The use of essential oils for therapeutic, spiritual, hygienic and ritualistic purposes goes back to ancient civilizations including the Chinese, Indians, Egyptians, Greeks, and Romans who used them in cosmetics, perfumes and drugs.[7] Oils were used for aesthetic pleasure and in the beauty industry. It was a luxury item and a means of payment. It was believed the essential oils increased the shelf life of wine and improved the taste of food.

There are also quite a few studies that have found essential oils to be helpful for hair growth. One such study, conducted in 2015, evaluated the efficacy of rosemary oil on patients with androgenetic alopecia, or male or female pattern baldness. Patients were randomly assigned to rosemary oil or minoxidil (a medication commonly used for hair loss) for a six-month treatment period. Researchers found that both groups experienced a significant increase in hair count at the six-month endpoint. They also indicated that scalp itching was more frequent in the minoxidil group. (17)
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.
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]
Some Essential Oils work best when they’re massaged directly onto the skin. For example, you can ease headache pain by rubbing one drop of neat Lavender Essential Oil onto your temples. Always use a base oil (like olive oil, safflower oil, or any other vegetable oil), and add a couple drops to that before applying to your skin. The only exceptions are Lavender and Tea Tree oil, which can be applied undiluted, if desired.

Beginning to use essential oils is the start of an incredible aromatic journey. I created AromaWeb over 20 years ago because essential oils played a highly beneficial role in my life and I was (and still am!) eager to share insight into the safe and effective use of essential oils. Below are several important aromatherapy tips for beginners and those that are new to using essential oils.
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.

Especially if skin sensitivity is a concern, definitely ALWAYS dilute your essential oil with a common neutral carrier oil (also called base oils) before application. Carrier oils are typically cold-pressed oils and do not evaporate like essential oils do, but they can go rancid where essential oils will not. Your choice of carrier oil will depend a bit on preference of smell, texture, and sensitivities to avoid allergic reactions. Popular choices for carrier oils are coconut oil, sweet almond oil, jojoba oil, avocado oil, sunflower oil or grape seed oil.
“An essential oil is a concentrated hydrophobic liquid containing volatile aroma compounds from plants. Essential oils are generally extracted by distillation, often by using steam. Some important information that you should know about an essential oil is the botanical name, chemotype (if applicable), origin of plant (this can drastically change the chemical constituents percentages) and extraction method.” (source)

Before we talk about where I buy my essential oils, I think it’s important to discuss two terms often used in the buying controversy: “therapeutic grade” and “certified pure therapeutic grade”. It’s important to note that there is no agency that regulates these terms, rather they are made up by the essential oil industry. Don’t let these terms fool you or effect your buying.
Used the right way, they can help you feel better with few side effects. For example, you may feel less nauseated from chemotherapy cancer treatment if you breathe in ginger vapors. You may be able to fight certain bacterial or fungal infections, including the dangerous MRSA bacteria, with tea tree oil. In one study, tea tree oil was as effective as a prescription antifungal cream in easing symptoms of a fungal foot infection.
