There are several viable methods you can use to inhale these oils...

  • Pop some of your favorite oil on a tissue or handkerchief
  • Use an inhaler adapted for aromatherapy
  • Steam inhalation with boiling water
  • Enjoy the vapors from an essential oil diffuser

Using an essential oil diffuser is one of the smartest and most economical ways to enjoy the full aromatherapy benefits.  A humidifier is also a great tool if you want to enjoy other benefits of breathing in humidified air along with your essential oils. These devices are easy to use and they will also fragrance your home every time you turn on your humidifier or oil diffuser.

  1. Hello, I wonder if I can use a non-oil scent?
    That is, I have the product CALIFORNIA SCENTS ORGANIC SPILPROF
    And how I like the smell, I got into the water of the diffuser to give a scent to the house, I wonder if this can be done and if it is normal to breathe this air?

    1. Hi there Edson!

      You will be fine using a fragrance oil from California Scents.

      You won’t get the same therapeutic benefits as using essential oil. It’s safe though and you will perfectly OK to breathe in the fragrance.

    1. Hi – you should be able to use the oils so long as you have a humidifier designed for essential oils. Many have a special holder or cup for the oils. If you use the oils in one not designed for them, you will have a mess on your hands! Best of luck.
