Do you have a source for the assertion that tea contains fluoride?

The only way it could would be if Fluoride was present in the
soil where the tea was grown.  Actually, that makes sense in light
of Marilyn's post which mentions that there are exceptionally high
levels of natural Fluoride in the water in India... most tea 
consumed in the west is grown in India.  But I drink mostly
Chinese tea, so I guess I'll have to get my Fluoride elsewhere!
