Some studies indicate that there's a benefit to using essential oils whileothers show no improvement in symptoms. Clinical trials have looked atwhether essential oils can alleviate conditions such as:

How Can You Use Essential Oils Safely?
The quality of essential oils on the market varies greatly, from pureessential oils to those diluted with less expensive ingredients. Andbecause there's no regulation, the label may not even list everythingthat's in the bottle you're buying. That's why essential oilsshould not be ingested.
Johns Hopkins also advises against using essential oil diffusers, small householdappliances that create scented vapor. Diffusion in a public area orhousehold with multiple members can affect people differently. For example, peppermint is often recommended forheadaches. But if you use it around a child who's less than 30 months old, the childcan become agitated. It could have a negative effect. Additionally,someone with fast heartbeat can react adversely to peppermint.
The safest ways to use essential oils include:
- Aromatherapy accessories: Necklaces, bracelets and keychains made with absorbent materials you apply essential oils to and sniff throughout the day.
- Body oil: A mixture of essential oils with a carrier oil such as olive, jojoba or coconut oil that can be massaged into skin. Because essential oils are concentrated, they can cause irritation. Avoid using them full-strength on skin.
- Aroma stick: Also called an essential oil inhaler, these portable plastic sticks have an absorbent wick that soaks up essential oil. They come with a cover to keep the scent under wraps until you're ready.
Allergic reactions to essential oils
A small number of people may experience irritation or allergic reactions tocertain essential oils. You're more likely to have a bad reaction if youhave atopic dermatitis or a history of reactions to topical products.Although you can experience a reaction to any essential oil, some are morelikely to be problematic, including:
- Oregano oil
- Cinnamon bark oil
- Jasmine oil
- Lemongrass oil
- Ylang-ylang oil
- Chamomile oil
- Bergamot oil
Because pure essential oils are potent, diluting them in a carrier oil isthe best way to avoid a bad reaction when applying directly to the skin. Ifyou get a red, itchy rash or hives after applying essential oils, see adoctor. You may be having an allergic reaction.
Which Essential Oils Are Best?
There are dozens of essential oils, all with different fragrances andchemical makeups. Which essential oils are best depends on what symptomsyou're looking to ease or fragrances you prefer. Some of the most popularessential oils include:
- Lavender oil: Many people find the lavender scent relaxing. It's often used to help relieve stress and anxiety and promote good sleep.

How to find quality essential oils
The most important thing to consider when shopping for essential oils isproduct quality. But figuring out which oils are the best ischallenging, since there's no government agency in the U.S. that provides agrading system or certification for essential oils. A big problem? Manycompanies claim their essential oils are "therapeutic grade," but that'sjust a marketing term.
Unfortunately, there are lots of products you might find online or instores that aren't harvested correctly or may have something in them thatisn't listed on the label.
Here are some tips to help you shop for pure essential oils:
- Look at the label: It should include the Latin name of the plant, information on purity or other ingredients added to it, and the country in which the plant was grown.
- Evaluate the company: Purchase products from a well-known and reputable aromatherapy company that's been around for several years.
- Choose dark-colored, glass containers: Pure essential oils are highly concentrated. They can dissolve plastic bottles over time, tainting the oil. Most companies package essential oils in small brown or blue glass bottles to protect the quality.
- Avoid "fragrance oils": Fragrance or perfume oils are made from essential oils combined with chemicals or entirely from chemicals. They're not suitable for aromatherapy — instead, look for bottles that contain a single essential oil in its purest form (100% essential oil with no other fillers).
- Compare prices: Essential oils range in price, depending on how involved harvesting and production are. Within a line, there should be a wide variety of prices — rose absolute or sandalwood oils will be more expensive, while sweet orange oil will be on the less expensive end. If you find a rock-bottom price for an expensive essential oil, it probably isn't pure.
Essential oils can lift your mood and make you feel good with just a whiffof their fragrance. For some people they may even help alleviate thesymptoms of various conditions. For more information on how to incorporatethem into a healthy lifestyle, consult an integrative medicine expert.
