About this resource
This is not a full translation of the book chapter. It is an independently written detailed introduction based on the public book PDF, publication information, and chapter abstract, organizing its scope, analytical concepts, relevance to Hapé/Rapé research, and limitations. Rapé and sananga appear directly in the title, but the chapter is not a pharmacologic study of 1 substance. It discusses multiple “forest medicines” within village–city networks expanding around ayahuasca (nixi pae/uni).
Rapé, sananga, kambô, and ayahuasca are not the same. The chapter examines how urban rituals and exchanges place them in the same category, while their constituents, routes, hazards, and cultural authorities remain different. Terms such as “medicine,” “healing,” and “science” are treated as categories translated between village and city, not as proof of biomedical efficacy.
Study design
The chapter anthropologically examines movement between Pano peoples in Acre—particularly Huni Kuin (Kaxinawá), Yawanawa, and Noke Kuin (Katukina)—and non-Indigenous urban participants and religious or holistic spaces. Its scope includes contemporary village practices, references to earlier times, cultural presentation in cities, ritual networks, and the translation of concepts that occurs within them.
This was not a questionnaire study using a random sample or a clinical trial. Drawing on the author’s ethnographic research and relevant literature, it interprets changing relationships between villages and cities. Without participant counts, comparison groups, exposure amounts, or diagnostic indicators in a quantitative design, the existence of meanings and practices must be distinguished from estimates of their frequency or effects.
Content
At the chapter’s center is the movement of Huni Kuin, Yawanawa, and Noke Kuin people presenting culture and ritual in urban holistic spaces, suburban facilities, Santo Daime churches, ayahuasca-religion venues, and private homes. There, rapé and sananga are not understood only in isolation; they are repositioned as mediators of human and ritual networks created around ayahuasca.
Rapé is broadly distinguished as a combination of tobacco powder and plant ash, while sananga is distinguished as a plant-derived liquid used in the eye. Defining product specifications, however, is not the chapter’s purpose. The analysis focuses on who transmits knowledge, from whom it is received, how village meanings become different words in cities, and where concepts such as “forest,” “spirituality,” “healing,” and “medicine” overlap or diverge.
Results
The chapter depicts not a 1-way “export of tradition,” but a process in which practices and categories move back and forth through Indigenous and non-Indigenous contact, producing new meanings and forms on both sides. Grouping them as “forest medicines” in cities may increase visibility and political or cultural value, while also risking simplification of differences among each people’s knowledge, constraints, hazards, and materials.
Rapé and sananga are discussed not merely as commodities transported from village to city, but as mediators connecting relationships, authority, knowledge, and cultural presentation. The contribution is an anthropological understanding that urbanization and circulation involve translation and reorganization rather than preserving culture unchanged. It does not provide symptom-improvement rates, disease-specific effects, or pharmacologic mechanisms.
Limitations
The chapter is an interpretation centered on 1 region and network and does not represent all Indigenous peoples of the Amazon or every rapé product now on the market. Within “Huni Kuin,” “Yawanawa,” and “Noke Kuin” there are differences by generation, village, role, and political position, and speech made visible at urban events cannot be assumed to represent consensus across an entire people.
The chapter did not measure tobacco species, ash species, pH, total nicotine, free nicotine, TSNAs, or PAHs in rapé. It did not test botanical identity, concentration, or ophthalmic outcomes of sananga in a comparative trial. Because multiple substances are discussed through an ayahuasca-centered network, cultural reports about 1 cannot be transferred to the effect or safety of another.
Safety
Calling something “medicine,” “healing,” or “cleansing” within a culture does not clinically guarantee product quality, efficacy, or safety. In rapé, tobacco, ash, and other plant composition and nicotine exposure may vary by product. Sananga is a different preparation contacting the eye, and findings about rapé cannot be applied to it. The chapter was not designed to determine adverse-event rates or a safe amount.
This resource gives no procedure for ritual participation, preparation, administration, or self-treatment. A label of village origin or authority conferred in an urban ritual should not by itself be used to infer safety, authenticity, or consent by an Indigenous community.

No DOI was assigned to the chapter, so no DOI appears in the frontmatter. The authorship, chapter title, editors, publisher, and ISBN were checked against the public book PDF and university publication information, but no clear chapter-level reuse license was identified. A full translation was therefore avoided, and this page presents the research scope and arguments in independent wording.
