History of Aromatherapy

The absolute & essential oils used in Aromatherapy are distilled from plants that
come from every continent on the globe. Each essential oil comes from a specific
plant. Each plant shares a vibrant aromatic energy.

Aromatherapy is the use of pure essential and absolute oils. Essential oils are complex, highly
fragrant and volatile substances, with varying degrees of complexity, fragrance, and volatility.
They are the most potent and concentrated extracts of various parts of flowers, fruits, leaves,
spices, roots, and woods. The plant's essence molecules are approximately 75-100 times more
concentrated as an essential oil than in the dried plant.

While in the plant, the essence molecules play a key role in the biochemistry of the plant --
they are located between the cells of the plant and these molecules act as regulators and
messengers. By giving the plant its aromatic essence, they are also thought to give the plant its
"life force". They also protect the plant from parasites and disease, and play an important role
in fertilization and assist the plant's adaptation to its environment.

To obtain essential oils the aromatic essence molecules of the plant must be captured by
using a technical distillation or extraction method. In earlier times, the art of distillation was
held in the hands of the few and was considered to be an alchemical transformation of spirit,
a bridge between the two realms.

The term "essential oil" is used somewhat loosely as it is often applied to all aromatic
products such as essence oils, absolutes, resinoids, and concretes. In Aromatherapy, the most
common method of extraction is steam distillation. However, cold expression is used for citrus
oils, and a method of solvent extraction for absolutes, concretes and resinoids. The newest
technological process of extraction is the hypercritical carbon dioxide method: in part due to
high cost, it is not as commonly available.
