Aromatherapy: Benefits, History & How It Works

Aromatherapy is a method of using plant extracts, or essential oils, to maintain holistic well-being. Scent is believed by many to stimulate healing on physical, emotional and spiritual levels.

History

• Though the exact date of its origin is inconclusive, references to aromatherapy can be found in the Old Testament and in the tombs of ancient Egypt. The term "aroma-therapie" was coined by French scientist Rene Maurice Gattefosse in 1928, and literally means "healing through aroma."

Origins

• Aromatherapy oils are separated from plant materials through processes known as distillation or cold-pressing. The distinct source of oil depends on the plant; chamomile oil, for example, is extracted from flowers, while basil oil is extracted from leaves. The result is a concentrated oil typically diluted in a "carrier" (neutral) oil before use.

Theory

• Chemical components of each oil have different effects on the body and brain. Esters, found in chamomile and lavender, are anti-fungal and sedating. Cinnamon, clove, and basil oils all contain Ethers, which are diuretic and antiseptic.

Function

• When the body inhales or absorbs these constituents, a signal is received by the pituitary and hypothalamus glands of the brain. They decide to relax or stimulate the nervous system accordingly.

Practice

• Aromatherapists use this criteria, among others, to choose appropriate oils. Though its efficacy lacks sufficient scientific evidence, many personal reports support its extolled benefits.
