There are various species of psychedelic cacti; the common active constituent
is Mescaline, though other alkaloids are reported to be present in differing
species.
My personal experience with cacti is limited. I have not ingested, but I
did get some seeds from 'Gnostic
Garden'>>. I bought some Peyote and some 'Peruvian Torch'. They
took months to germinate. I almost gave up on them. Out of about 20
planted Peyote seeds I got one cactus. Out of about 60 planted 'Peruvian
Torch' seeds I got four cacti.
It should be noted that my germination procedures were a bit rough and
ready, consisting basically of sticking the seeds in a pot and trusting to luck.
I did use cactus compost, and for some of them I did microwave the soil to
sterilise it before planting the seeds. I could see that the sterilised
pots definitely had less subsequent growth of moss on the soil surface.
There are doubtless more steps that could be taken that would probably ensure a better
success rate. A good web-site is Ethnobotany
Lophophora>>
My seeds germinated at the end of summer 2000. The peyote did not survive
the first winter (even though all cacti were sown and grown indoors). The
Peruvian Torch did survive, though
growing hardly at all. - Tiny things, the size of my little fingernail!
Subsequent summers have seen an acceleration in growth rates, the biggest
reaching10-15cm in height by the end of the second year.
There follows some brief notes on some of the species:
Peyote (Lophophora williamsii) aka: Peyolt
The most frequently heard of species, which has become known through its
traditional use by native Mexican/American cultures. Peyote was one of the
principle psychoactive plants given to Carlos
Castaneda, referred to particularly in his earlier books in his accounts of
teachings of don Juan. More recently (and after some 'to-ing and fro-ing') it
has been granted some legal recognition in the US with regard to its use by
practitioners of the 'Native American Church'.
Due to increasing demands Peyote is becoming rarer in the wild. It can be
cultivated, but it grows quite slowly, and after investigating alternatives many
people grow other species of psychedelic cacti.
San Pedro (Trichocereus pachanoi) aka: Aguacolla, Achuma, Huachuma,
Gigantón
This faster growing columnar cactus is a popular alternative to Peyote. It has
been traditionally employed by shamans in the diagnosis and curing of illness
since around 1300 BC in the Andes of Peru, Ecuador and Bolivia.
Peruvian Torch (Trichocereus peruvianus)
Similar to San Pedro (T. pachanoi) but with longer brown spines, this
species is often preferred San Pedro as being more potent and even faster
growing. It can reach a height of well over 2 meters can withstand temperatures
as low as -4°c.
