Botanical Overview
Coca (Erythroxylum coca var. coca) is a flowering plant in the Erythroxylaceae family. Traditional medicine systems have documented several valuable applications for this species, supported by its observed therapeutic effects. The coca family (Erythroxylaceae) includes tropical shrubs and small trees with alternate leaves and small flowers. The plants produce alkaloids concentrated in the leaves, most notably cocaine and related tropane alkaloids. Species in this family have a long history of traditional stimulant and medicinal use in South America.
Family Context
The Erythroxylaceae family is primarily neotropical. Notable medicinal members include:
- Amazonian Coca — 42 documented uses
- Guarda orvalho — 1 documented uses
- Arabillo — 1 documented uses
Geographic Distribution
Coca has been recorded in 7 countries and territories worldwide, including Bolivia, Colombia, Costa Rica, Ecuador, Peru, and others.
Traditional Uses
Coca has been traditionally used for digestive health, respiratory conditions, and urinary tract health, among other applications.
Digestive health.
- Carminative
For digestive complaints, the herb is typically prepared as a tea or decoction taken before meals. The bitter compounds stimulate digestive secretions and improve nutrient absorption. Some traditions use the powdered root or leaves in small doses as a stomachic tonic.
Respiratory conditions.
- Asthma
Respiratory conditions are addressed through steam inhalation of the herb’s vapors or internal use as a warm tea. The hot infusion acts as an expectorant, helping to loosen phlegm and clear congestion. Some traditions combine it with honey for coughs.
Urinary tract health.
- Diuretic
- Edema
Urinary tract applications typically involve drinking the herb as a mild tea, which increases urine production and helps flush the urinary system. It may be combined with other demulcent herbs to soothe irritated tissues.
