Subject: Looking for any medical research that involves any part of a walnut tree.

I am a published author working on a science fiction novel. I would 
like to include some type of medical cure derived from a walnut tree 
in my lastest book. I don't need the cure, just some ideas from which 
to draw some plausible inferences for future discoveries. I've done 
some research already but am coming up dry. Any ideas?
