>If the doors of perception were cleansed everything would
appear to man as it is, infinite.
>—William Blake
It was in 1886 that the German pharmacologist, Louis Lewin, published the
first systematic study of the cactus, to which his own name was subsequently
given. Anhalonium lewinii was new to science. To primitive religion and the
Indians of Mexico and the American Southwest it was a friend of
immemorially long standing. Indeed, it was much more than a friend. In the
words of one of the early Spanish visitors to the New World, "they eat a root
which they call peyote, and which they venerate as though it were a deity."
