Abstract
The damaging effects of heavy metal exposure on vital organs like the heart, liver, kidneys, and brain can be lowered by natural compounds' anti-inflammatory and anti-oxidant capacity. In the current investigation, the protective potential of savory(Saturejahortensis)essential oil (EO) against lead acetate-induced multi-organ damage in rats was evaluated. Thirty female Wister Albino rats were divided into the following groups: normal, positive control given lead acetate without concomitant treatment, reference given ethylene-diamine-tetra-acetic acid and groups treated with savory EO (0.5 and 1 ml/rat), treatments were administered concomitantly with lead acetate for ten successive days. Electrocardiogram (ECG), open field, and rota-rod tests for evaluation of behaviour, as well as TNF-α, R-GSH & MDA were measured in brain and liver homogenates respectively, CRP, liver, kidney, and heart function tests, were measured in serum. Histopathology of vital organs was conducted at the end of the experiment.A high dose of savory EO, significantly improved the cardiac electrophysiology, psychological state, and locomotor activity of rats; moreover, it lowered inflammatory, oxidative biomarkers, liver, kidney, and cardiac function tests of the rats. Savory EO protects vital organs against heavy metal damage with the superiority of the high dose.
