swim would definetly agree salt precip is the way to remove jungle its important to do it with as minimal amounts of vinegar (acetic acid diluted) has purified the vinegar with freezing it and removing the water before but its as easy not to. here this is off site but explains it swiftly
http://www.ehow.com/how_...reeze-distillation.html. jungle: has never bothered to crystallise this stuff but it does make a dark red resin that almost looks black post boil (the acetic A). it was found that boiling ur acid is not quite as simple as people try to make out you can boil it heavily but it does effect the end product slowly does it. the resason i say this is because as ur boiling away it will eventually need swirling to keep dissolving what is i assume freebasing like sulphur round a volcanic lake thats slowly boiling away. the freebased chemicals have much lower boiling points than the salts and so it makes sense to be as careful as possible. there has been alot done a fair bit too much to type in this one message.
views on jungle spice aka jungle: its very nice, a very heavy lethargy feel and is incredibly hallucinogenic (especially if no naptha pulls on the mash are done,leaving the nn dmt in it, another reason to go slowly on the boil).
its very much centred in the earth and not cosmic like dmt but still incredibly hallucinogenic. jungle lethargy if you are connected to the ground is really nice too, would definetly be suggested lying around on a nice day in the forest with a mate smoking jungle.
xylene: it would be best to associate yourself with xylenes safety data sheet here:
http://www.osha.gov/SLTC.../xylene/recognition.html that tells someone anything they could want to know except very specific things.
xylene carrys allot of junk it could be imagined from the mash oils that perhaps arent wanted its not known to be evaporated that does sound quite hideous n is pungent. best to salt and have another layer between lungs and xylene ? its possible though.
hope that helps.
