Abstract

Recent studies have shown that essential oils (EOs) extracted from medicinal and aromatic plants have herbicidal and/or insecticidal properties, helping to mitigate the toxicity experienced by living organisms exposed to pesticides. Moreover, the primary compounds isolated from these EOs also have the potential to reduce pesticide-induced damage. The present work aimed to evaluate the protective effects of Thymus numidicus (TNEO) and Lavandula stoechas (LSEO) against Deltamethrin-induced toxicity in female rabbits. The results obtained by GC/MS analysis showed that monoterpenes and oxygenated monoterpenes were the main components of the EOs extracted from the aerial parts of Thymus numidicus and Lavandula stoechas. The use of the pesticide Deltamethrin caused significant damage to the liver and kidneys (p < 0.05), together with blood disorders, signs of restlessness and tremors. However, females treated with TNEO showed better tolerance than the group treated with LSEO. The combination of both oils showed more pronounced protective effects. This suggests a potential synergistic effect in reducing deltamethrin-induced toxicity.
