I have bought the Sam Biser'course and there is a lot of information in it. There are a lot of things, "how to prepare tinctures, decoctions poultice etc.
It would be interesting on your web site to know how to prepare a tincture and not just where to buy them. You can make a lot of tincture by yourself and save a lot of money.
But I guess you can't, because Mr Sam Biser don't want anybody copywrite his course. (This is ridiculous) I guess Mr Biser is more interesting about money than to make people getting well.
Anyway I have his course and if you have any question about the preparation of tincture or anything else, write to me again on this forum.
