This weekend I worked on a tincture (in a glycerin base) for a friend of mine. In this 4oz tincture bottle, I started with about 3oz of glycerin and 1.5 oz of water mixed together. I always use a little more because the herbs often soak up enough that if I use exactly 4oz, it doesn't end up filling the bottle. Into this, I added 1 tablespoon each of Lemon Balm, St John's Wort and Gingko and 3/4 tablespoon of Licorice root (based on James Duke's recommendation). I let it steep in the double boiler about a half hour and then strained it into the bottle with a nice dropper so she can either put it directly in her mouth or add it to water, tea or juice.
One advantage of working in hospice is that I get to play with all the therapy dogs. This is Asher, a Corgi.
