ENFLEURAGE

Enfleurage is obtained by placing a layer of fresh flowers on a thin layer of fat (usually lard), or on an oil-soaked cloth. Every day, the flowers are replaced with fresh ones until the right degree of concentration is obtained. Since this method does not allow the separation of essential oils, the final product will be used in creams, massage oils and bath oils.

STEAM DISTILLATION

Steam distillation is the most common way of extracting essential oils from the plant. The steam is forced into a vat of plant material where the little pouches are broken releasing the essential oils. After a cooling phase, the oils are finally collected. This is the most popular method of natural extraction.

EXPRESSION

When essential oils are squeezed or cold-pressed from the fruit, this method is called expression. This is the method utilized to extract essential oils from citrus fruits, since their oils are present in the skin of the fruit and the steam distillation process would alter and damage their composition.

SOLVENT EXTRACTION

Given the increasing market demand for essential oils, solvent extraction is now often utilized. It is important to realize that this method DOES NOT PRODUCE PURE ESSENTIAL OILS. The outcome is a highly scented concentrate mainly used in the perfume and food industry. The plants are immersed in a solvent (acetone or a petroleum byproduct) and the separation is obtained chemically. This method is used widely for neroli, rose, tuberoses, jasmine, honeysuckle, and others. These so called ‘concretes’ and ‘absolutes’ should NOT be used for aromatherapy.

CONCLUSION

Distillation and expression are the only methods of extraction that produce true essential oils. All other methods produce aromatic products primarily utilized in the perfume industry, herbal medicine and skin care.
