Jason, Thank you for your reply with so much information. My boyfriend does intend to take silver orally first. I just wondered why the MSP seemed to be considered different from all the rest. >From your response, I get that it's due to the high concentration. I have seen some colloidal silver in healthfood stores that are 400 to 500 ppm concentration. So would they be considered unsafe also?
Oh yes, what exactly is the herxheimer reaction? Is that due to too many pathogens dying off at once? Or something else? It's hard to know which product would be best to start with. >From all of my reading, I'm thinking about Meso silver which claims to be 80 percent colloidal and 20 percent ionic. Summer
