Essential Oils Ultimate 2019 Guide: Uses, Types, Anti-Aging Skincare And Risks



Essential Oils Ultimate 2019 Guide

Essential oils seem to be a modern hype, but in truth they’ve been used in traditional medicinal systems around the world for thousands of years. More recently, medical researchers have studied essential oils for the therapeutic effects of their numerous naturally-occurring chemical compounds. Essential oils can be used as natural remedies for a host of short-term and chronic ailments, whether physical or psychological in nature. They also have beauty-enhancing properties for your skin and hair and can be used to clean your home effectively without chemicals.

In this guide, you’ll learn how to use various essential oils effectively and safely for a wide array of benefits.

What Are Essential Oils?

Essential oils are extracted or distilled from herbs and plants known to have medicinal value. They’re the most concentrated form of a plant or its seed, giving you its most potent therapeutic properties.

Essential oils have strong fragrances and often the most active compounds in them are the aromatic ones. The molecules in these compounds are tiny compared to the larger molecules found in cooking oils. Their small size allows them to enter your bloodstream and even pass through the blood-brain barrier. This way, they directly modulate chemical systems in the body. Many nutrients can’t do this even when ingested internally.

What The Research Says

Medical studies have determined that many essential oils have antiviral, antifungal and antibacterial properties that make them useful in fighting infections and treating wounds without producing side effects synthetic drugs can cause. In fact, studies continue to show that essential oils, when used at appropriate doses, produce virtually no adverse side effects.

Many essential oils are being studied for their anticancer effects, which may be effective for cancer treatment or adjunctive therapy. Certain compounds in various essential oils are able to trigger apoptosis, or cell death, in the case of cancer and tumor cells. Other compounds repair DNA, protect cells from oxidative damage linked to cancer and stop the proliferation of cancer and tumor cells.

Essential oils also contain compounds commonly used in pharmaceutical-grade skin and hair care products that promote healing, beauty and anti-aging. They can directly modulate the immune system, boosting the production of antibodies in the face of colds and flus. Some essential oils act as natural remedies for managing symptoms of illness, from mucous congestion to allergic reactions and digestive ailments.

Mounting research points to the incredible ability of essential oils to produce meaningful psychological effects. By directly interacting with the brain’s chemistry, the aromatic compounds in essential oils can have antidepressant effects, reduce anxiety, insomnia, panic attacks, agitation and everyday stress.

Ways You Can Use Essential Oils


Aromatherapy is the inhalation of essential oils for therapeutic purposes. The most common way to inhale essential oils is to use a diffuser, which come in different sizes to accommodate different spaces. Simply fill your diffuser with water and add a few drops of essential oil, as per the instructions that come with it. The larger your diffuser, the more drops of oil you’ll need to add. Plug it in, turn it on, and the diffuser will go to work releasing essential oil-infused vapors that permeate the air you breathe.

You can also enjoy aromatherapy using aromatherapy sprays or making your own. These are generally water-based sprays you can use as air fresheners, perfume or to spray on your pillow before going to bed at night. You can also enjoy aromatherapy by adding a few drops to a hot bath. When you’re in a pinch, you can simply open a bottle of essential oil and take in the smell directly for instant effects.

Hot Steam Inhalation

Some essential oils, such as tea tree, eucalyptus and frankincense oils, work as decongestants and expectorants to expel mucus from the lungs and sinus cavities. The best way to use them is to add a few drops to a bowl of steaming hot water and inhale the warm vapors for up to 5 minutes. Be sure to close or cover your eyes so that they don’t come in contact with the essential oils.

Topical Use

Essential oils are used topically for natural skin care, first-aid applications or to enjoy their aromatherapeutic effects. Because essential oils are highly concentrated, it’s important to take caution in applying them directly to the skin. Some essential oils, like clove oil, cause direct skin irritation and should be avoided for topical use unless diluted. Others are very gentle on the skin, such as lavender oil and chamomile oil. For instant aromatherapy benefits, you can put 2 or 3 drops on your fingers and rub these oils into your temples or on your neck to inhale the aroma.

However, as a general rule, it’s wise to dilute essential oils with a carrier oil before using them on your skin, as potential allergic reactions can occur. You also don’t want to use a large amount of undiluted essential oil on your skin, because the tiny molecules absorb very quickly into your bloodstream and have powerful internal effects.

Carrier oils are oils with much larger molecules that help hold essential oils on the surface of your skin, causing them to absorb into the bloodstream much more slowly. Some good choices are jojoba oil, coconut oil, grapeseed oil and almond oil. You can also combine essential oils with high-quality lotions like raw shea butter and raw cacao butter.

When diluting essential oils, use a 1:10 ratio, which is equal to five drops of essential oil per half-teaspoon of carrier oil.

Hair Care Use

Essential oils have rejuvenating effects on your hair. They can serve as natural replacements for chemical-based products when you use them for DIY haircare recipes, or they can provide a boost to your existing hair care routine. Coconut oil is a great carrier oil to use when you apply essential oils to your hair, since it benefits your hair’s structure and can prevent and treat dandruff. If you want to stimulate hair growth, jojoba oil is a great option.

