Yopo seeds are used to prepare a visionary snuff used by various tribes in South America for over 4000 years for its spiritual and healing purpose. The scientific name of the plant is 'Anadenanthera Peregrina' that makes a clear reference to the Sanskrit word ‘ananda’ meaning bliss. Yopo is considered a cousin of the sacred Caapi vine which is used to prepare the Ayahuasca brew. It contains DMT and is sometimes also ingested along with Caapi vine to potentiate the effects.
