Sage essential oil is extracted from the leaves of the sage plant, which is a member of the mint family. It has a strong, herbaceous aroma that is both refreshing and invigorating. Sage essential oil has been used for centuries. Sage essential oil is generally safe for most people to use, but it is important to do a patch test before using it topically to make sure that you are not allergic. It is also important to avoid using sage essential oil during pregnancy and lactation. If you are considering using sage essential oil, be sure to talk to your doctor first, especially if you have any underlying health conditions.
