Aromatherapy is a type of alternative medicine involving the use of essential oils that has been around for about 6000 years. It is a holistic therapy which means that aromatherapy practitioners consider not just your physical symptoms, but also mental, spiritual and emotional factors. Holistic therapy recognizes that these factors are essential to take into account as they all have a great influence over your health.

There are three main ways that the essential oils used in aromatherapy enter your body:

* through your skin
* through olfaction – your sense of smell
* through your lungs

The Skin
Using essential oils in massage is the most common use of aromatherapy. The massage oil is made from a carrier oil with a few drops of essential oils added, this allows the essential oils to be absorbed into the skin. Applying heat will increase the rate at which the oils are taken in. The massage itself will produce a bit of heat, and covering the area with towels or blankets or a heated wheat bag is also common.

Once the essential oils are absorbed into the skin they work their way into the underlying tissue thereby affecting the nerves, organs and blood stream.

Here’s a quick and easy experiment to prove that essential oils really can enter your body through your skin. Cut a clove of garlic in half and rub the liquid (garlic essential oil) from the cut end on the bottom of your foot. See how long it takes before you can taste garlic on your breath (usually about 15-20 minutes).

The Sense of Smell (Olfaction)
The olfactory receptors, which are called chemoreceptors, are nerve endings embedded deep within your nasal passages. Fragrance chemicals in the air are inhaled and dissolve once they hit the fluid lining in your nasal passages. This allows the chemoreceptors to pick them up and send the ‘chemical message’ to the brain.

These chemical messages are sent first to the frontal lobe of the brain where the smell is analyzed, and secondly to the limbic system and autonomous nervous system. This is where emotional and physical responses to the fragrance are created. For instance, you might feel calm or sleepy, or you might sneeze. You might also be reminded of something in your past, and this experience will have an emotional response attached to it.

Some essential oils actively mimic neurotransmitters which have a powerful ability to alter mood. These can be helpful for conditions such as stress and depression.

The Lungs
Inhaling essential oils is the fastest way to get them into your bloodstream where they can start working. This is because the lungs are very efficient at absorbing oxygen, and vaporized essential oils that you breathe in. Since your respiratory system is designed to get oxygen into your bloodstream, when you inhale the fragrance of essential oils, they too are carried quickly into your bloodstream.

Some Benefits of Essential Oils
In France, where modern day aromatherapy originated, it’s a part of mainstream medicine in the control of infections because of the strong antibacterial, antiseptic, antiviral and antifungal properties of many essential oils.

All essential oils are antiseptic to some degree. However, a few of the more powerful antiseptics are lavender, thyme, clove, cinnamon, tea tree, manuka and oregano.

Essential oils are extremely beneficial in skin care. The ancient Egyptians, who invented cosmetology, used essential oils in skin care around 5000 years ago.

A study in Japan showed that lemon, vaporized in a room, reduced typing errors by 54%. Lemon is well known for it’s antiseptic and antimicrobial properties which would also make it beneficial throughout office buildings.

These are just a few of the many uses of essential oils in aromatherapy. But there is also an important aspect of aromatherapy that doesn’t get mentioned often – the pleasure aspect. Using essential oils is fun, even if you aren’t a qualified aromatherapist. Have some fun discovering which fragrances you enjoy, they are bound to have a beneficial effect even if you just use a few drops in your bath water.
