Aromatherapy, or essential oil therapy, refers to a variety of conventional, alternative or complementary treatments using essential oils and other compounds of the aromatic plants.
Essential oils have been used for almost 6,000 years, in order to improve the health or mood of an person. The NAHA describes aromatherapy as “the medical application or medicinal use of aromatic substances (essential oils) for holistic healing.”
In 1997, the International Standards Organization ( ISO) defined an essential oil as a “product obtained from vegetable raw material, either through distillation with water or steam, or through a mechanical process from the epicarp of citrus fruit, or through dry distillation.”
A number of essential oils have been shown to have varying degrees of antimicrobial activity, with antiviral, nematicidal, antifungal, insecticidal and antioxidant properties. Uses for aromatherapy include acupuncture, topical applications, and inhalation.
However, users should be aware that “natural” products are also chemicals, and if used in the wrong way, they can be hazardous. When using essential oils it is important to follow a trained professional’s advice.
Aromatherapy is commonly used as a topical treatment or by inhalation.
Inhalation: The oils evaporate into the air using, for example, a diffuser bottle, mist, or oil droplets, or inhaled in a steam bath.
Aromatherapy oils can provide respiratory disinfection, decongestant and psychological benefits besides having a good scent.
The inhalation of essential oils stimulates the olfactory system, the part of the brain that is connected to smell including the nose and brain.
Molecules entering the nose or mouth travel into the lungs, and from there into to other parts of the body.
We affect the limbic system when the molecules enter the brain, which is related to the emotions, heart rate , blood pressure, breathing, memory, stress, and hormone balance. In this way essential oils can affect the body in a subtle yet holistic way.
Topical applications: The skin absorbs massage oils and bath and skin care products. Massaging the region where the oil is to be added will improve circulation and the absorption. Others claim that areas rich in sweat glands and hair follicles, such as the head or the palms of the hand, will more easily absorb the oils.
Essential oils are never applied directly to the skin. They must always be diluted with a carrier oil. Usually, a few drops of essential oil to an ounce of carrier oil is the concentration. Most common carrier oils are sweet almond oil or olive oil.
To do an allergy test:
Dilute the essential oil in a carrier oil at twice the concentration you plan to use
Rub the mixture into an area the size of a quarter on the inside of the forearm
When no allergic reaction occurs within 24 to 48 hours, then use should be healthy.
Some people have reported developing allergies to essential oils many times before after using them. If a new allergic response appears, the individual should immediately stop using it and avoid the smell of it.
Use 3 to 6 drops of essential oil per ounce of carrier to achieve a dilution of 0.5 to 1 per cent. Add 30 drops to one ounce of carrier for a 5 per cent dilution.
Adults are usually considered healthy at a maximum concentration of 5 per cent.
Aromatherapy is a complementary therapy. It does not provide a cure for diseases, rashes or illnesses, but it can support conventional treatment of various conditions.
Many forms of psoriasis can find relief with aromatherapy, but the use and use should be recommended by a health care professional.
Peppermint oil may benefit from digestive problems but it should not be swallowed.
Clove oil can relieve tooth ache and mouth sores but this, too, should only be applied topically and should not be swallowed.
Supporters believe that these and a large variety of other complaints respond well to aromatherapy, but empirical evidence supports not all uses.
