Is the fact that one's silver necklace tarnishes when worn next to one's skin a sign that one ought not to use colloidal silver? Thank-you.
It isn’t unusual for silver to tarnish when in contact with the body. It can even tarnish in the air, especially in humidity.
So, no it isn’t an indication for not using it. Now if you have an allergic reaction to wearing silver jewelry, then it could be you shouldn’t consume it.
