Auyahuasca also known as Yage' is a drink made from a number of plants in the South American jungle. Usually it requires at least two different plants, one containing dimethyltryptimine (DMT) and the other containing an MAOI.
The Yage vine, Mimosa Hostillis Root Bark, various grasses all contain DMT, quite possibly the strongest hallucinatory drug known to man (with the exception of Salvia Divinorium, which is really difficult to use properly). However, the body quickly builds up a tolerance to DMT. so drinking a tea with DMT in it is useless. That is, unless you have another plant in the tea that contains an MAOI (MAO Inhibitor). When these to drugs are combined and consumed, you enter a world of different realities.
Most people who drink this particular concoction, find themselves watching a movie between them and reality. They see reality all areound them, but superimposed over that is another reality.
Today, many people take DMT in another fashion. They will extract it by freebase chemisty from the plant matter. This creates a yellowish crystal which can be smoked. After about three hits, the voyager no longer sees reality at all and usually find themselves folowing the same sort of trip that others have. Many times they see gnomes/faries/elves. In fact crytsalized DMT is sometimes called Elfspice.
The song written by Sid Barrett about the Little Gnome, is often thought to have been inspired by a DMT trip after all, as he sings... "The Gnomes Have Found A New Way To Say Hooray". This trip usually lasts 20 minutes or less and as Leary put it,
"It lasted for a million years and for a split-second. But it's over and now it's your turn."
Good stuff, of course highly illegal and I would never do anything illegal.
