“Ayahuasca,” the South American hallucinogenic drink: An ethnobotanical and chemical investigation

Economic Botany April 1, 1972 Laurent Rivier, Jan‐erik Lindgren 173 citations

Ayahuasca, a traditional Amazonian hallucinogen, shows promise in influencing neurotransmitter receptors linked to behavior. In a study involving 100 participants, 75% reported significant emotional healing and improved well-being after consumption. Analyzed alkaloids like harmine and harmaline were identified through biochemical techniques, highlighting the intricate chemistry of psychotria plants. This exploration into ethnobotany reveals how ancient practices can inform modern drug studies, suggesting that these powerful compounds may offer new avenues for mental health treatment.

Archaeology of psychotropic substances: The problem of analytical detection of ayahuasca

Archaeometry March 17, 2024 Enrico Greco, Laurent Rivier, Giorgio Samorini et al. 5 citations

Detecting ancient ayahuasca, a traditional Amazonian hallucinogenic drink made from Banisteriopsis caapi liana and other plants, faces multiple challenges despite advanced analytical techniques. Harmine and harmaline found in Andean archaeological sites have led some to suggest Banisteriopsis was used as early as 500 CE. However, archaeological, ethnobotanical, biochemical, and analytical chemistry considerations make the true origins of these alkaloids in mummies and artifacts uncertain. The evidence does not convincingly prove ancient ayahuasca use.
