Part of the reason why we don't need to reach the full doses is because with Buhner's, he states that you are changing the terrain of the body - building up the body's own defenses so that it can conquer the infection(s) on it's own, with a little help with a couple of anti-spirochete herbs.
I would add though, that if you can get up to the 'full doses', I would encourage it. You want to be sure that these infections are being treated well.
