Abstract

---

In Kenya various plant extracts are widely used as folklore remedies for various ailments including malaria etc. However, use of these traditional remedies poses a risk to the users due to the scarcity of data on their safety including their teratogenic potential. Hence this study evaluated the teratogenic and sub-acute toxic effects of methanol: dichloromethane extract of Toddalia asiatica in animal mice. In the study, young female mice aged between 6-7weeks were mated with mature males and conception confirmed using vaginal plug, maternal weight and breast enlargement.  Administration of the dosed of the plant extract and controls was done from day 6 through 15 of gestation. The mice were euthanized on the 19^th day of gestation. The weight of the gravid uterus, pups, number of pups and gross examination to identify any physical abnormalities was done. In the toxicity study male mice aged between 6-7 weeks received oral administration of high doses of plant extract and the control daily for 28 days. On the 29^th day animals were sacrificed, cardiac puncture conducted and collected blood for hematology and biochemistry analysis. The data obtained was analyzed using one way ANOVA followed by Tukey as the post hoc test. Statistical significance was set p < 0.05. The extracts caused significant reduction (p
