what do they process the urushiol for??
Best I recall, the oil was extracted from cashew shells, where it's found in extremely high concentrations, for use in brake linings. Can't remember in exactly what capacity.
Cashew shells? So you're telling me that there's no market for wild-grown poison ivy??

And here I thought I might be sitting on a small fortune....

Thanks for the info Yolk, that's interesting stuff.
