take 30g of peruvian torch, and make two boils of tea, throw in some lye water to basify, then shake the mixture around. add xylene or cooking oil. then salt out the mescaline with a vinegar/citric acid and methanol mixture. evaporate for mescaline salt.

2- citric or acetic and water-not alchohol/ to salt from np solvent
