Abstract: Fluoride is toxic to neuronal development and its excessive intake during pregnancy cause adverse effects on neonatal development. The present study examined the presence of oxidative stress during maternal exposure of fluoride and the therapeutic strategy of Aloe vera, Curcuma longa and Ocimum sanctum extracts in functional prevention of fluoride led oxidative stress. The pregnant Wistar rats were exposed to 100 ppm fluoride in drinking water and pups born to them were supplemented with phytoextracts daily. On 21st postpartum day, the pups were sacrificed to analyse fluoride and oxidative stress markers. Fluoride exposure significantly increased its accumulation, lipid peroxidation and decreased the activities of catalase, superoxide dismutase, glutathione peroxidase, glutathione-S-transferase and glutathione levels in discrete regions of the central nervous system (CNS) of pups indicating oxidative stress and inhibited antioxidant defense. The results implied the vulnerability of developing CNS to fluoride toxicity. On phytoextract supplementation, the oxidant devastation was suppressed by regaining antioxidant homeostasis near normal level proving efficacy and therapeutic strategy. Among the phytoextracts supplemented the Ocimum sanctum is found to be more effective.
