Certain essential oils, like hot oils, need to be used in a certain way (e.g., oregano which is hot to the touch). The National Association for Holistic Aromatherapy has put together an empirically based resource guide for essential oil use and safety. Most oils can be used daily in various ways. At Day by Day Counseling Center, we always provide the highest quality products, and clearly label all products with accurate ingredient information and quality. Compare the Apothecary ingredients to those of other brands. Skin Deep developed an up-to-date database to know how each ingredient affects you, and how some ingredients can promote health instead of disease.
