“Essential oils are fantastic. They have many advantages”, says the specialist in integrative medicineYufang Lin, MD. "The problem is how people use them."

Here is information on 11 essential oils, their benefits, and how to best use them.

What are essential oils?

Essential oils are concentrated extracts from plants.

“Plants consist of building materials and secondary plant substances. These chemicals have properties that benefit not only the plant but also humans,” explains Dr. Lin.

A large amount of plant material is required to create essential oils, which can make some of them more expensive. For example:

  • About 250 pounds of lavender flowers will produce 1 pound of lavender essential oil.
  • About 5,000 pounds of rose or lemon balm petals will yield 1 pound of rose or lemon balm essential oil.

"Because so much of the plant is needed to make an essential oil, it's a powerful botanical medicine," says Dr. Lin

Benefits of essential oils

Essential oils can be used in aromatherapy, a type of complementary medicine that uses scent to improve health, or applied topically to the skin.

Studies have shown that essential oils can help:

  • Improves mood.
  • Improve work performance with less stress and more focus.
  • improve sleep
  • Kills bacteria, fungi and viruses.
  • Reduce anxiety and pain.
  • Reduce inflammation.

How to use essential oils

Because essential oils are so powerful, Dr. Lin needs you to pay attention to why and how you use them. Only small amounts are used, usually just a few drops.

"It's also a good idea not to use them routinely, as your body can get used to them and decrease their effectiveness," she says.

Here are some ways you can use essential oils:

distribute them

You can diffuse essential oils, which is a type of aromatherapy.

"It's a great way to quickly change your mood. When inhaled, the aroma of the oil immediately stimulates the central nervous system and triggers an emotional response," explains Dr. Lin "It can quickly reduce anxiety and stress responses ".

Mix essential oils and water in an essential oil diffuser and turn on the magic. A diffuser is a device that disperses small oil particles throughout the room for you to inhale. Follow your diffuser's instructions for the correct ratio of oil to water.

There are several other methods of aromatherapy. "Whichever method you choose, avoid direct contact with the essential oil and dilute it first," says Dr. Lin.

Other aromatherapy methods include:

  • The old way.Inhale the aroma deeply after opening the bottle.
  • dry evaporation.Place a few drops of essential oil on a cotton ball and smell the aroma as it diffuses.
  • steam inhalationAdd a few drops of essential oil to a bowl of hot water. Place your head over the bowl, a towel over your head, and breathe in the steam.

One caveat is that aromatherapy may not work as well for older adults with dementia or behavioral problems, notes Dr. Fitted. This may be because people tend to lose their sense of smell as they get older.

Roll directly on your skin

You can also reap the benefits by applying essential oils to the skin where they are absorbed into the body. But dr. Lin cautions against applying most essential oils directly to the skin without diluting it.

"With a few exceptions, it's best to dilute the essential oil with a carrier oil like coconut or jojoba oil to avoid skin irritation," she says.

Some people place their essential oil blend in a small roller ball bottle for ease of use.

Take them

Some people take essential oils orally in teas, supplements, or even through a drop or two on the tongue.

"Unless directed by a trained herbalist, I advise against using them this way. Because they are so strong, they can be harmful," advises Dr. Lin "Even with just a few drops of essential oil, you are ingesting a large amount of matter vegetable without realizing it. They can even burn the lining of your mouth."

Some food recipes call for essential oil such as orange, but always double check the dosage and follow the directions carefully.

Be careful when using essential oils on children, people with compromised immune systems, pregnant women, and the elderly.

“Some essential oils can be harmful to the liver and nervous system when used in excess. Tea tree oil and eucalyptus oil have also been known to cause seizures," warns Dr. Lin. "They are also poisonous to animals."
