The Silver Hydrosol being made by MEINTU is worth the try for those of you that use silver. It has helped me greatly and I have used Sovereign silver and Mesosilver. The Human brand came out the gate and is running neck to neck with these manufacturers. It has helped me greatly with a severe sinus infection. I work in Hospitals and use it as a hand sanitizer as well, along with my daily dose orally. Spoke with Bill Ross Managing Director via email to give him my feedback on the product and to let him know that I'm very pleased. He informed me that a portion of the proceeds go to the greater Boston food bank. That I was very pleased to hear. The homeless in America is our greatest shame, these food banks help to feed children and families in need. But give it a try you won't be disappointed.
