What are the horticulural aspects of Erythroxylum coca?

Erythroxylum coca grow in tropical regions with high altitudes, typically between 2,000 to 4,000 meters above sea level, with mild temperatures between 15°C to 25°C and high humidity.

Plants should be planted in well-draining acidic soil with a pH between 5.5 and 6.5, in a location with partial shade, and spaced 1 to 2 meters apart, with the nursery seedling being transplanted after 6 to 8 weeks.

Harvesting occurs when the leaves reach an optimal size and maturity, usually between 3 to 12 months after planting, with the top leaves being harvested more frequently than lower leaves, and the plant regenerating from axillary buds.

Common pests and diseases affecting Erythroxylum coca include the coca beetle, the coca moth, and fungal diseases such as leaf spot, powdery mildew, and root rot, which can be controlled with integrated pest management and proper crop rotation practices.

What are the botanical aspects of Erythroxylum coca?

Erythroxylum coca is an evergreen shrub or small tree that grows up to 3 meters in height, with elliptical leaves that are 5-12 cm long and 2-5 cm wide. The leaves are dark green on top and pale green on the bottom.

Erythroxylum coca belongs to the family Erythroxylaceae and is classified as a member of the order Malpighiales. The species has a single accepted name, but it is sometimes referred to as E. coca or E. andinum.

There are several variants of Erythroxylum coca, including E. coca var. coca and E. coca var. iperou. These variants differ in leaf size and shape, as well as in their geographical distribution.

Erythroxylum coca is native to the tropical regions of South America, including Colombia, Peru, Bolivia, and Ecuador. It is also cultivated in other parts of the continent and in Southeast Asia.

The life cycle of Erythroxylum coca involves a period of dormancy during the dry season, followed by a rapid growth phase during the wet season. The plant produces flowers and fruit year-round, with the fruit being a small, red or yellow drupe.

What are the historical aspects of Erythroxylum coca?

Erythroxylum coca is an evergreen shrub native to South America, whose leaves have been used for centuries in traditional medicine and as a stimulant. In pre-Columbian civilizations, coca leaves were chewed for energy, endurance, and spiritual purposes. They were also used as currency.

In Inca mythology, coca leaves were associated with the goddess Pachamama, the earth mother, and were believed to have healing properties. The myth of the sun and the moon, where the sun was born from the coca leaf, is also well-documented. Coca was also associated with fertility.

In many cultures, coca leaves have symbolic meanings, representing abundance, fertility, and spiritual growth. They are also associated with the Andean concept of "q'ente," or harmony with nature. The leaves are often used in rituals to connect with the natural world.

Historical texts, such as the Spanish chronicles of the conquistadors, document the use of coca leaves in pre-Columbian societies. The Spanish friar Bartolomé de Las Casas wrote extensively about the importance of coca in Inca culture. The German naturalist Alexander von Humboldt also documented its use in South America.

Archaeological artifacts, such as ceramic vessels and textiles, depict scenes of coca leaf harvesting and ritual use. The Museo Nacional de Antropología in Mexico City has a collection of artifacts related to coca use, including ceremonial masks and ritual objects. The National Museum of Archaeology in Lima, Peru, also has a significant collection of coca-related artifacts.
