from another thread here: quote from Salvinorin A: Now what's interesting to me, as someone brought up on the E-Dot forums... This extraction technique (techinque is not specified but were discussing salvia tinc.)has a very interesting segment.. "If at all possible use 190 proof alcohol to dissolve the dark colored waxy extract because higher proof alcohol will make it tincture more effective. Also, the dark chlorophylls from the extraction will make the tincture far more effective than without it, because the wax both increases the amount of Salvinorin that alcohol can hold and also increases sublingual absorption of Salvinorin." It states that the dark impurities are better for sublingual absorbtion?? Hoowhat??? It was always SWIM's impression that the less impurities in the solution, the easier it would be for Salvinorin-A to cross the membrane. Has You ever tried this? the differnece between a clean and impure sublingual absorbtion? Because it is definitely peculiar. this dosent sound right to me at all,how would the wax help with absorption?
