Re: hmm he may be a jerk.

  Can't silver (Ag) be an antimicrobial even if it's rubbed on your skin, as they do in an emulsion for burns?

This is Silverdene, which is not pure silver.  It is silver sulfadiazine.  And yes, at a high enough concentration the silver does show antibiotic properties.  But again this is in a petri dish so it has a direct contact at a high concentration.  This is not the same as in the body.  Putting salt directly on bacteria would also kill a lot of bacteria, yet we eat salt and still get bacterial infections.  This is why in vitro (outside the body) studies are not of much use.

CS reminds me of homeopathy (is that why you don't like it?)

I don't see any similarities at all between CS and homeopathy.  Homeopathy works through resonant energy, while silver is a chemical reaction.

As I said before I think it is over priced and over hyped.  What few studies do exist are contradictory and only discuss the actions on bacteria.  Not on viruses, fungi and molds as the sellers claim.  And as I also pointed out in my last post there are too many unanswered questions.  For example, what is the effect of stomach acid on the silver?  If the silver is just going to form silver chloride then particle size to begin with should not matter as it is still going to form a larger particle that is more apt to get caught in the tissues.  We know a whole lot more about the safety, actions and effectiveness of herbs, which is why I prefer them over CS and even pharmaceutical drugs that we also know very little about.  If they can do the studies to answer my previous questions someday then I may be accepting of the use of CS internally.  Right now in my opinion taking CS internally is akin to going out in the forest and picking a plant we are unfamiliar with at random to treat a disease.  We really don't know anything about the safety, actions or effectiveness of the unknown plant so we would be ingesting it on faith.  Therefore if I use CS it will be externally until more is learned about it.

Not healing in vitro means nothing to me. Do herbs heal in vitro?

In vitro is outside a living organism like test tube or petri dish studies.  In vivo is inside the body.
