House and Vitamin Deficiency



Sorry to raise this here...

A friend of mine just told me she has had small cuts on the
tip of her tongue for a while now. Maybe a month or more.
It really hurts when she drinks grapefruit juice.

I suggested she see an M.D. But no, she wasn't going to
do anything, but she saw on an episode of House
that some vitamin deficiency might be the cause.
Of course, House said IT WAS THE CAUSE!!

Now, this sounds just as cuckoo to me as it does to anyone
reading this and I know House has practically NO legit
medical advice. But, tomorrow she wants an answer.
I know she wants some justification for what some
might call Homeopathic treatment. I don't know what to say.

Is there anything to this? I couldn't find anything during
about 1 hour of searching the 'net.

thanks for any help...thehick
