Carvacrol Coadministration Ameliorates Lambda-Cyhalothrin-Induced Peripheral Neuropathy in Rats: Behavioral and Molecular Evidence. [PDF]
J Biochem Mol ToxicolThis study investigates the peripheral neuropathy induced by the pesticide Lambda‐cyhalothrin (CYH) and how carvacrol (CRV) treatment reduces these effects. CYH causes neurological disorders, oxidative stress, and inflammation, while CRV reverses these harmful effects with its antioxidant, anti‐inflammatory, and antiapoptotic properties.
