ow man, sierra mazateca isn't salvia divinorum at all, it's the place where it is cultivated by, as the name says, the mazatec indians (in fact the name mazatecs isn't ethnical completely right but wtf).
it's a mountainous place in the south-western (?) corner of the state oaxaca in central mexico.
they grow skha pastora and have a ceremonial use when their beloved teonanacatl is scarce.
those people are are one of the headsources of mushroom, salvia, morning glory and woodrose use
but you already did smoke salvia, no?
Yante'e !!! (Bye in mazatec.)
