The best way that i know of to extract jungle spice follows. Please note that one can use (and i have done so successfully) Xylene and d-limonene in similar procedures. But, this procedure focuses on the use of Toluene as a non-polar solvent. A famous paper by a psychonaut named Entropymancer is frequently referenced, but has since become outdated. There has been a lot of speculations as to the content of jungle or so-called full spectrum spice, but an underground chemist has done a successful GC/MS and confirmed it is just N,N DMT and DMT-Oxide or similar. Not real big mystery afterall. But, it is definately in a different form than the freebase. PLEASE NOTE: If you want to convert jungle or full-spectrum spice to freebase you will need a special tek (i hope to be able to post something on this soon). Simple recrystallization in warm Heptane probably would not work well enough or preserve yield. Materials: Your spent mimosa marc (aka mud) - the left over MHRB after you've done the basic N,N DMT extraction. Toluene Measuring glass A couple mason jars Pyrex Dish Fan Good Ventilation A device to decant such as eye dropper, pipette, syringe A LOT OF TIME - jungle demands patience for full completion Procedure: The Toluene is nasty. Use all your usual safety procedures such as long sleeves, goggles, respirator, gloves, etc, extra fans, extra precautions regarding flames or sparks in the area Warming the Toluene may increase yield. i usually go ahead and warm it by pouring hot tap water into a pan then placing a small mason jar with Toluene in it. i change out the water for new hot water every 10 mins. and warm for 30-40 mins. 1.) Add 40-60 mL of Toluene to your spent mimosa. Seal and rock gently for 5-10 mins. Be gentle - rock, don't shake. Extra time pulls extra material. Good things are worth waiting and working for . . . . 2.) Let the material in the jar separate. This may take longer than it did for your initial naptha pulls. Check every 15 mins. Should be ready in 45-60 mins at the absolute max. 3.) Once you have 2 layers, decant (suck off) the top layer into another, clean jar. 4.) Repeat Steps 1-3 three more times, collecting all of the Toluene into one jar. 5.) No do a second decantation by carefully pouring the Toluene into your pyrex dish, leaving behind any mud (MHRB), oils, emulsions, etc. Just get the Toluene. 6.) Place this pyrex in a sealed room under a window with a small fan set on High. Stuff a towel under the door. Check every few hours. This will take most of the day. You cannot freeze precipitate with Toluene so you literally must evaporate it all. 7.) You are going to get an evil looking oily or greasy residue that can easily be any of these colors: yellow, orange, red, pink, brown. Keep the fan on this residue for a couple of days, yes DAYS. You can remove it once all the visible liquid has evaporated. 8.) You are going to be completing the evaporation over a period of weeks. After a couple of days you can take the fan away, but you are going to want to cover the pyrex in such a way that evaporation can happen, but dust, animal hairs, small mites, etc. do not get into it. i usually just loosely lay some paper towels on top. 9.) Check every few days or so. What you are looking for is for that greasy residue to change into neat looking wheels of crystals. They will still have the weird color(s) but they should be clearly crystals with an overall shape of a sea anemone. This is a flat kind of smear of crystal (sorry, no pic to attach at this time). 10.) Once the crystals have been achieved and you take a good whiff and smell something weird/interesting but no real solvent - now you can take a razor blade and start scraping up the now-waxy goo. Scrape and chop. 11.) Continue to scrape/chop/dry for another week or two. You now have Jungle Spice ready to use. This stuff is HEAVY. The body load is heavier than straight freebase IMHO. Positively paralyzing. Also, i am finding the typical user is easily breaking through on 25 to 35 mgs of jungle, correctly vaped, rather than 40-65 of the freebase. Finally, yes, you CAN make this into changa. Use the same procedure to make changa, just understand that the jungle will be more stubborn about going into solution, so you need to mix aggressively. Enjoy!
