first of all, if using acacia, rootbark is not usually a sustainable option for harvest and will usually kill the tree (with australian acacia). i take it you imported confusa though?
if you've already extracted the dmt in the naptha but pulled fats as well, prepare a solution of ph4 water and mix it with the naptha. This will pull the dmt into the acidic water and convert it back into a salt. do this a few times, as the first lot of acidic water likely won't get all the dmt out. Don't do it with warm or hot water otherwise it will pull the fat too .. make sure both are room temp. You can use white vinegar without water.. though the dmt doesn't want to be in too strong an acidic solution for too long.. so you'd wanna rebasify it quickly. once you've rebasified the now dmt containing acidic water, you can just pull again with naptha and it should precipitate or evap to a nice white crystal
