You'd probably need a vehicle such as DMSO to penetrate the skin, and depending on the strength of the extract you could take too much pretty easily.
thats exactly what i was thinking, dmso can dissolve many drugs and pass them trans dermal, even caffeine or sugar. the only side effect would be the taste.... i have been want to buy some for some time now to try out trans dermal caffeination.
anyone up to try this? mix some 20x extract in a teaspoon of dmso and rub all over you skin.
