do a simple Vinegar water boil 3x on the powdered rootbark..filter and combine the 3 liquids and reduce down to a small ammount and clean it up with some naptha(defat)...get a sep funnel or baster etc and seperate, saving the deffated liquid..evap that down in a food dehydrator or with a fan or something....when it's try grind it to a powder and mix in some sodium carbonate, a bit of water to make a paste and mix around every so often until it is dry. Then do 3 pulls on that with 99% iso, and evap it down, and if gunk or whatever drops out of solution in the evap dish, get a glass eye dropper or something and remove it, or remove the liquid from the dish to anothe dish leaving the crap behind..the resulting product will be smokeable..but it will consist of DMT, jungle DMT and DMT n-oxide..if you get it right, it shoud be yellowy orange..if it is red or purple, you didn't defat enough.. From there you can clean it up farther if you like by redisolving it in iso, some of the crap will drop out of solution and you can siphon off the iso once again leaving the crap behind.
I have tried this tek and it works...but if you dont defat enough the iso will pull lots of oils and shit and it will end up more impure and smoking it will be ghetto!..if you dont clean it up...if you want pure DMT and not the other cool alkaloids..than do a proper A/B.
