I watched a documentary on cocaine production in Columbia. The green
leaf looks like it came off a tea tree. This is the form consumed by
the locals for altitude sickness. In the forest they build a large
pit and wet it with river water creating a mush pit. They throw in
the raw leaf and let it ferment for several weeks before they add
chemicals to extract the concentrated cocaine. The parallels to black
puer processing minus the chemicals was most interesting.

tail off here because I havent seen a description of the taste when
shu ages. Some say it doesnt loose the wodui taste but I beg to
differ.
