Aromatherapy 101
Humans have sought out plants for their healing benefits for millennia. Although the term “aromatherapy” was coined by a French chemist (René-Maurice Gattefossé) in 1928, the practice of aromatherapy has been utilized throughout Egypt, India, and China for thousands of years.
Aromatherapy is a compound word that consists of “aroma,” which means fragrance, and “therapy,” which means treatment.
Aromatherapy is a form of complementary and alternative medicine (CAM) that involves the therapeutic or medicinal use of essential oils.
Although aromatherapy has become associated with candles, soaps, lotions, and other products that are often made with fragrant or synthetic oils, actual aromatherapists only employ pure-grade essential oils that are derived from aromatic plants. These oils are extracted from the flowers, buds, leaves, stems, twigs, bark, wood, seeds, fruits, and roots of the plants. Although there are a variety of methods for how these oils are extracted, the most common method involves steam distillation. This process consists of bringing the plant material to a simmer and allowing the steam to travel through a tube into cold water. This process creates two different products: one that is water-based (which is used to make floral waters such as rose water) and one that is oil-based (which is the essential oil).
It has been well-established that there is a relationship between odors and emotions. Some of the best essential oils for reducing emotional states such as stress and anxiety include lavender, rose, orange, bergamot, lemon, sandalwood, clary sage, Roman chamomile, and geranium.
Out of these oils, lavender is by far the most popular and the most heavily researched. In fact, the French chemist who coined the term “aromatherapy” became interested in studying essential oils after burning his hand in a laboratory explosion. He applied lavender to the burn and was surprised that his hand healed without any scarring or infection. Modern research continues to validate lavender’s ability to heal wounds.
