Rosemary (Rosmarinus officinalis) is far more than a flavorful culinary herb—it’s a powerhouse of natural wellness. Modern research confirms what herbalists have long known: rosemary essential oil offers a wide range of potential benefits, from supporting immunity and easing pain to promoting mental focus, boosting hair, and protecting your cells from damage.

 

The History of Rosemary

Rosemary has been valued since ancient times across the Mediterranean. Its name, meaning “dew of the sea,” reflects its coastal origins. Ancient Greeks and Romans used it to enhance memory and in ceremonial rituals. In the Middle Ages, rosemary became a symbol of remembrance and was burned in churches for purification. Today, its essential oil is celebrated globally for its potent therapeutic properties, bridging time-honored tradition with modern science.¹
