Coca

Erythroxylum coca

Also calledKuka (Quechua) · Mama Coca (Andean) · Hayu / Ipadú (Amazonian, for Amazonian coca) · Coca (Spanish) · 古柯 gǔkē (Chinese)

The sacred leaf of the Andes, chewed for thousands of years to ease hunger, fatigue and altitude. Its leaves contain about 0.5–1% cocaine, which in the leaf form is mild, but became a powerful drug of addiction once it was extracted in 1860.

Erythroxylum coca is a species of flowering plant in the family Erythroxylaceae. It is one of the two species of cultivated coca. Wikipedia

§1

What it can do

  1. iMakes cocaine and related alkaloids in its leaves, which deter insect herbivores
  2. iiGrows on steep, terraced Andean slopes and can be harvested several times a year
  3. iiiIts leaf is nutritious, with significant calcium and iron

Eatenleaves (chewed or brewed as tea)

Leaves are chewed with an alkaline ash (llipta) or brewed as mate de coca, legal in Peru and Bolivia but illegal in many countries. Extracted cocaine is highly addictive and can cause heart attack, stroke and death. Leaf use causes positive drug tests.

§3

In the medicine cabinet

TraditionUse
Andean traditional medicineLeaves chewed or drunk as tea for altitude sickness, hunger, fatigue and stomach pain
Modern medicineCocaine hydrochloride used as a topical anaesthetic and vasoconstrictor in nose and throat procedures

Weight of evidence

Strong. An approved drug, or consistent results in well-run clinical trials.

Active compounds

cocaine, cinnamoylcocaine, hygrine, tropacocaine

CautionCocaine is addictive and cardiotoxic. Leaf products are controlled in most countries outside the Andes.

In the old herbals & bestiaries

No plate in the Source Library names this exact species, so these show its closest relatives as the old naturalists drew them: same genus, or the same kind of plant. Click a plate to read the page it came from, with translation.

§8

Marginalia

Coca appears in Moche ceramics showing chewers with bulging cheeks, and under the Inca its use was reserved largely for nobility and ritual. Albert Niemann isolated cocaine in 1860, and in 1884 Carl Koller showed it could numb the eye for surgery, the first local anaesthetic.

Curiosity

Coca-Cola originally contained coca extract; the company still uses de-cocainised coca leaf flavouring, processed by a single licensed US facility.
