Try transdermally with emu oil.

I have tried lemon oil and found a faster onset (5-10 min) and almost euphoric rush with transdermal application compared with capping and digesting. I imagine the same could be said for a lot of essential oils.

I guess it also depends a lot on your liver biochemistry and how your body deals with it, my elemi oil smelled of what I imagine a citrus/ylang ylang combo would be like at 80:20 ratio.

Plenty more oils to test.
