Rosemary Essential Oil: Benefits, Uses, and Precautions
Rosemary (Rosmarinus officinalis) is a perennial herb native to the Mediterranean region. Known for its needle-like leaves and clusters of small flowers that range from white and pink to blue and purple, rosemary is hardy, drought-tolerant, and naturally pest-resistant.
It takes approximately 200 pounds of rosemary leaves to produce just one quart of essential oil, making this oil both precious and highly valued in natural health and beauty care.
