While not quite the same thing, this reminds me of that time when tramadol was found in tree bark in Cameroon and misclassified as a natural product for a while: > [You] can indeed extract tramadol from the stated species – there’s no doubt about it. You can extract three of its major metabolites, too – its three major mammalian metabolites. That’s because, as it turns out, tramadol is given extensively to cattle (!) in the region, so much of it that the parent drug and its metabolites have soaked into the soil enough for the African peach/pincushion tree to have taken it up into its roots. http://blogs.sciencemag.org/pipeline/archives/2014/09/15/weirdly_tramadol_is_not_a_natural_product_after_all http://blogs.sciencemag.org/pipeline/archives/2014/09/15/wei...
