We've been using Andrographis for about 3 weeks now. It got my son out of a really bad exacerbation triggered by the flu. Has anyone else used it and what was your experience? I first heard of it in a post in one of these forums on latitudes but haven't been able to locate that post. I can't say enough good about our experience with it. The only side effect I've noticed is that in lowers blood sugar, so I've been giving my son a low dose of Chromium Picolinate, as well. I'd like to compare notes with others on this.
