Tincture recipes

I am making my own tinctures, and having a great time of it. I am getting the Dr. Schulze recipes from Tom Harrelson's website, http://healingtools.tripod.com. Because of copyright restrictions from Sam Biser, he had to remove a lot of recipes.

Does anyone know of another source for tincture recipes? I just made the digestive formula using my own guess as to proportions. I felt comfortable doing that because you really can't go wrong with ginger, peppermint & fennel. But I'm less familiar with many of the herbs used in other formulae.

I'd appreciate any leads.
