Peyote (Lophophora williamsii) is the sacred cactus of the Native American Church. The green parts are harvested for their mescaline, a potent entheogen. These specimens are for growing indoors.
The active alkaloids of the Peyote cactus are:
mescaline (3,4,5- trimethoxy-B-phenethylamine)
The most important active alkaloid is mescaline.
These cacti should be grown for a couple of years before their green buttons can be harvested (which can be done without killing the cactus itself).
