my second and third extraction from 500g MHRB went through a yellow naphtha state, which was washed several times with sodium carbonate. still as yellow naphtha i decided to evaporate and recrystallize, with light yellow colored resulting crystals. i supposed it could be fats, but after i tried the spice i got this really unpleasant burning sensation in mouth and lips. it became so annoying that i had to stand up middle trip to get some vinegar to wash my mouth, for i thought it could be lye residue, is it?
any response is greatly appreciated!
