If someone were to notice incipient blueness at the base
of the fingernails, what should that person do? There are
several possibilities.

1. Stop taking CS for a while.
2. Reduce CS intake.
3. Bind the ingested CS using methods described in a previous thread.
4. Switch to an alternative element.

In the latter case, the alternate might depend on the
particular health problem. Gold, zinc, copper, manganese,
indium, etc., etc., are all possible candidates. 

Has anybody considered which alternates deserve
priority?

Best regards,

Matthew
