I have plans of trying. In theory it should work as well as any other experiment, but I have no clue until I try it. I think it has possibilties, unless the herbs also have other effects no one is aware of as of yet and when mixing with the spray bases, these herbs can show benefits in ways no one could ever suspect...so far all good. To make a sleep eze spray will be very simple, I have all the ingredients. I will give it a try one day soon.
