Interestingly enough, the magic butter machine’s, “Magical Tincture,” says not to add lecithin but all the others say to add it, like the butter, food oils, even milk all say to add the lecithin to make the onset quicker, except the ethanol based tinctures which say to use 151 grain alcohol minimum and 190 grain alcohol maximum.
Emerald 151 grain is what I used for my last batch of tincture.
