This high-potency Colloidal Silver is made from my own distilled water in a small lab, using only the finest, high-grade 99.99% pure silver. I offer two consistencies, 19 ppm and 30 ppm, so you get exactly the potency you need. Use it as an all-around detoxification and viral protection liquid, both for ingestion and as a topical antiseptic. Many also use it as a gargle for mouth and tooth infections. Experience the power of Colloidal Silver today by buying it from Noah's Ark Healing Center in Cornville, Arizona. With just one purchase, you'll feel the difference in your body!
