The Mazatecs of Central Mexico use this herb only with a clear intent and purpose. It is always used under the supervision of an experienced shaman. It is used this way for good reasons. Since Mazatec shamans are probably not available to guide you through your own Salvia divinorum experiments, it is essential that you thoroughly educate yourself before deciding to work with it. Talk to others who are already experienced with its effects, read books, and read the information available at the Salvia divinorum Research and Information Center.
