Essential oils are bottled plant extracts. They’re made by distilling or  pressing plants, flowers, bark or other natural items to trap the  compounds responsible for their fragrance, according to John Hopkins Medicine. More importantly, the unique aromas have been  utilized in healing practices by various cultures for thousands of  years. 

Michelle Davila, ND, a naturopathic doctor with the integrative medicine department of Beaumont Health in Grosse Pointe and Royal Oak, Michigan. When you breathe in an essential oil, the scent molecules travel from the olfactory nerves directly to the brain. Here, they interact with a region known as the limbic system, which regulates emotions,  memories, and sensations, Dr. Davila says.

The scent molecules can also be absorbed into the bloodstream when applied to the skin. Once in the bloodstream, essential oils distribute throughout the body to potentially enhance different  aspects of overall health, according to Davila.

In other words, essential oils have proven to be a helpful approach for many health concerns, from stress and insomnia to pain and nausea. Combine that with the matching resonance of the solfeggio sound frequencies and you have a powerful combination for holistic wellness.
