Not all essential oils are created equally, though, and certain oils are thought to better target anxiety while others may have different benefits. "Just make sure any oil you use is completely natural, organic plant essence," says Gillerman. Essential oils are not regulated by the U.S. Food and Drug Administration, but you should look for options that are certified organic, says Gillerman. "It's your surefire way of making sure that you are getting an essential oil that is not diluted or polluted with a toxin or petrochemical."
Purity is a major issue when using essential oils, particularly if you are using them therapeutically, internally or topically.  The most important issue is to know your company.  What type of testing do they do?  Do they test all batches?  Are the oils grown indiginously?  How are they harvested?  If your oil company cannot answer these questions to your satisfaction, then use another company.  In my opinion, there are a few companies that have consistently high quality oils.  Good luck!
There are many different kinds of essential oils, and they’re all different to one another; even if they share a range of uses. Where some can be relied upon to help fight off illness, others can help individuals that struggle to fall asleep at night. Below are some of the many liquids that can be found on offer at leading brands such as doTERRA – and their uses.
Poisoning by lavender is uncommon. In the late 1960s and early 1970s, the LD50 values for lavender taken orally and applied topically were determined. In mice, the oral LD50 was 13.5 ± 0.9 g/kg, where central nervous system depression occurred 10 to 15 minutes following ingestion and death occurred 1 to 3 days later.47,48 Similar results were observed in rats.47 For dermal applications, the LD50 was greater than 5 g/kg, with no systemic symptoms or deaths in rabbits observed up to 14 days.48 In humans, an 18-month-old boy ingested homemade lavandin (Lavandula x intermedia) extract. Three hours following the ingestion, the child developed confusion and deep drowsiness, with adaptive motor response to painful stimuli indicative of moderate brain injury (Glasgow Coma Score = 9). His neurologic status normalized within 6 hours of hospitalization, and a follow-up electroencephalogram was normal at 24 hours. Comparative toxicology analysis between the boy's blood, urine, and pure lavandin extract showed linalyl acetate, linalyl formate, and acetone were detected in all samples. Acetone, which was a confounding factor for coma in the poisoning, was found to be slightly higher than normal in healthy adults and was concluded not to be the cause of the central nervous system depression.49
The nebulizer diffuser is similar to the ultrasonic diffuser, except it does not require water. As a result, this type of diffuser provides a continuous supply of concentrated essential oils, doesn’t require refilling the water tank, and has a much lower risk of mold growth. But these units can be more expensive, louder, and use up the oils more quickly.
Hi! I suffer from connective tissue disease (similar to lupus or RA in pain), and I use lemongrass DILUTED in coconut oil. It is amazing how well this works for pain. Peppermint is awesome for headaches as well as nausea, and marjoram is another pain med. Some oils don’t do much for me except smell really good, but those three have been invaluable. I get mine from doTerra, but I’m going to check out the other site mentioned by Crunchy Betty. Thanks!
Some essential oils have sedative properties, which can be helpful for people who are having trouble falling asleep or sleeping through the night. Lavender oil, in particular, is known to be an effective sleep aid because of its ability to leave you feeling relaxed and calm. Some other oils that can be used to promote restful sleep include Roman chamomile, ylang ylang, bergamot and vetiver.
To test if you’re sensitive to an essential oil (which is probably best to do before using it in a skincare preparation): Combine one drop of essential oil with 1/2 tsp carrier oil (like olive, jojoba, or sweet almond). Rub this on the inside, upper portion of your arm and wait a few hours. If no redness or itching develops, you’re most likely not sensitive to that essential oil.
Dr. Robert Pappas says, “There are a lot of companies out there selling essential oils and most of them have no ability (or in many cases no desire) to do the necessary quality control to verify what they are getting from their supplier before they pass it on to their customers.” The GC/MS test determines quality and can show evidence of adulteration, although it is not perfect. Good companies will employ other tests as well like, Organoleptic (sensory tests), or FTIR (Fourier transform infrared spectroscopy).
Looking for increased mental clarity and focus? When you're dealing with the challenging demands of the daily grind, having a moment of harmony and peace is essential for your overall well-being and mental health. Sandalwood oil, with its amazing woody aroma, has a powerful therapeutic effect on the brain's limbic system and is an excellent emotional balancer.

I was wondering. I have a friend that has neuropathy. I do too. I use wintergreen diluted with fractionated coconut oil or a blend called deep blue, and sometimes peppermint oil for this. The friend asked the question, Can you mix all oils safely? As she has found on pinterest a recipe for it where you mix 8 different oils. I am not sure of the oils she has listed, but is this safe?
Frankincense has been called "the holy grail of essential oils" because it has some pretty astounding health benefits, both mentally and physically. Studies have found that it's capable of inducing timely apoptosis, meaning that it can prevent and potentially kill cancerous cells. It also has anti-inflammatory and skin-healing effects, so it's a staple in skin-care. When it comes to mood benefits, one study even reported that it was able to reduce pain and prompt relaxation in women during labor.
Aromatherapy is quite popular these days, and it is one way to use many of the essential oils out there. When looking at the best essential oils for diffusers, it is important to note the individual benefits they provide. You can visit an alternative health practitioner, or you can buy your own diffuser and oils for home use. Here we discuss some of the most popular essential organic oils for aromatherapy.
I have yet to come across a YL distributor who is a qualified aromatherapist. Not saying they don’t exist, I just haven’t met one and I check at every trade fair I visit. Possible that the reason you got vague answers from them is because they are preaching the company line that they have been taught without actually knowing/understanding the answer?

THIS TRUELY was an awesome deal…very pleased and will purchase again from Art Naturals.”  – Lisa Korcek
Ellen – Im sorry but you are mistaken. Essential oils ARE able to be ingested in their purest, natural form. The FDA even acknowledges this and has its OWN list of Essential Oils Generally Recognized as Safe for human consumption. If needed I can gladly link you. The FDA has in fact gone after them, not for “practicing medicine”, but for some of the uneducated reps who made claims that EO’s cured Ebola. At the same time, Dr Bronners people among OTHER companies received the same letters. They also did not file anything, they have sent them letters with “their demands” and now these companies need to meet them. Do not make a mountain out of a mole hill. I am with Young Living oils- because I care where my product comes from.
Do not take any oils internally and do not apply undiluted essential oils, absolutes, CO2s or other concentrated essences onto the skin without advanced essential oil knowledge or consultation from a qualified aromatherapy practitioner. If you are pregnant, epileptic, have liver damage, have cancer, or have any other medical problem, use oils only under the proper guidance of a qualified aromatherapy practitioner. Use extreme caution when using oils with children. It is safest to consult a qualified aromatherapy practitioner before using oils with children.
