the aztec entheogenic complex is extremely well documented. through historical evidence, there is proof that the aztecs used several forms of psychoactive drugs. these drugs include ololiuqui (the seed of rivea corymbosa), teonanácatl (translated as “mushroom of the gods," a psilocybe mushroom) and sinicuichi (a flower added to drinks). the xochipilli statue, according to r.g. wasson, gives the identity of several entheogenic plants. other evidence for entheogenic use of the aztecs comes from the florentine codex, a series of 12 books vividly describing the aztec culture and society, including the use of entheogenic drugs.
