Banisteriopsis caapi :: Botany

Banisteriopsis caapi "It was thirty minutes before I felt the first sensation, a numbness on the lips, and a warmth in my stomach that spread to my chest and shoulders even as a distinct chill moved down my waist and lower limbs...I opened my eyes to a flash of light, a passing headlight on the road, harsh and intrusive. I retreated again and felt myself fade into an uncomfortable physical body, prostrate on the mat, and tormented by vertigo and a mounting nausea" (Davis 1996). This account describes the beginning feelings and affects of an experience between Wade Davis and yage, a drink whose main component is the plant Banisteriopsis caapi. Banisteriopsis caapi is a plant found in the tropical regions of South America, including the countries of Brazil, Ecuador, Peru, and more. It is a liana that grows in the tropical forests of these regions and is often utilized in native tribe cultures. Many different aboriginal tribes of the Amazon rainforests use drinks prepared from this plant under many different names: ayahuasca, caapi, yage, yaje, natem, datem, pinde, dapa, and more. It has been used in various tribe cultures for years and still has a place in today's societies and religions. Banisteriopsis of the Malpighiaceae, is a genus of around one hundred species of plants in tropical America. Three of these are known for their hallucinogenic affects in ayahuasca. These three plants are B. inebriens, B. caapi (Schultes 1970) and B. quitensis (Schultes 1995). The best known of these three species and the main component of ayahuasca is B. caapi. When the drink ayahuasca is made, it is often supplemented with other plants that provide hallucinogenic properties to the drink. There are many species of plants, stretching across genera, that are added. Some of the plants included in these various admixtures are Diplopterys cabrerana, Psychotria viridis, and Psychotria carthaginensis. There are also members of the Solanaceae that are commonly used, Nicotiana species, Brugmansia species, and Brunfelsia species (Schultes and von Reis 1995). These plants bring different chemical constituents to the drink. The chemical components of Banisteriopsis caapi that cause the hallucinogenic effect are beta-carboline alkaloids found in the bark. More than nine alkaloids have been isolated in B. caapi. The three main active constituents, and most well known from this plant, are harmine, harmaline, and tetrahydroharmine. Other beta-carboline alkoloids include harmine-N-oxide, harmic acid methylester, harmalinic acid, harmic amide, and more (Kawanishi et al 1982).
