Toxicity of the pesticide carbofuran (CF) can be alleviated by curcumin, if not for its poor bioavailability. Hence, we investigated the effect of a bioavailable curcumin-galactomannan complex (CGM) on CF-induced neurotoxicity in rats in comparison to that of unformulated standard curcumin (CS). The CF (5 mg/kg b.wt/day) treatment for 90 days produced chronicity model which were treated with either CS or CGM (100 mg/kg b.wt and 250 mg/kg b.wt/day) for another 30 days. Improvement in CF-induced behaviour was evident in endurance, motor co-ordination and pain response on both CS (p < 0.01) and CGM (p < 0.001) supplementation. Amelioration of CF-induced toxicity parameters, oxidative stress, and mitochondrial dysfunction on CS (p < 0.01) and CGM (p < 0.001) supplementation was further confirmed by histopathology of brain and liver tissues. But, CGM was more effective in mitigating CF toxicity, with results comparable to that of normal. Hence, CGM might be superior in toxicity management against CF.
