How do you do a clay bath without ruining your plumbing? Won't the clay gum up the pipes?
How do you do a clay pack? What I do is wet some Bentonite and then a wash cloth, and fold the washcloth in half. Over that I place a folded wet paper towel to keep the cloth from getting dirty. Then I cut some cheesecloth to fit the folded washcloth, unfold it, lay 1 layer on the cloth, put some clay on top, and fold over the rest of the cheesecloth so the clay is like meat in a sandwich. The cheesecloth side goes over the neck and is held in place with plastic.
As far as adding herbs are concerned, I've tried them and they don't work. It seems to gum up the works. The clay works best alone.
