Rosemary Oil

Rosemary’s essential oil — which holds the plant’s core components, or essence — is extracted and sold in small bottles. Despite its name, it is not a true oil, as it doesn’t contain fat. Rosemary and other essential oils are readily absorbed into your bloodstream when you apply them to your skin. ... It’s generally advised to dilute essential oils with a neutral carrier oil, such as jojoba oil. This helps prevent potential irritation of your skin and premature evaporation of the oil. Though most of this research is preliminary, studies note that this essential oil may boost your health by improving mental focus and memory, fighting hair loss, relieving pain and inflammation, repelling certain insects and easing stress.
