Rosemary Essential Oil: Health Benefits And Ways To Use It

Rosemary, like other herbs, has been a part of the kitchen and medicine shelf for thousands of years. Used for its flavor and as a cure even today, rosemary has gained popularity in its oil form, too!

The rosemary essential oil is extracted from the herb through steam-distillation. In this method, the herb is allowed to boil with water. Once the steam and oils are collected, they are separated to form the essential oil. The oil is equally beneficial as it retains rosemary’s anti-inflammatory, anti-fungal, antibacterial, and antiseptic properties, which give it its health benefits.


Take a look at these benefits of rosemary essential oil and how you can use it.
