Frankincense originates from a small scraggly tree indigenous to the Middle East, which is small with abundant pinnacle leaves. The flowers are white or pale pink. The resin begins as a milky-white sticky liquid that flows from the trunk of the tree when cut. The dried tears are collected, and the resin is then distilled, producing the precious oil. This essential oil has a warm and spicy, woody odor with a hint of citrus.
