This is where DoTerra RADICALLY differs: A vast majority of their oils are safe for ingesting. The reason is because they are Certified Pure Theraputic Grade Essential Oils (CPTG). The oil industry has been very unregulated for a long time – in fact, the FDA only requires oil companies to put 10% oil in a bottle and then they can put anything else in that they want (kind of like how perfume companies can get away with putting phthalates in their chemical cocktails). DoTerra has a very strict standard, and as many people state, they can tell this almost immediately with how powerful they smell.
Here are a few of the top-rated essential oil products on Amazon that may help relieve anxiety. If you’re thinking about giving them a try, be sure to loop in any other medical or mental-health professionals you’re currently seeing; they may be able to provide additional guidance or alert you to any potential side effects or interactions for which you could be at risk.
RC and Raven (YL Blends) are a few that I have used for myself and family for breathing issues. And Digize (also a Young Living Blend) is excellent for digestion, acid, and upset. Peppermint and Fennel are also options to look into. As far as best brand, you will have to do your research. I have been very happy with Young Living, but I know many will find the “best” from various sources to make up their essential oil cabinet. You will not want to use a vaporizer for your oils, I would suggest purchasing a diffuser which is designed to disperse your oils, over time essential oils will breakdown plastic tubing. A search on Amazon or Abundanthealth.com is a place to start looking at diffusers. You can also get a free one in premium kits sold by Young Living. Please feel free to contact me.
When applying an oil topically for the first time it’ a good idea to place one drop in an inconspicuous area to see how your skin reacts. To minimize skin sensitivity, mix with a few drops of Isagenix Coconut Application Oil. If skin discomfort or irritation occurs, discontinue use on the affected area. If the reaction persists it is best to consult with a doctor.
As you’re using essential oils, pay attention to how you feel. Scent is a highly individual experience. Each of us react to smells differently. The right scents for your relaxation and sleep are the ones that make you feel relaxed and sleepy! You may need to experiment with different oils before you find the right one for your nightly routine. If a scent makes you feel alert and awake, it is NOT the right one for sleep. But you can use it in the morning to help get you rolling into your day.
Don’t overdo it though. Remember, these oils are extremely concentrated. Prolonged exposure to essential oils can cause ill effects like headaches, nausea or other unpleasant symptoms. Vary your use with different oils of different chemical compounds so that they don’t build up in your system. And avoid letting your diffuser run all day, every day; there is a such thing as too much of a good thing.
Another common name for tea tree oil is Melaleuca. Used topically, this essential oil has purifying qualities to obtain and maintain clear skin and scalp. Used internally, it promotes a healthy immune system to relieve symptoms of a cough or a cold. Used aromatically, this oil fills the room with an outdoor, flowery scent that clears the air of seasonal and environmental threats.
There is also an argument from YL distributors that their oils come from the best crops in the world. As they grow their own crops and only use their own, not sure how they can claim it’s unarguably the best in the world. Every crop is different. Only sampling every crop, every batch would support that claim. Anyway, I am not a qualified aromatherapist either but my research suggests that YL oils and their advice might be best to avoid.
Like Jatamansi (Valerian is in the same family of plants), Valerian is a powerful anxiety-fighting essential oil and herb. It too increases levels of GABA and other relaxing/sedating neurotransmitters in the brain and body, however, it does so in interesting ways. One study suggests that Valerian extract may cause GABA to be released from brain nerve endings and then blocks GABA from being taken back into nerve cells, which increases its concentration in the nervous system.  In addition, Valerian’s medicinal compound valerenic acid inhibits an enzyme that destroys GABA, which is another way that valerian helps reduce anxiety, again by causing elevated levels of GABA in the brain and body. 
Mountain Rose Herbs – (This is the brand that I use for my business and my home) All organic & pesticide-free, wild-crafted (if available), a wonderful company with great smelling essential oils, for really decent prices. This company strives to help the environment in every way and is a zero waste company. They are certified organic by OTCO and they source their essential oils from reputable distillers that they know personally and trust.
Essential oils extracted from leaves, flowers, roots, and the bark of plants are usually steam distilled. Essential oils of lavender, rose, peppermint, sandalwood and eucalyptus are commonly obtained this way. Although the raw materials get heated during steam distillation, the volatile components are not heated to their individual boiling points, which may be much above the boiling point of water. So steam distilled essential oils are considered the next best thing to cold pressed essential oils.
Plants, like other living things, need to protect themselves from various types of predators. Plants use terpenoid compounds to deter insects and other animals from approaching them. Shawe pointed out that “insects are very rarely found on peppermint plants and the presence of linalol in the peel of citrus fruits confers resistance to attack by the Caribbean fruit fly.” 5 The Douglas fir tree releases a complex mixture of volatile oils, or terpenes, from their needles to defend against the spruce budworm. Even more fascinating is that the Douglas fir trees “will vary the composition and production of terpenes each year thus decreasing the ability of the budworm to develop widespread immunity to specific compounds.6
There's nothing like the refreshing scent of peppermint! Minty oils like peppermint, eucalyptus and spearmint are excellent for increasing mental clarity, concentration and staying alert. Whether you use them to feel fresh in the morning, or to snap out off a mid-afternoon lull - potent and powerful, minty oils are incredibly versatile and will give you an instant caffeine-free energy boost when you need it!
Also, if you drink it, you should only use a glass or stainless steel container. Glass is highly preferred over the two and the easiest for cleaning out of the previous EO. The smell/taste of an EO tends to “linger” a bit. This is usually a good thing I would think in say aromatherapy but in this case not so much…unless of course you prefer to use the same EO each time.
