Medicinal Plants as Protective Modulators of Pesticide-induced Toxicity in Animals: A Review

Abstract

The widespread use of pesticides in modern agriculture poses significant threats to animal health, livestock productivity and environmental safety. Exposure to these chemicals has been associated with oxidative stress, DNA damage and disruption of endocrine, immune and nervous systems. In recent years, increasing attention has been directed toward natural interventions to mitigate pesticide-induced toxicity, particularly in veterinary and livestock systems. This review evaluates existing literature on the ameliorative potential of medicinal plants and their bioactive phytochemicals against pesticide-induced toxicity. Relevant studies involving multiple animal models, including rodents, poultry (chicken embryos), cattle feed systems and aquatic species, were analyzed. Emphasis was placed on phytochemicals such as flavonoids (quercetin), polyphenols (curcumin), alkaloids and other phenolic compounds and their mechanisms of action in counteracting toxic effects. The findings indicate that medicinal plants and their bioactive constituents exhibit significant protective effects against pesticide-induced toxicity. These effects are primarily mediated through restoration of antioxidant defense systems, including increased activity of superoxide dismutase, glutathione peroxidase and catalase, along with reduction in lipid peroxidation. Additional benefits include stabilization of cellular membranes, modulation of apoptotic pathways and prevention of histopathological damage in vital organs. However, most studies are limited to controlled laboratory conditions, with insufficient translation to clinical and field applications in livestock. Key challenges identified include issues related to dose standardization, bioavailability and species-specific responses.
