Oil of Rosemary (Rosmarinus Officinalis) is one of the best aromatic oils due to its incredible antioxidant properties. This evergreen plant is called Rosmarinus Officinalis in Latin, and it means “the dew of the sea.” The oil is a steam distillation from the leaves and the flowers of rosemary.


Rosemary plant is native to the Mediterranean; you can see this plant thrive just about anywhere in countries like Turkey, Spain, France, Italy, and Portugal. 


It’s a member of the Lamiaceae plant, just as Peppermint. This plant has got some beautiful pink and white flowers and can stand long periods without water. It’s an herb that’s hard to start from the seed, but once it’s established, it can live up to 30 years. Usually, it reaches around a 1.5-meter height, and in warm climates, it blooms almost all the time.
