Tincture with 4 herbs
I am being asked to make a water/glycerin tincture with several herbs. I am some what confused on how to do several herbs… Do each herb extraction is 1:2 or 1:3 etc? Do I do each herb extraction separately in a water/glycerin solvent. Afterwards doing 4 herbs tinctures do I combine the a portion of the extracts to make a final result?
