Conium maculatum L. (C.M) is a poisonous plant species particularly for animals including mainly cattle. Even though it is known for its toxicity, clinically has significance due to sedative, antispasmodic and anti-inflammatory properties. For the first time present this study designed to investigate the therapeutic and fatal doses of C.M extract in gestated albino Wistar rats. To evaluate the therapeutic and toxic levels of different concentrations of C.M extract in gestation and foetal development of adult albino Wistar rats. C.M extract at different doses of 10 mg/kg, 20 mg/kg, 30 mg/kg, 40 mg/kg and 50 mg/kg was orally administered to rats in the entire gestation period. The changes in morphology of mother and siblings, foetal formation, pups birth rate, pups survival rate and AchE levels, MAO levels, and Dopamine levels were measured to ensure the nonlethal dose of the extract. In the treated mother rat group, 50 mg/kg concentration caused death and 20 mg/kg concentration of extract showed good therapeutic values. Birth rate, survival rate, dopamine, MAO levels, SOD, AchE and protein levels decreased upon increasing concentration, whereas LPO and MAO levels increased in mother and sibling rats. Histopathological studies showed that 20 mg/kg concentration of extract showed no damage in neuron cells with maximum increase in number. Our findings suggests that C.M 50 mg/kg dose is a toxic concentration in the mother group whereas 40 mg/kg dose in sibling rats by increasing the levels free radicals, decreasing AchE neurotransmitters level, and increasing MAO levels.
