Has anyone made a Pau D’Arc tincture? It is a bark from Brazil I believe and I’m not certain of the oil content. My Dr. in Mexico has prescribed this for us, he is an MD turned Natural Remedies Dr. I want to make the tincture using a 40% Alcohol. My reason for the tincture is that we are drinking a lot of another natural product during this treatment and it would be way too much to drink the Pau D’Arc as a tea.
