alanine aminotransferase, alkaline phosphatase, and cholesterol levels. Crataegus aronia exerts antioxidant activity and significantly improves the biochemical and hematological biomarkers in induced diabetic rats.

Background: Paracetamol or acetaminophen overdose leads to hepatotoxicity. This study evaluates the effect of Cordia lutea extract on paracetamol-induced hepatotoxicity in rats. Methods: Three different doses of dry fluid extract of C. lutea (200, 400 and 600 mg / Kg) were evaluated and compared with Silymarin 200 mg / Kg. Biochemical parameters such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), direct bilirubin, indirect bilirubin, total bilirubin, albumin, globulin and total proteins were evaluated, and histopathological changes in the liver were studied and evaluated. Results: C. lutea reduced the levels of ALT, AST, ALP and increases proteins significantly, although the reduction of bilirubin was not significant, the extract at 400 mg / Kg reduced the levels better than the extract at 600 mg / Kg. The histopathological evaluation suggested that C. lutea extract reduced paracetamol-induced liver necrosis. Conclusions: The extract of C. lutea has a marked hepatoprotective effect, significantly reducing the levels of ALT, AST and ALP, in addition to increasing the levels of albumin, globulin and total proteins, in Rattus norvegicus var. albinus. C. lutea extract is an excellent candidate for use in paracetamol-induced liver diseases.

Background: Artemisia absinthium L. is known for its antimalarial activity however, hepatoprotective activity of aqueous extracts has also been reported but, nephroprotective activity not yet evaluated. Objective: To evaluate the hepatoprotective and nephroprotective activities of A. absinthium against diclofenac-induced toxicity on rats. Materials and Methods: Three different doses of methanol and ethyl acetate extract of A. absinthium (50, 100 and 200 mg/kg/day) were evaluated and compared with silymarin 100 mg/kg. Rats received these doses for 5 days and on the 3rd and 4th day diclofenac (50 mg/kg i.p.) was administered 1 h after treatment. Animals were sacrificed 48 h after the last injection of diclofenac. Biochemical blood parameters like aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), urea and creatinine, and histopathologic changes of liver and kidney were studied and evaluated. Results: A. absinthium reduced the elevated blood levels of ALT, AST, ALP, urea and creatinine with the methanol extract to 200 mg/kg/day being more effective. The histopathologic evaluation suggested that A. absinthium decreased hepatic and renal necrosis induced by diclofenac. Conclusions: Hepatoprotective and nephroprotective activities of methanol and ethyl acetate extract of A. absinthium were demonstrated, being methanol extract to 200 mg/kg/day the most effective. This provides scientific support for the use of medicinal plants such as A. absinthium in the treatment of liver and kidney disorders.
