Did you mean Lapacho (Handroanthus impetiginosus) sometimes also called Pau d'arco? I have used it, I drank it as a tea from time to time as I happened to like its taste. I don't think I derived any benefits from it as I wasn't taking it for that purpose but It is supposed to have many properties including cancer healing properties.
