How is Salvia divinorum consumed?
Most ethnographic accounts state that the Mazatecs make an infusion by rubbing leaves together and squeezing the leaf-juice into water. A couple of reports state that the leaves were first crushed on a metate (a flat stone). One ethnographic report described the preparation of a dose by merely piling up the leaves in pairs, face to face, and then rolling them into a cigar-shaped bundle, chewed, and swallowed (Blosser 1991-1993 in Ott 1999). Unfortunately, as far as a “dose” goes, the available ethnographic data usually relates the number of leaves used per dose (frequently stated as so many “pairs” of leaves, due to the Mazatec penchant for counting them in this manner). Such information may not be too useful because leaves can vary quite a bit in size, with some leaves being five or more times the size of others, depending on growing conditions, and the potency of leaves can also vary dramatically from plant to plant.
