Carrier oils, also referred to as base oils or vegetable oils, are used to dilute essential oils, and absolutes before applying to the skin. They ’carry’ the essential oil onto the skin. Different carrier oils offer different properties and the choice of carrier oil can depend on the therapeutic benefit being sought.
Essential oils are made from flowers, herbs and tree parts, like bark, roots, resins and petals. The cells that give a plant its fragrant smell are its “essence.” When an essence is extracted from a plant, it becomes an essential oil. It takes a lot of plant material to make essential oils. More than 200 pounds of lavender flowers are used to make just 1 pound of lavender essential oil.
