Yopo (Anadenanthera peregrina (L.) Speg. Fabaceae)

Anadenanthera peregrina (L.) Speg., known as Cohoba or Yopo, is a woody plant of the Fabaceae family native to South America and the Caribbean. Indigenous cultures have used it in shamanic and religious ceremonies and as a diagnostic tool in traditional medicine. Its psychoactive effects stem from tryptamine compounds including DMT, bufotenin, 5-HO-DMT, and 5-MeO-DMT, which have significant hallucinogenic properties. This chapter describes the plant's botanical characteristics, historical uses, chemical constituents, pharmacological activities, and toxic effects.

Abstract

Anadenanthera peregrina (L.) Speg., sometimes called Cohoba or Yopo, is a plant species that falls under the scientific classification of the Fabaceae family under the Fabales order in the plant kingdom. It belongs to the Anadenanthera genus. This woody plant may grow to a height of 27 meters, forming various shapes, from small shrubs to massive trees. Anadenanthera peregrina (L.) Speg. originates from South America’s tropical savannahs and semi-deciduous forests and many Caribbean islands. It has significant cultural and historical significance to Indigenous groups, who have used it for many reasons, including shamanic and religious activities. In traditional medicine observed by Indigenous communities, Anadenanthera peregrina (L.) Speg. has been employed as a diagnostic tool to determine the cause of diseases and gain a deep comprehension of their fundamental origins. Anadenanthera peregrina (L.) Speg. has historically been used by Indigenous cultures in South America and the Caribbean to perform ceremonial ceremonies and participate in magical-religious activities. The psychoactive effects of Yopo seeds are mainly due to the presence of potent chemicals such as DMT bufotenin, 5-HO-DMT, and 5-MeO-DMT. These chemicals are classified as tryptamines and are recognized for their significant hallucinogenic properties. Indigenous cultures have historically used Yopo for several reasons, including medicinal and shamanic rituals. It has many pharmacologically active chemicals. The objective of this chapter is to provide a comprehensive account of the Anadenanthera peregrina (L.) Speg. plant, including its botanical characteristics, historical use, chemical compounds, pharmacological activities, and toxic effects.
