Does this therapist also try to sell the group members these tinctures? It sounds kind of iffy to me, especially how she put the tincture in the group member's water buttle. I just wonder if she is making some money from selling this stuff.

Yes. The group is not your cup of tea. You didn't know how it would be. There should have been better disclosure about the important role the homeopathy would play. Do what is best for you. The "higher power" talk sounds like AA or NA. Is it a recovery group?
