Freeze precipitation will not work with xylene or toluene. Your toluene/xylene pull should look piss-yellow. Evaporate this stuff and you will get red/brown oil mixed with yellow/white crystals. Scrape it all up when it is reasonably dry and put it in a small glass container, like a test tube. HEAT some heptane (bestine) in a water bath until it is hot to the touch and add it with a dropper to the material from the toluene pull in the test tube. HEAT is essentil for this process. The red spice is not soluble in the heptane, so you want it to MELT so all the DMT can be released from the solid chunks, and the insoluble oil wil settle at the bottom. If this does not happen, place the test tube in the hot water bath until it does. You should see two VERY defined layers, a red oil on the bottom and of course the heptane/DMT layer. If the bottom layer is yellow, just siphon off the Heptane layer for evaporation and add more hot heptane to the test tube, always keeping it hot. Cap the tube and shake it up. You want the oil to be melted and you want to mix the layers as much as possible and allow them to separate again, always in a hot water bath. Repeat this washing process as many times as needed unti lthe bottom layer is dark red. Siphon off the heptane for evaporation and then pour off the red oil on a plate and let it dry. This the red jungle spice, and I cannot seem to purify it any more beyond this. It is the greatest stuff I have ever consumed, and if we can get all the DMT OUT of this product, it is a LEGAL PSYCHEDELIC from a NATURAL SOURCE. I personally LOVE the idea.... "sorry officer, this is a legal herbal product!" Oh BTW when you evap the heptane from this process you will get a shitload of DMT that would have been left behind in the basified solution.
