When someone has had candida for a long time, the immune system is totally overwhelmed and gets used to you having candida. It sort of gives up trying to kill it. The point of immunized eggs or colostrum is to switch the immune response back on again, thus encouraging the body to attack the candida itself. Some alternative doctors advocate injections of candida to quicken immune response in the recipient.
I do see the point of using anti-fungals at the same time though and am going to have a go with Colloidal Silver .
