Yopo
Yopo is a powerful psychedelic snuff made from the seeds of the Anadenanthera peregrina tree, used for centuries by indigenous peoples of South America and the Caribbean. It contains potent tryptamines — primarily bufotenin, DMT, and 5-MeO-DMT — and is traditionally blown into the nostrils during shamanic rituals for healing, divination, and spiritual connection.

Description
Yopo has been used for at least 4,000 years, with archaeological evidence found in burial sites across Venezuela, Colombia, and the Caribbean. The seeds are harvested, toasted, and ground into a fine powder, then mixed with an alkaline substance (traditionally calcined snail shells or tree ash) to make the active compounds bioavailable. It is blown into the user's nose by another person using a long tube, as the intensity of the experience makes self-administration difficult. The effects come on rapidly and intensely — typically within minutes — and include vivid geometric and entity visuals, a strong bodily sensation, and a profound shift in consciousness. The experience usually lasts 20–45 minutes. In traditional Amazonian and Orinoco Basin cultures, yopo is used by shamans (known as curanderos or payés) as a diagnostic and healing tool — to communicate with spirits, identify the cause of illness, or receive guidance. It is rarely used recreationally in its cultural context; it is considered a serious and demanding medicine that requires experienced guidance. In recent years it has gained attention in Western psychedelic research and wellness circles, though it remains far less studied than ayahuasca or psilocybin.
