yes it is one of the ones. along with others. teh difference with peyote is it has other alkaloids in it as well as mescaline making it a little different than other cacti. its interesting to note that apparently indians from as far as canada journeyed to souther US to collect this cacti (perhaps others). Other tribes ( i forge the names...) were known to run for days staright with the use of this plant. it definatly has soem history. from a botany point of veiw and an exploration point of veiw the book "One River" is a pretty fun read about teh more narcotic ethnogens and the work of Shultz.
i am suprised that bamboo has not been mentioned. if i were to guess, i would say it has to be among the top 10 ethnogens in human civilization.
interesting. is "white mulberry" the same sp that are used, or were rather, to feed silkworms? the mulberry family is one interesting group of plants! so many uses.
Here's another plant that I love:
It's called "clitoria macrophylla".
I like it because of it's name, and its "appropriate" shape.
Also, it's roots produce the drug clitoriacetal.
