San Pedro / Peruvian Torch Cactus

San Pedro cactus is the name given to psychoactive species of the genus Trichocereus .As with the well known peyote cactus it contains mescaline as well as other psychoactive aklaloids.
Like many other of the entheogenic substances used in the aboriginal religions of the Americas, the use of the hallucinogenic San Pedro cactus is ancient and its use has been a continuous tradition in Peru for over 3,000 years.
An account of the cactus by a shaman:
‘the drug first ... produces ... drowsiness or a dreamy state and a feeling of lethargy ... a slight dizziness ... then a great 'vision', a clearing of all the faculties ... it produces a light numbness in the body and afterward a tranquillity. And then comes detachment, a type of visual force ... inclusive of all the senses ... including the sixth sense, the telepathic sense of transmitting oneself across time and matter ... like a kind of removal of one's thought to a distant dimension’.

Traditional preparations include boiling into a tea and chewing. 20gms for 2-4 people in a tea is a good dose.
Effects may last 4-12 hours.
