Low oxalate diets?

[yssie]

I''ve recently found out that two people close to me have been put on low oxalate diets - one for kidney stones, the other for some other rather more complex issues. Both are missing chocolate and black teas, and I''d like to put together little gift baskets for them, does anyone have any thoughts on low-oxalate white chocolates, teas, and candies (and where to get them!?)

Thanks!!
