The Essential Oil Profiles area details over 90 essential oils. Absolutes, CO2s and Hydrosols are also commonly utilized in aromatherapy. Although essential oils, CO2 extracts and absolutes are distilled in different manners, the term essential oil is sometimes used in writing as a blanket term to include CO2s and absolutes.
In addition to essential oils, aromatherapy encourages the use of other complementary natural ingredients including cold pressed vegetable oils, jojoba (a liquid wax), hydrosols, herbs, milk powders, sea salts, sugars (an exfoliant), clays and muds.
Products that include synthetic ingredients are frowned upon in holistic aromatherapy. It is important to note that perfume oils also known as fragrance oils (and usually listed as "fragrance" on an ingredient label) are not the same as essential oils. Fragrance oils and perfume oils contain synthetic chemicals and do not provide the therapeutic benefits of essential oils.
Buyer Beware
The United States does not regulate the use of the word aromatherapy" on product packaging, labeling or in product advertising, so any product can be marketed as a product suitable for aromatherapy. There are quite a few products on the market that contain unnatural ingredients including fragrance oils and claim to be aromatherapeutic. It's important to look at the ingredient label when seeking true aromatherapy products.
Also, use caution with marketing claims that state a product is "Made With Essential Oils" or "Made With Natural Ingredients." Claims like these do not state that the product is only made with the ingredient(s) specified. Such products may contain heavy proportions of synthetic fragrance oils and only contain a minute quantity of essential oil to simply be able to profess the "Made With Essential Oils" claim.
