There is no good medical evidence that aromatherapy can prevent or cure any disease.[5][16] For cancer patients, aromatherapy has been found to lower anxiety and depression symptoms.[17] 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.[18]
Tea Tree essential oil, also known as Melaleuca or Melaleuca Alternifolia oil, is one of the most widely used and extensively researched essential oils, making it a must-have for every home. Because the benefits of Tea Tree oil include cleansing properties and a refreshing scent, this versatile oil can be used for everything from home cleaning solutions to skin care. Keep a bottle of Tea Tree in your house to make homemade household cleaners, air fresheners, and linen spritzers. You can also find a world of uses for Tea Tree in your personal care and beauty routine. Incorporate this moisturizing yet cleansing oil into skin care applications and hair treatments for a spa-quality upgrade! You can use Frankincense to help heal Sunburn (dilute it with coconut oil), apply to cold sores or any infection as it helps kill the virus.

And a 2014 study involving 82 participants evaluated the effectiveness of aromatherapy for elderly people with chronic pain and symptoms of anxiety and depression. Researchers found that after four weeks of treatment with essential oils, there was a significant reduction in negative emotions, including feelings of anxiety, stress and depression, among the intervention group. (13)
The intervention group inhaled lavender oil for 15 days and researchers found that they showed significantly significant differences in their sleep quality compared to the control group that received no form of therapy. Researchers pointed out that lavender oil is a non-invasive, inexpensive and easily applicable intervention for hospital patients who are having trouble sleeping and experiencing anxiety. (21)
This is one of the most vital things you must know about essential oils: not all essential oils are created equal. In fact, most of them are worthless to your health and often synthetic. Therefore, when buying such oils — whether 5ml, 10ml or 15ml bottles — choose pure ones that are certified USDA organic, 100 percent pure, therapeutic grade and indigenously sourced.
Shown to the right is a bottle with a rubber dropper top. It's okay to use a bottle with dropper top to store essential oils that are blended with carrier oils at very low dilution for a few months or less. However, do not store pure, undiluted essential oils in bottles with rubber dropper tops. The rubber will turn to mush and ruin the oil. It's okay if the bottle has a plastic orifice reducer (euro dropper) insert inside the bottle as the material can withstand essential oils.
A pilot study published in Complementary Therapies in Clinical Practice found that the use of aromatherapy as a complementary therapy helped to reduce anxiety and depression scales in postpartum women. Women between zero and 18 months postpartum were divided into either a treatment group that inhaled a blend of rose and lavender oils or a control group that didn’t receive any type of aromatherapy. After four weeks, the women using aromatherapy had significant improvements in anxiety and depression symptoms compared to those in the control group. (12)

Adding essential oils to your bath is an amazing way to take a relaxing time-out during your busy day. Buy a box of simple Epsom salts as the base for your essential oils. If you just drop the oils into the water, they will not dissolve as nicely as they do when first mixed into the salts, who then dissolve beautifully. Please don’t combine any other chemically produced soaps or products into this mix in an effort to fully enjoy all the benefits of the essential oil and Epsom salts alone.
Oils with standardized content of components (marked FCC, for Food Chemicals Codex) are required[by whom?] to contain a specified amount of certain aroma chemicals that normally occur in the oil.[citation needed] There is no law that the chemicals cannot be added in synthetic form to meet the criteria established by the FCC for that oil.[citation needed] For instance, "lemongrass essential oil must contain 75% aldehyde to meet the FCC profile for that oil, but that aldehyde can come from a chemical refinery instead of from lemongrass." [14] To say that FCC oils are "food grade" makes them seem natural when they are not necessarily so.
The intervention group inhaled lavender oil for 15 days and researchers found that they showed significantly significant differences in their sleep quality compared to the control group that received no form of therapy. Researchers pointed out that lavender oil is a non-invasive, inexpensive and easily applicable intervention for hospital patients who are having trouble sleeping and experiencing anxiety. (21)
DO: Purchasing oils from reputable mail-order companies may result in obtaining higher quality oils at less expense than purchasing oils from a generic local health food establishment. Again, there is a wide variance in the quality of oils from company to company and store to store. Although AromaWeb does not make an endorsement of any establishment, the Global Aromatherapy Business Directory lists a variety of companies that sell essential oils and aromatherapy products.
You can use essential oils in any number of ways. For example, add them to body lotions or carrier oils, and then apply them topically. Try enhancing a facial toner, shampoo, or conditioner with essential oils. Or incorporate them into liquid soap, toothpaste, or mouthwash. You can also diffuse or spritz the oils throughout a room or pour them into a bath.
