Essential oils are made from flower, herb, and tree parts, like bark, roots, peels, 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 product to make essential oils. More than 200 pounds of lavender flowers are used to make just 1 pound of lavender essential oil.
Lemon, chamomile, lavender, cedarwood, and bergamot are a few of the essential oils used regularly in aromatherapy.
