Viral /yeast/metal and deficiencies

[Guest guest]

I know read it somewhere around here before, and I hate to go twice around a

subject, but hangnails are a sign of what deficiency? And under-eye circles as

well?

Also, do viral, yeast and metal issues all produce the same symptoms in ASD - if

not, is someone able to give me a quick run-down on the differences? I'm trying

to google here....but all it's bringing me to is " causes " grrrrrrrr
