This study presents the influences that structure the Neo-shamanism practiced by Brazilian naturologists trained at the University of Southern Santa Catarina, a system they emically call «Shamanic medicine» or «Shamanic cosmology». 74 hours of interviews were conducted with the creator of this system, as well as with 18 other Brazilian naturologists or naturology professors. Based on these interviews, four sets of influences were analyzed: (1) strong influences: religious goods directly transplanted into the practice of naturology; (2) weak influences: punctual experiences of the founder that impacted this form of Neo-shamanism; (3) invented tradition: alleged influences that have no concrete connection to Shamanic medicine in Brazilian naturology; and (4) parallel influences: religious exchanges made by naturologists that have reflexes on their form of Neo-shamanism, but that are discouraged or disregarded by the creator of this system. A strong influence of New Age esotericism and the Rajneesh Movement was observed, to the detriment of weaker influences of the traditional Peruvian, Ecuadorian, Navajo, Cherokee, and Apache Shamanisms. A lineage of Mapuche Shamanism was alleged, but wasn’t attested to in the naturologic practices. Finally, parallel influences of Guarani Shamanism, Santo Daime, and the Red Path were attested to among many naturologists, but discouraged or disregarded by the creator of this Neo-shamanic system.
