i wonder why mhrb powder cannot simply be soaked in isopropyl alcohol and then the alcohol be evaporated?
You can extract using isopropyl alcohol, but you still need to basify. In a nut:
1. Evenly mix MHRB powder with an equal amount of sodium carbonate (available as Arm and Hammer washing soda)
2. Put you mixture in a large canning jar
3. Add your IPA to the mixture, seal and then shake the crap out of the jar
4. Leave the jar to sit for a few hours, shaking occasionally. I usually let it sit overnight but this is probably excessive
5. Pour out the IPA into another vessel (I find a pint glass works well), using a coffee filter to collect any solid material
6. Evaporate the IPA in nice flat dish
7. When full evaporated you should be left with a resinous material, anywhere from dark brown to red in colour, this is rich with DMT and other fun mimosa alkaloid but also some residual sodium carbonate and other crap left over. You can smoke it as is or dissolve it in warm IPA and then filter for a purer product
A few things to bear in mind. While this resin is smokable, it not exactly pleasant, I suggest using it to make changa, or taking it orally with an MAOI. You can substitute IPA with acetone and the sodium carbonate with edible lime, the main differences being the constancy of the final product. IPA produces a more solid resin, while the stuff pulled with acetone never seems to dry.
I like this method a lot personally, it's simple and IPA and sodium carbonate are pretty benign when compared to lye and naphtha, they work fine of course and produce a great product, but I'm not the most attentive or dextrous of people and accidents do happen.
