Thanks for your response. I may just keep on guessing. I borrowed the Save Your Life videos and watched them all. (I don't have a TV, so I also had to borrow one of those with a VCR in it). On the video covering tinctures, Dr. Schulze does encourage people to just go ahead and make their own, even if guessing. I didn't get to see the Save Your Life manual, and there are probably recipes in there - maybe I'll run across someone who can lend it to me.
