Hello,

I heard about a case of contamination of a drug (levostreptofan) in the '90 that created
catastropical neurological consequence for a couple of persons. I'd like to
read more on this. I searched Google and found absolutly nothing for
"levostreptofan" or any other gramatical variation that I tryed. I'm pretty sure my
spelling is wrong and maybe badly! I just heard the word, never saw it. Did you heard about
something similar to this name. I know very little about this and it could
even be a natural product.

Thank you very much for your help.

Yannick
