Rosemary a natural healer.
Here is what I found out.
Rosemary essential oil is used to alleviate headaches and migraines, and as a general pain reliever for muscles. It can be used as a hear tonic to help normalize blood pressure. It is also used in vaporizer to clear the head and chest and to get rid of chest infections.
Rosemary is advised not to be used during pregnancy or if a person suffers from epilepsy.
