Schizo, ginkgo biloba  from Das Racist – Puerto Rican Cousins
Lyrics on Rap Genius   Schizo = Schizophrenia  Ginko biloba is a
type of tree, grown mostly in Japan and China. Its been used to
make medicine that aids patients with dementia and Alzheimers,
which is either what Heems is referring to (which wouldn’t be
that clever) or this is just a non-sequitur (making it Dadaist
like the previous line).  Oh yeah and ginkgo biloba is strong as
fuck, too: it was one of the few living things left in Hiroshima
after the U.S. dropped the atom bomb.  To help improve the
