To best learn how to make effective aromatherapy blends it will help to understand the history behind the perfume industry. In the early 19th century, the Englishman George William Septimus Piesse discovered a way to classify scents. Similar to music he used "top notes", "middle notes" and "base notes". He called this an "odophone".
Middle notes are revealed once the top notes evaporate and form the character of a blend. These middle notes are generally floral, herbal and light woody, and spicy scents such as Geranium, Juniper and Black Pepper.
The heavier and richer base notes are usually woods, resins, and spices such as Cedarwood, Benzoin and Cinnamon. These base notes are warming and tend to hang around the longest and they round off a good blend.
Ideally all aromatherapy blends should contain all three notes, to keep the blend in harmony and 'in tune'! That is the secret behind essential oil blends.
