its doing good things for your knees? thats great, i wouldn't have thought it would address that issue, very interesting. i do believe that the original forumula called for just the 4 herbs, but that doesn't mean it cant be improved upon.
someone posted a very interesting post that supposedly had the exact forumula in it, which Caisse had kept secret her whole life but i can't remember where that post went to. i'll see if i can find it.
i've been eating fresh burdock root lately in my salads, yummmmmy!
