Aromatherapy uses natural extracts from flowers, herbs, trees and other plants to promote physical and emotional wellbeing. It’s usually used to help with symptoms like anxiety, stress and pain.
You breathe in the aroma from essential oils or put them on your skin during an aromatherapy massage. You can also use them in a vaporiser or spray bottle.
Essential oils
The oils of many plants are thought to have beneficial properties. They are concentrated plant extracts that smell strongly and contain powerful chemical compounds.
When inhaled, essential oil scents travel from the nose to the limbic system of the brain where they affect emotion and can have a physical impact on bodily systems. They can be used in aromatherapy to help relieve stress, lift mood and more.
An essential oil’s composition varies depending on the plant, climate, rainfall and geographical location. It can also be influenced by the time of harvesting, distillation and processing.
Because essential oils are highly concentrated, it is important to dilute them before applying them to the skin or using them in a diffuser. The National Association for Holistic Aromatherapy offers dilution guidelines. Also, because of the strong effects that some oils can have, it is important to consult with a medical professional before adding any essential oil into your daily routine, especially if you’re taking medications or are pregnant or breastfeeding.
Carrier oils
Carrier oils are a vital ingredient in aromatherapy because they are used to dilute essential oils before they are applied to the skin or hair. They are derived from the fatty portions of plants such as seeds, nuts and kernels. They can be cold-pressed or solvent extracted. They are not as volatile as essential oils and do not go rancid.
The type of carrier oil you choose depends on the intention behind your use. For example, if you are using it in a massage, you might prefer one that has good slip and slides easily. The odour of the oil is another consideration, as well as how quickly it absorbs into the skin and leaves a non-greasy feeling.
Some carrier oils are best stored in dark glass, as they can be prone to rancidity. Others can be refrigerated to prolong their shelf life, but this may affect some of the oil’s significant, delicate constituents. For this reason, most aromatherapists prefer to purchase their carrier oils in small bottles that will be used up well before the oil has a chance to go bad.
Techniques
Aromatherapy is the practice of using natural plant extracts in different ways to promote emotional, physical and spiritual health. It involves the use of essential oils and carrier oils. It also incorporates ancient herbal, medical, religious and cultural philosophies and techniques.
Carrier oils are used to dilute essential oils before they’re applied to the skin. They’re made from cold-pressed vegetable oils, such as sunflower (Helianthus annuus), jojoba (Simmondsia chinensis), and grapeseed (Vitis vinifera). They may be mixed with essential oils or infused with herbs like St. John’s wort (Hypericum perforatum).
While it’s extremely unlikely that smells can have any direct physiological effects (with the exception of menthol and eucalyptus) there’s some good research supporting the idea that pleasant scents can improve mood and decrease stress. There’s also some evidence that aromatherapy can help people sleep better, so it’s worth a try if you’re struggling to get restful nights. Just make sure to choose quality tools, use safe techniques and learn from experienced instructors.
Safety
Generally speaking, the use of essential oils in aromatherapy is considered complementary and alternative medicine (CAM). Unlike drugs that are regulated by a government agency, essential oil products have not undergone rigorous scientific testing. However, a number of studies indicate that some oils have a physiological effect when inhaled or applied topically to the skin.
It is important to remember that essential oils are highly concentrated and may cause an adverse reaction if not properly administered. Ensure that the room where you are applying or diffusing is well ventilated, especially if there are pets, children or people with serious health conditions such as asthma.
Never put undiluted essential oil directly into your mouth. This can damage the lining of your throat and stomach. If you think that you or someone else has swallowed an essential oil, call the Victorian Poisons Information Centre on 13 11 26 (seven days a week, 24 hours a day) for immediate advice.
