Colloidal Silver: I totally cannot live without this. I use it for everything: mouth wash, anticeptic internal and external on cut, spots, open wounds, insect bites, wiping down toilet door handles, light switches, cleaning remote controls, mobile phones, pc keyboard. I use it in tap water both for myself, when I have to drink tap water, and also in my dog's water. Colloidal Copper: I use this all the time as an antibiotic, anti bacterial agent on myself or dogs. I also use it on open wounds, cuts, grazes and stings. There was a time when i used to get Impetigo every year, but since using Collidal copper, silver and gold, which I spray onto the affected areas if I feel it coming on, It never get's any worse. This stuff stops it in its tracks. I use it, drink it, when i have cold, or chest cold, of which I have only had one of in 3 years, the copper also stops a chest infection from taking hold too. Especially important to take it, since no one will give you antibiotics these days. But, guess what? You don't need them now, now when you can use these colloidals. Colloidal gold: Cannot live without this either. I use it well, for all of the above but mostly for joint pains, in particular, osteoarthritis. Without this, I am in constant pain.
