Fungal Candida produces far more waste than it cleans up. It produces alcohol like substances, ammonia, and inflammatory enzymes. Beneficial yeast in the gut does minimal cleaning while our good bacteria is mainly responsible for proper gut health. Fungal candida is designed to decompose matter so not exactly the type of cleaning that someone wants to experience.
Caution with Colloidal Silver because it has a good chance to interfere with good bacteria making it counter productive.
