But aromatherapy is more than just a '90s-style novelty. The practice of using aromatic essential oils for psychological and physical well-being dates back more than 4,000 years to medicinal practices in Egypt and India.

The term "aromatherapy" was coined in 1937 by French cosmetic chemist R.M. Gattefosse, who discovered the benefits of essential oil after burning his hand in a laboratory accident. Gattefosse immersed his hand into the nearest available cool liquid: a vat of lavender oil. The near miraculous soothing of his pain and rapid healing spurred him to dedicate his life to the study of aromatic plants and their therapeutic effects.

How it Works

For those who turn their noses up at this most seemingly-subtle of senses, keep in mind that the perception of smell is 10,000 times more sensitive than the sense of taste. "The sense of smell is the sense of the imagination," noted French philosopher Jean-Jacques Rousseau; this emotional connection lies at the heart of aromatherapy.

Aromas are transmitted rapidly from olfactory cells in the nose to the limbic system in the brain which perceives and responds to emotion, pleasure and memory. Scents trigger the limbic system to release neurochemicals which influence mood. Well-known neurochemicals like endorphins and serotonin help create a sense of well-being.

When you inhale essential oils, some of the molecules travel to the lungs, where they proceed to enter the bloodstream and circulate throughout the body.

Oils applied to the skin are absorbed into the bloodstream as well. Because they are oil/fat soluble, essential oils are highly absorbed by the body, where they circulate for anywhere from 20 minutes to 24 hours and are eventually eliminated through sweat and other bodily secretions.

Plant Power

Essential oils are extremely potent and volatile: approximately 75 to 100 times more concentrated than dried herbs.

Most essential oils are steam distilled from herbs, flowers and plants. Others are cold expressed from the rind of the fruit, which produces the purest essential oils because no heat or chemical treatment is involved.

The components of various oils are beneficial for a wide variety of beauty and hygiene conditions. Some of the more indispensable essential oils include:

Chamomile (anthemis nobilis): soothing properties for sensitive and inflamed skin; calming, balancing and relaxing.

Clary Sage (salvia sclarea): warming, female balancing herb used for PMS; calms anxiety, tension and stress; also used as a muscle relaxant for aches and pains.

Eucalyptus (eucalyptus globulus): antibacterial; fresh, herbal menthol aroma; widely used as an inhalant for colds, coughs and congestion; excellent for massaging tired or sore muscles.

Geranium (pelargonium graveolens): one of the best all-around tonic oils for mind and body; soothes nervous tension and mood swings; balances female hormones and PMS; gently astringent and antiseptic, it improves general tone and texture of skin.

Jasmine (jasminum grandiflorum): a warm, rich, sensual floral scent used historically as an aphrodisiac; moisturizing for dry/mature skin.

Lemon (citrus limonum): refreshing and invigorating; eases tension and depression; useful for oily skin and treatment of acne.

Peppermint (mentha piperita): cool, menthol, invigorating stimulant; cleans and purifies the skin.

Rosemary (rosmarinus officinalis): stimulating and uplifting; purifying and cleansing for all skin types; warm and penetrating for massage to ease muscular aches and pains.

Tea Tree (melaleuca alternifolia): an antiseptic from the leaves of the Australian tea tree; antifungal, antibacterial and antiviral; excellent for skin irritations like cold sores, insect bites and acne.

Ylang Ylang (cananga odorata): enticing and sensual; helps alleviate anger, stress, insomnia and hypertension; helps balance the skin's sebaceous secretions.

Oil Well

Essential oils can be utilized in a variety of ways: in electric or candle-based diffusers, to spread the aroma through a room; in sachets and air fresheners; added to shampoos and lotions; or diluted and applied to pulse points like the temples, on neck or on wrists. Undiluted essential oils should never be applied to the skin. First mix them with carrier oils: pure vegetable oils such as sweet almond oil, grapeseed oil and apricot kernel oil. Use a general guideline of six to 18 drops of essential oil per one ounce of vegetable oil. Blended, diluted oils are also available which can be used directly on your skin.

Pond's Aromatherapy Capsules come in four scents: Happy, which is fruity and floral; Romantic,with musk and vanilla; Relaxing, a floral and woodsy aroma; and Energizing, with fresh citrus and bright floral scents.

Sarah Michaels offers four essential oil blends: Sensual Jasmine, Soothing Lavender, Refreshing Citrus and Invigorating Peppermint.
