Introduction: The plants has been a fertile source of revealing novel molecules discovered by sophisticated techniques for drug discovery. The present research was triggered by the increase in the use of Asparagus laricinus as home remedy, with a lot of studies done invitro on the plant evaluating possible toxic effects of the dried roots extracts using Sprague Dawley rats as animal models was needed. The objectives of the study was to investigate deviations effects in haematology and histology parameters, on the liver, kidneys and spleen tissues of animals exposed to aqueous and ethanolic extracts of Asparagus laricinus roots. Methods: Interfaculty Animal Ethics Committee approval was obtained from the Faculty of Health Sciences at the University of the Free State. All experimental work was performed in Animal Research Unit at the University of the Free State, Bloemfontein, South Africa. The supernatant of dried plants was filtered, and the ethanol removed completely under vacuum. The aqueous sample was lyophilized to obtain dried powdered material. The powdered plant material was dissolved in distilled water to prepare 2\%, 10\% and 20\% concentration. 54 Sprague Dawley rats (180g and 250g), both male and female, were divided into two groups of 24 and 30 rats for aqueous and ethanolic extracts respectively. The aqueous group was further divided into four subgroups of 6 rats which were exposed to 2\%, 10\% and 20\% extracts and the final group were controls (unexposed). The ethanolic group was divided into five subgroups of 6 rats which were exposed to increasing doses of 50, 100, 200 and 400mg/kg/day extracts and the last group were controls (unexposed). The aqueous extracts were administered to the three subgroups for eight weeks ad libitum while the control group was exposed to tap water. Ethanol extracts were administered daily over a period of two weeks through gavage and the control group was administered water through gavage as well. Blood samples were collected, animals were sacrificed, and organs/tissues excised for histological assessment. Results: Haematological tests were selected as indicators of the damage to the tissue of organs, including the liver, kidney, and spleen. Comparison of treatment groups (n=6) and controls (n=6) across all ethanol extracts showed significant differences in the starting median change in weight at the 200g/kg/day dosage, as well as the median termination weight at 400g/kg/day. There were no statistical differences between the treatment groups and controls with regard to the rest of haematological variables. Comparison of the controls (n=6) and treatment groups (n=6) revealed an average median change in weight of slightly above 50g over the entire eightweek period of experimentation with aqueous extracts. The Histological evaluation could not reveal any pathological changes in both the aqueous and ethanolic extracts across all levels of dosage. Discussion and conclusion: Haematological results could not show any patterns in abnormalities although we observed statistically significant results on few parameters. Histologically, no pathological changes were observed. In conclusion, we summarize that the toxicological evaluation of Asparagus laricinus extracts may be considered relatively free of toxicity when given orally, as it did not cause death, damage, or inflammation to the tissues, nor produced any remarkable haematological adverse effects in both the male and female Sprague Dawley rats.

Background: Medicinal plants are a reservoir of biologically active compounds with therapeutic properties that, over time, have been used for the treatment of various diseases. This study aims to evaluate the protective effect of the aqueous extract of the leaves of Salvia officinalis against cypermethrin-induced toxicity. Methods: 30 male rats weighing approximately 240 g were divided into equal six groups; the control group received tap water, the positive control received the aqueous extract of sage leaves (SLE) at a dose of (0.5g/kg bw), the groups treated with cypermethrin (Cyp1) at 8.33 mg/kg bw and (Cyp2) at 25 mg/kg bw, and the groups treated by cypermethrin combined with aqueous extract of sage SLE+Cyp1 (0.5g/kg bw+8.33 mg/kg bw) and SLE+Cyp2 (0.5g/kg bw+25 mg/kg bw) for four days/week. After 4 weeks of oral administration, epididymal seminal fluid was analyzed via the CASA system, in addition to the histological study testis and epididymis. Results: The obtained results showed a decrease in the absolute weight of the reproductive organs, with a significant decrease in sperm concentration, motility and speed in the cypermethrin-treated group compared to the control. Histological study of the testes and epididymis indicates an alteration in the stages of spermatogenesis in groups Cyp1 and Cyp2 compared to the control. However, the above-mentioned parameters were maintained almost normal in the groups that received the aqueous extract of sage with both doses of cypermethrin. Conclusion: it can be demonstrated that SLE has been shown to protect rats from cypermethrin-induced reprotoxicity.