To reap the benefits of essential oils for your hair, combine them with a carrier oil at a 1:10 ratio and massage the mixture into your scalp and throughout your hair strands. Let it sit as a conditioner for at least 30 minutes, and then wash it out.

Internal Use

You can even use essential oils as dietary supplements, but only in very small amounts. Not all essential oils are safe for internal use. When using essential oils internally, it’s important to use 100 percent pure oil from a brand labeled “therapeutic grade.” Naturally, non-GMO and organic essential oils are optimal, especially for internal use.

Take no more than 2 to 3 drops of an essential oil per day. You can take them under your tongue for easy absorption, mix them with a spoonful of honey or add them to water, tea or juice.

Cleaning The Home

Essential oils don’t just make your house smell clean; they also have germicidal effects without the harmful chemicals you find in conventional cleaning formulas. Antibacterial, antifungal and antiviral essential oils like thyme, tea tree, lemon, clove, orange, lavender, peppermint, cinnamon and lemongrass can all be used in disinfectant solutions for sanitizing the kitchen, bathroom and entire home.

Here’s a recipe for a natural DIY essential oils all-purpose cleaner:

  • 1 tsp borax
  • 1/2 tsp washing soda
  • 1 tsp liquid castile soap
  • 15 drops of disinfectant essential oils of choice
  • 2 cups water
  • Spray bottle
  • Combine all ingredients into the spray bottle and shake well.

Blending Essential Oils

Blending your essential oils together is a great way to create awesome fragrances and get the most out of the medicinal compounds essential oils offer. However, there is a science to it.

In creating an essential oil blend, you want to start with its therapeutic purpose and application. Then you can write a list of all the essential oils that can serve the purpose you’re aiming for. Narrow down the list based on safety considerations depending on how your essential oil will be used (inhaled, applied topically or taken internally). Consult the safety information that comes with your essential oils, or use a credible website or book to research essential oil safety.

Next, pull from your list a combination of oils that compliment each other. Essential oils are grouped based on their aromas.

These groups include:

  • Citrus – grapefruit, orange, lemon, bergamot, lime, tangerine
  • Medicinal – eucalyptus, tea tree, rosemary
  • Spicy – clove, cinnamon, nutmeg, aniseed, black pepper, cumin, nutmeg, ginger, coriander
  • Earthy – oakmoss, vetiver, patchouli, valerian, angelica
  • Woodsy – cedarwood, sandalwood, pine, wintergreen
  • Floral – jasmine, chamomile, rose, ylang ylang, geranium, lavender, neroli
  • Herbaceous – hyssop, marjoram, basil, clary sage
  • Minty – peppermint, spearmint

One way to blend essential oils is to choose oils from the same category, as they blend well together. Use equal amounts of each oil to do this.

Another option is to blend oils that represent two or three different categories. This is generally done at a 4:6 or 2:3:5 ratio. Some essential oil categories have stronger scents than others. To create a balance, use the strongest smelling oils in the smallest amounts, and the more subdued scents in larger amounts. For example, citrus oils and medicinal oils have strong scents that can overpower the more mellow aromas of woodsy and earthy oils.

When combining oils from different categories, keep in mind that:

  • Citrus oils blend well with floral, minty, spicy and woodsy oils
  • Floral oils blend well with woodsy, citrus and spicy oils
  • Woodsy oils blend well with all other categories
  • Herbaceous oils blend well with woodsy and minty oils
  • Earthy oils blend well with minty and woodsy oils
  • Medicinal oils blend well with woodsy oils
  • Spicy oils blend well with floral, citrus and woodsy oils

Essential Oil Safety


Not all essential oils are safe during pregnancy. In fact, some should be avoided if you’re pregnant because they trigger effects on the uterus that can put your pregnancy at risk. Although lavender is a popular and common oil used to bring on relaxation, pregnant women should avoid it because it encourages menstrual flow and may increase the risk of miscarriage. Pay attention to warnings that come with the essential oils you purchase or consult with a doctor or naturopathic professional to ensure you’re using oils that are safe for pregnancy.

Allergic Reactions

Just because essential oils are all-natural doesn’t mean you can’t have adverse reactions to them. If you’re sensitive to strong fragrances or have allergies or asthma, some essential oils may cause irritation or even an allergic reaction. If you know you’re prone to allergies, try essential oils with caution in small amounts to test your reaction. Stop inhaling any oil that causes discomfort.

Drug Interactions

Because they contain potent, drug-like chemical properties that directly modulate systems in the body, essential oils can interact with several medications. If you’re on medication, it’s important to consult with your physician about which essential oils are safe for you to use.

Safe Doses

Once again, even though essential oils are natural, they still exert powerful effects that shouldn’t be taken lightly. Even if you’re not using oils topically or internally, you still don’t want to inhale essential oils in excess. It’s best to use a diffuser for 30 to 45 minutes at a time and use the amount of oil recommended in the diffuser’s instructions. Avoid leaving your diffuser running overnight.

Take extra precaution using essential oils that work as decongestants and expectorants and use only the amount you need to see symptom improvements. Inhaling too much can cause excessive coughing and runny nose.
