Swanson Health's Complete Beginner's Guide to Essential Oils
What is Aromatherapy?
Aromatherapy may promote relaxation and help relieve stress.1 It has also been used to promote sleep,1 support overall health and wellness and it may even help support healthy blood pressure.2
Aromatherapy uses oils extracted from flowers, seeds, leaves, roots, fruit and twigs for special effect. These essential oils are formulated to work in harmony with the body and may have an ability to affect a person’s well-being.
Derived from the parts of plants or trees, essential oils possess a complex nature that is difficult to reproduce outside of nature. In fact, some oils contain substances that don’t occur anywhere else naturally.
Essential oils have been used for thousands of years as stimulants, sedatives, and for religious and medicinal purposes.3 Aromatherapy is the century-old practice of using volatile plant oils, also referred to as essential oils, to support overall health and well-being.
It is part of the holistic healing spectrum that, in addition to essential oils, also utilizes other natural ingredients like vegetable oils, jojoba (a liquid wax), herbs, sea salts, clays and muds.
Aromatherapists apply some aromatherapy oils directly to the skin via aromatherapy massages, but they also use the oils to freshen the air of their living spaces via sprays or essential oil diffusers.
The oils can also be inhaled directly, although one should be careful not to swallow or consume the liquid oils.
"Practitioners of aromatherapy believe that fragrances in the oils stimulate nerves in the nose. Those nerves send impulses to the part of the brain that controls memory and emotion. Depending on the type of oil [the scent], the result on the body may be calming or stimulating." (UPMC4)
Health Benefits of Aromatherapy
Take a whiff of the air around you. What do you smell? Are you immediately put in a good mood with the smell of fresh cut flowers? Suddenly craving pie with the smell of baked apples and cinnamon wafting through the halls? Or feel like gagging after being blasted with exhaust from the bus?
It’s easy to see how our sense of smell impacts our feelings. The sense of smell is incredibly powerful. Your body can distinguish more than 1 trillion different scents.5 But, aromatherapy isn’t just about appealing smells; it also offers many potential health benefits including the following:
- Supporting relaxation and stress relief1
- Aiding mood1 and well being
- Supporting immune system6 and circulatory health2
Aromatherapy can be a great, natural, complementary health treatment in a variety of situations. To find out which scents may help you, find an aromatherapy book at your local library or do some online searching to find out about popular essential oils and get recipes for mixing your own rejuvenating scents.
Blending Essential Oils
Different oils can be blended together to achieve a synergy. This means that the respective powers of the oils change to enhance their energy. When a level of power has been reached, you achieve a synergy. Recipes for blending need to be followed exactly and the oils should be left to age for at least a week before adding them to carrier oils.
Essential Oil Dilution
Once you have chosen your essential oil, you can add it to base products to enhance your favorite health and beauty items. To dilute essential oils, simply add them to unscented bath oils, hand and body lotions, massage lotions and shower gels.
- Massage – 5 drops per tsp of base oil or lotion
- Inhalation – 1 or 2 drops in boiling water or on a tissue
- Bath – Up to 6 drops in ¼ cup carrier oil (we like jojoba oil), then add 8 to 10 drops of blended oils to bath water
- Sauna – 2 drops to 2 ½ cups water
- Facial – 2 or 3 drops in base product
- Foot Bath – 8 drops in bowl of water
- Facial Sauna –10 drops in bowl of water
- Cleanser – 20 drops in 4 ounces of base product
- Body – 5 to 15 drops in base product
- Chest Rub – 10 to 20 drops to 1 oz of carrier oil
- Laundry Wash – 10 to 20 drops per load
- Vacuum Cleaner – 5 to 10 drops
- Auto Vent Outlet – 2 or 3 drops
- Artificial Holiday Tree – 10 to 15 drops in 8 ounces of water
Common Carrier Oils for Essential Oils
The healing scent of an essential oil can evaporate quickly, so they are often combined with a carrier oil. Carrier oils usually come from the fatty portion of a plant and help the essential oil's scent maintain for a longer duration of time.

Support the health of your scalp by adding a few drops of lavender, cedarwood or basil to your shampoo. Try adding rosemary oil to your shampoo to boost volume and increase circulation in the scalp.10

Add two drops of rosemary oil to your skin cream for antioxidant support and protection against oxidative stress.11

Add up to 5 drops of an essential oil to a teaspoon of carrier oil, such as sweet almond, olive, apricot kernel, borage seed, jojoba, sesame, sunflower or wheat germ oil.
- Add to your hot tub or bathwater
Add up to 6 drops of essential oils to ¼ cup of your favorite carrier oil (we like jojoba oil) before adding 8 to 10 drops of the blended oils to a bath. Avoid culinary oils including cinnamon, lemongrass and peppermint as they can cause skin irritations.
Which Essential Oil Can Support the Health of Your Hair?
Not only is lavender a perennial favorite among aromatherapists, but research also shows that it can support hair health10 when used regularly to massage the scalp. Here's a quick at-home, step-by-step lavender massage guide for your hair and scalp:
- Warm about half a cup of olive oil (not too hot).
- Blend in about 10 drops (or to your preference) of lavender oil.
- Apply this blend to your hair and gently massage your scalp.
- Wrap a warm towel around your head, sit back and relax for about 20 minutes.
- Follow it up with a natural shampoo and conditioner.

Use Lavender oil in baths, sprays, lotions, oils and more as a part of your bedtime ritual since lavender may promote a calm and relaxed feeling. Make a quick lavender-scented pillow insert by adding 3 drops of lavender oil to a wash cloth or linen square and placing it inside your pillow case. Make your own calming body oil by adding 3 to 5 drops of lavender oil to 2 tablespoons of a carrier oil like sweet almond or jojoba oil to support skin health and relaxation, especially during the dry winter months.
How to Use Essential Oils for Home & Hearth

Place one drop of lavender oil on a cotton ball or piece of cloth to help temporarily get rid of moths and mosquitoes.

Thirty minutes before burning a fire log, place one drop of cypress, pine, sandalwood or cedarwood oil on it. Do not use several perfumed logs at a time; a little goes a long way.
- Stuffed animals
Soothe your kids with the calming scent of lavender or chamomile on their stuffed animals. Place a stuffed animal in a plastic bag, add a few drops of essential oil and close the plastic bag overnight. The following day the stuffed animal will have the dispersed scent and can be used for up to two weeks before reapplying more oil.
