This 2019 review describes the phytochemical profile, ethnopharmacological uses of rosemary essential oils, some biological activities emphasizing its anti-inflammatory potential and possible mechanisms of action involved. 150 chemical compounds were identified in EORO samples, more frequently reported molecules were 1,8-cineole, α-pinene, and camphor. Its antioxidant activity also aids by preventing injury caused by the reactive species of inflammation; its smooth muscle relaxant activity contributes to ameliorating airway inflammatory diseases. Lastly, toxicity assessments indicate low toxicity to EORO.
