Perelandra (Michelle Small-Wright's foundation)has a rather unique approach to this 'communication';they call it "microbial balancing" and it was formulated to answer to both humans and gardens. (They also have a unique view of what constitutes a garden). In general, I find the principles they are working with to be very sound.
I agree, on the Candida Forum , and actually, all around curezone, there is a suprising (to me) attitude of attack and defense; a war on parasites, and all that sort of thing that seems to be in complete contradiction to any grasp of wholeness.
