The full moon is the strongest time to decant your herbal tinctures. That is a fancy word for straining them. If you have herbal tinctures that you made 2 new moons ago or earlier, it is time to strain if you are reading this on a full moon. Remember to thank the herb you are working with and to give the strained herb back to the earth rather than just throwing it out. You can charge your herbal tincture in the moonlight during the full moon before storing in a cool dark place.
