Erythroxylon coca
Erythroxylon coca is a densely-leafed plant native to the eastern slopes
of the Andes.
It is a small shrubby tree ranging from 12 to 18 feet high in the wild state and kept down to about 6
feet when cultivated. It is grown from seeds and requires moisture and an equable
temperature. Usually a plant will start yielding alkaloids such as cocaine in seventeen months and often
remains productive for over fifty
years. The leaves are gathered three times a year: in March-April, in June, and
in October.

The leaves are rich in vitamins, protein, calcium, iron and
fibre. There are many alkaloids in Coca leaves (Cocaine, Annamyl Cocaine,
Truxilline or Cocamine etc.). The cocaine content of the leaves ranges from O.1%
to 0.9%; like the user, it tends to get higher with altitude! Coca leaves deteriorate very quickly in a damp atmosphere, and for this reason the alkaloid is extracted from the leaves in South America before exportation.
