I use Colloidal Silver nearly a year for different kind of things. Over 50 I don't take any medication. I had some problem with my heart but doctors could not find out what. I don't trust in doctors and don't want to take anything if that is possible. I was searching for natural alternatives when I found Colloidal Silver. First I wasn't sure about it but I thought just try with a little jar. Helped me with my skin problem (acne). Doctors coudn't. Use it internal and external since. Little spray bottle is always with me. My daughter asks me if she's got some problem what to do? Always say to her first try Silver. In the beginning she looked at me strange and I think she thought I lost my mind. Now when I say to her the answer is I do it already. I can recommend to everyone. The costumer service is great. Alan helps me if I have a question. Thank you for the service and the product
