Although personal preference and experience can influence your choice where alternatives are offered, we do indicate biochemical specificity where it is an important factor. Botanical names are listed indicating genus, species and variety or chemotype (where applicable) as well as the recognised abbreviation for the botanist who first identified the particular plant. Current preferred origins are stated correctly as at the time of publication but can vary over the course of a year, dependent on growing conditions and other factors. Oils that are particularly rare or subject to seasonal shortage, including special extractions, are featured in our separate Rare & Exotic Oils section.

Pure essential oils should only be used under professional guidance from a qualified aromatherapist. Under proper storage (in tightly sealed dark glass or aluminium containers away from extremes of temperature and sunlight) the majority of essential oils should have a ‘life’of 2 years from distillation. In the case of citrus oils, we would suggest that this be reduced to 6-9 months. All orders are supplied with an Essential Oil Safety Sheet.
