Just a thought:

This product is so potent, if I could play with it some, I might try mixing a few drops of the liquid oil-based formulation into a small amount of "carrier oil," to see the effects of using this in a little weaker formulation.

"Carrier oils" are oils used for massage, etc. These include jojoba, almond and other oils.

I encourage people to try it at full-strength first, if trying it at all.
Remember: this strong formulation is intended for the feet.

I will add a warning which people working with essential oils already know:

Never place a strong version/dilution of any essential oil, or any essential oil mixture, on the spine or neck. Only very, very diluted essential oil mixtures can be safely applied in these regions.
