Contrary to popular belief, there is a school of thought that says essential oils hold vibrational frequency and that these can be measured like we can measure sound. I have been looking for information regarding the vibrational frequencies of scent for so long, and I finally found some interesting info on sites relating to kinetic theory and holistic medicine. According to one, essential oil frequencies start at 52 MHz and go as high as 320 MHz. Among these, rose oil has the highest vibrational frequency at 320 megahertz, the highest of any known substance. When we reach for scents, are we smelling for our health without knowing it? Maybe there's more to the saying, "take time to smell the roses" than we like to believe.
