The two types of tinctures I have some experience with are ethanol based (using Everclear) and glycerine based ones using food grade glycerine / glycerol. If using glycerine you must let the herbs sit in the liquid for about a month in a cool, dark space and shake the container daily. Ethanol extraction is much quicker, usually only about 5 minutes, certainly less than one hour where the herbs are shaken in a solution of as high a percentage ethanol (pure grain alcohol) as possible. Then the herbs are filtered out of the liquid and you have your tincture at the end. Personally I find the glycerine based tinctures to work better. The ethanol seems to pull some unwanted tastes and colors out of the herbs and the glycerine seems to pull less of these. The added benefit of the ethanol based tincture is that if you want a smokable material as well you can just evaporate the ethanol, scape up and smoke or vap the remaining resin. If this is your goal (honey oil or hash oil or shatter glass hash) there are much better solvents than ethanol. You want a non polar solvent like Hexane that evaps cleanly. Many people use Butane, but i've hear enough stories of contaminants in the butane and people not properly purging their final material or using unsafe extraction vessels like PVC or plastic or galvanized steel or the like that many people are making a poisoned product instead of a medicinal one.
