What is rosemary essential oil and where does it come from
Rosemary essential oil comes from a woody evergreen shrub native to the Mediterranean region. The plant thrives in sunny, dry climates and has been used for centuries as both a culinary and medicinal herb.
The oil is distilled from the leaves and flowering tops, where aromatic compounds naturally concentrate to protect the plant and give it its strong, fresh scent.
How rosemary essential oil is extracted
