Their colloidal silver is ineffective. Get Sovereign silver's hydrosol instead. Listen what they say about colloidal silver. Never trust a site that only post the reviews they want you to see. I made post about my true experience with them and they would not post my comment. Earth Clinic's colloidal silver isn't even positively charged. Do not waste your money for yellow water.
Tip for consumers: check out sovereign silvers page, I used their hydrosol to get rid of candidiasis. It worked! earth clinics did not!
