One of the key differences between natural and synthetic scent molecules is their frequency, or in the case of synthetics, their lack of frequency.
Every living organism has a frequency measured in megahertz (MHz) which can indicate its health & potency. For example a healthy human body vibrates at a significantly higher frequency than when it's sick.
When it comes to scent, essential oils are alive and each one resonates at its own frequency. The highest (and my favorite) is pure rose oil which vibrates at around 5 times the frequency of a healthy human body!
So next time you stop & smell the roses just think, you're literally breathing in a good vibration.
