i read down that until i saw a link to selenium deficiency. i also think Iodine is a big problem with these people as well.
you have to take a lot of silver for a long time. i took it for two years off and on, sometimes taking tons of it and it was thick, big molecules and all colors of yellow and into red. it has been three years since then and no blue.
this kind of feature is definitely a sign of lack of circulation. the guy probably takes coral calcium as well.
this does make an opportunity to say that CS should be done to treat something in particular and then be done with it. the total need int he human body is small and can be had with very infrequent use, either internal or external.
the guy thinking it is because of topical use is also off base. if it can get into the skin from the outside, it can get out.
but, like you said, whats the problem with being blue?
