Here we grind up the propolis (previously cooled down) and soak it in
100% ethanol (can be pharmacy grade grain alcohol) for several weeks, mixing
once a day (or constantly with a machine).
Normally 30 g of propolis are used per 100 ml of alcohol.  At the end
the solution is filtered.  It has to be kept capped to prevent the
alcohol from evaporating.
This solution becomes a suspension when mixed with water, when someone
is going to drink it.  We use it pure on wounds, though some prefer
10 or 20 gram solutions.  It works well on skin fungus.
