Not all essential oils in the supermarket are actually natural. If the words "naturally derived" are on the bottle, that means the molecular structure of the oil was simply derived from a flower or plant in a laboratory. In fact, the oil may be 100% synthetic. Look for USDA certified organic oils, or opt for scents like peppermint and rosemary, which are plentiful ingredients that are almost always actually natural and not "naturally derived."
