I have heard some people say that taking fairly large amounts of CS has helped
darken their gray hair. It is also my understanding that fingernails are
basically the same as hair, only wide and thick.

I have experienced what I might term fingernail argyria after taking large
amounts of 80% ionic/20% colloid 5 ppm CS.  After reducing the dosage to only a
few ounces a day, instead of a couple of quarts a day. It is no longer forming.
Unfortunatly when it first appeared at the base of the nail in the area that is
normally white or light colored, I was looking for a medical problem such as
poor circulation.  However now that it has grown out beyond the white area and
the white area has returned to white, I now realize it is a stain inside the
nail itself, and will eventually grow out and be trimmed off.

Does anyone else have any information on this.  Does this mean that although
silver is not normally retained by tissues, that is can be in newly formed
tissues?  Would that make one more susceptible to argyria if they get sunburned
and new skin has to grow to replace the burned skin?

The attached picture does not show the effect very well. The darkened area near
the base is much darker than the picture shows in reality.  It seems that the
flash washed the color out of the blue area.
