When creating Aromatherapy blends, essential oils are used. This gives blends therapeutic properties as well as a scent. Aroma therapists usually blend oils using a similar method to that used to create perfumes. Normally only three or four essential oils are used in a blend and these will be comprised of at least one each of top, middle and base notes. This can make a blend smell more pleasant or balanced but it also means that the blend will have a synergy since different oils can be combined to create a blend with more therapeutic properties than that of a single essential oil. Blends can be made to help with a variety of symptoms or problems because of this.
Essential oils can be divided into top, middle and base notes although there is still debate over some oils as to which category they belong in.
