There is an immense amount of studies exploring the concerns that essential oils are highly concentrated and can irritate the skin when used in undiluted form. Therefore, they are normally diluted with a carrier oil for topical application, such as jojoba oil, olive oil, or coconut oil. Phototoxic reactions may occur with citrus peel oils such as lemon or lime. Also, many essential oils have chemical components that are sensitisers (meaning that they will, after a number of uses, cause reactions on the skin, and more so in the rest of the body). Chemical composition of essential oils could be affected by herbicides if the original plants are cultivated versus wild-harvested. Some oils can be toxic to some domestic animals, with cats being particularly prone.
Hey Karen, There’s so much information on essential oils and much of it comes from MLM companies looking to sell lots of oils (much like Avon). These companies work on a commission basis and encourage reps to push information that’s not always safe or studied. I think much of the information on ingesting oils comes from these companies and sellers. I wouldn’t advise ingesting oils unless under the care of a natural doctor that knows what they are doing. One of the best sources for all-things essential oil safety is this independent site run by a certified aromatherapist: http://www.learningabouteos.com/. Plant Therapy also provides great information on their blog. Hope that helps :).
Essential oils have also shown to improve learning, memory and ability to focus. Both stimulating and sedative oils can be useful, as oils like peppermint can improve sustained attention over a longer period of time, while oils like lavender can be useful for people going through tough exercises or situations. Furthermore, they can be useful in relieving agitation in individuals with dementia. This is due to their calming and sedative effects. (10)
According to a systemic review and meta-analysis published in Pain Research and Treatment, there is a significant positive effect of aromatherapy, compared to placebos or control treatments, in reducing pain. Researchers evaluated 12 studies on this topic and found that essential oils were especially helpful in treating postoperative pain, obstetrical pain and gynecological pain. (14)
Aromatically – this may be the most well know way to use essential oils. Through a diffuser you’re able to fill the air with the essence of that essential oil allowing it to get into your lungs and therefore you’re blood stream. Be sure to look at your diffuser to get the correct water to oil ratio. Even if you don’t have a diffuser you could simply take a few drops from the bottle into the palm of your hands. Cup your hands around your mouth and nose and take deep breaths in of the oil.
There is no good medical evidence that aromatherapy can prevent or cure any disease. For cancer patients, aromatherapy has been found to lower anxiety and depression symptoms. In 2015, the Australian Government's Department of Health published the results of a review of alternative therapies that sought to determine if any were suitable for being covered by health insurance; aromatherapy was one of 17 therapies evaluated for which no clear evidence of effectiveness was found.
