About Coca leaf
Botanical and ecological description

Coca plant is a bush that
can reach heights of 1.5 up to 3 meters; it has specific and constant
botanical characteristics. The coca bush lives for many years. It grows
in South America: in all the Peruvian, Bolivian, Ecuadorian, Brazilian,
Chilean and Colombian territory.
The leaves have very clear
longitudinal curved lines curved towards the central vein that are
simply thickened from the epidermis cells resulting from the way the
leaf rolls. In the base of the petiole it has oval stipulates made
intrapecioral characteristics. The flowers are creamy white almost
reaching 1cm and it has five sepals and five petals. When the fruit is
ripe, two of the ovules abort, and the loculos are destroyed. The fruit
is drupe red, oval with a single seed.
The plant is cultivated in
the mountain prairies or plateau terraces, in a tropical and subtropical
climate. It can grow in atmospheres unfavorable for other plants.
Optimal conditions for the growth of coca bushes are related to humus
and clay grounds, rich in iron, and located in valleys surrounded by
mountains, where there is a high humidity level and it frequently rains.
The plant normally lives up to 30 or 40 years and in ideal conditions it
can live up to 100 years.
Plants of this type are
cultivated in mountain slopes or plateau terraces that have a tropical
or semitropical climate. The plant grows under conditions not suitable
for other types of planting. The best conditions for the development of
the coca plant are earth with layer of clay, rich in humus and iron,
located in protected plateau valleys, where there is permanent humidity
and it frequently rain. The plant normally lives and produces for 30 to
40 years; under ideal conditions, it could survive up to 100 years.
Harvesting and Advantages
The harvesting of the leaves
is made 3 to 4 times per year. The coca leaf contains an average of 0,5
to 1,5% of alkaloids, although there are several factors that influence
the pick up, like atmospheric conditions, the age and condition of the
plant, the quality of the earth, the installments used, the time of
planting, the harvest, etc.
The drying process is very
important and it takes approximately 2 to 3 days out in the sun. During
this process, the leaves must be turned for an even drying. In the
drying process the leaf loses more than 75% of its original weight. Once
the leaves are dry, they are pressed and packed by arrobas (11,5 kg) for
its commercialization.
Use
The use of coca leaves is a
millenarian tradition throughout the Andean Region. The coca is a
mythical and sacred plant; it was used in rituals more than 40 centuries
ago. Nowadays it continues to be an indispensable component when
sacred-cults are taken place.

digestive system, prevent the altitude syndrome (vertigo, vomit),
prevents physical exhaustion, cramps, toothaches, rheumatic pains, when
