>>>Aeroplane Brand Tamarind Slab (Imli)
This fruity-sour seasoning comes from the large broad bean pod of a tropical tree native to India. The brown pulp is scrapped from the pods, dried and sold. It is also refered to as Indian date, and can be bought here in many forms: raw, powder and concentrate. Raw tamarind must be boiled and squeezed through a sieve. (Be sure to discard all fibers, skin and seeds before use.) Tamarindus indica.

But as you can see, they say they have it in raw, powdered & concentrated.
Of course, I'm assuming this is NON organic (and as such would probably be laden with toxins -especially in India-) but at this point, I'm FAR more concerned about the fluoride.
I'm gonna keep looking, but this looks like a decent start :)
