" The healer's job has always been to release something not understood,to remove obstructions (demons, germs, despair) between the sick pa-tient and the force of life driving obscurely toward wholeness. Themeans may be direct—the psychic methods mentioned above—or indi-rect: Herbs can be used to stimulate recovery; this tradition extendsfrom prehistoric wisewomen through the Greek herbal of Dioscoridesand those of Renaissance Europe, to the prevailing drug therapies of thepresent. Fasting, controlled nutrition, and regulation of living habits toavoid stress can be used to coax the latent healing force from the sick body; we can trace this approach back from today's naturopaths to Galenand Hippocrates. Attendants at the healing temples of ancient Greeceand Egypt worked to foster a dream in the patient that would eitherstart the curative process in sleep or tell what must be done on awaken-ing. This method has gone out of style, but it must have worked fairlywell, for the temples were filled with plaques inscribed by grateful pa-trons who'd recovered. "
