## Overview

Erythroxylum coca is an Amazonian plant containing cocaine alkaloids and polyphenols traditionally used by Andean peoples for energy and altitude adaptation. The primary bioactive compounds work through [dopamine](/ingredients/condition/mood) and norepinephrine reuptake inhibition, though clinical evidence is limited to traditional use patterns.

## Health Benefits

• Traditional stimulant properties - used by Andean peoples for energy and altitude sickness relief (traditional use only, no clinical trials)
• High dietary fiber content (>50% in leaves) - may support [digestive health](/ingredients/condition/gut-health) (compositional analysis only)
• Contains polyphenols (1.2-1.5 mg eq AG/g) - potential [antioxidant](/ingredients/condition/antioxidant) properties (preliminary evidence)
• Rich in organic acids including succinic acid (11,666 mg/g) - possible metabolic support (compositional data only)
• Traditional use for pleasant stimulation and tea-like effects (historical use only, no RCTs)

## Mechanism of Action

The primary alkaloids in Erythroxylum coca, including cocaine (0.5-1% in leaves), function as monoamine reuptake inhibitors, blocking dopamine, norepinephrine, and [serotonin](/ingredients/condition/mood) transporters. Secondary compounds like polyphenols (1.2-1.5 mg eq AG/g) may provide antioxidant activity through [free radical scaveng](/ingredients/condition/antioxidant)ing mechanisms. The high fiber content (>50%) supports digestive function through mechanical and [prebiotic](/ingredients/condition/gut-health) pathways.

## Clinical Summary

No controlled clinical trials exist for Erythroxylum coca as a supplement ingredient. Evidence is limited to ethnobotanical studies documenting traditional use patterns among Andean populations for energy and altitude sickness management. Compositional analyses confirm alkaloid content and fiber levels, but therapeutic efficacy remains unestablished. Legal restrictions severely limit research opportunities for clinical investigation.

## Nutritional Profile

Erythroxylum coca leaves present a distinctive nutritional composition documented primarily through phytochemical and compositional analyses. Dietary fiber is the dominant macronutrient component, exceeding 50% dry weight of the leaf material, with structural polysaccharides comprising the bulk of this fraction. Protein content in dried coca leaves has been reported at approximately 19-20% dry weight in select analyses, notably higher than many conventional leafy botanicals, though bioavailability via traditional chewing/infusion methods is substantially reduced compared to direct consumption. Fat content is low, estimated at 3-5% dry weight. The primary bioactive alkaloid fraction totals approximately 0.5-1.0% dry weight in cultivated leaves, dominated by cocaine alkaloids alongside cinnamoylcocaine derivatives (truxillines), tropacocaine, and hygrine; these compounds are responsible for the traditional stimulant and anesthetic effects and are not nutritionally relevant in a conventional dietary sense. Polyphenol content has been quantified at 1.2-1.5 mg gallic acid equivalents per gram, encompassing flavonoids and hydroxycinnamic acid derivatives with preliminary [antioxidant activity](/ingredients/condition/antioxidant). Organic acid profile includes succinic acid, malic acid, and citric acid as primary identified constituents. Mineral content documented in Andean ethnobotanical analyses includes calcium (approximately 997 mg/100g dry weight), iron (approximately 26 mg/100g dry weight), and phosphorus, with bioavailability enhanced by the alkaline ash (llipta or cal) traditionally co-administered during chewing, which raises oral pH and facilitates alkaloid and mineral release. Vitamins A, B2 (riboflavin), and C have been reported in compositional studies of dried leaf, with vitamin C estimates ranging 2-10 mg/100g depending on processing. Bioavailability of most constituents via infusion (mate de coca) is considerably lower than chewing with alkaline adjuncts, and dried/processed leaf forms show further degradation of thermolabile compounds.

## Dosage & Preparation

No clinically studied dosage ranges have been established for Erythroxylum coca extracts, powders, or standardized forms. Traditional use involves chewing dried leaves, but no quantified doses from clinical studies are available. Consult a healthcare provider before starting any new supplement.

## Safety & Drug Interactions

Erythroxylum coca contains controlled substances (cocaine alkaloids) that are illegal in most jurisdictions. Even traditional preparations may cause [cardiovascular](/ingredients/condition/heart-health) stimulation, anxiety, and dependence potential. The plant may interact with MAO inhibitors, stimulant medications, and cardiovascular drugs through its alkaloid content. Pregnancy and lactation use is contraindicated due to alkaloid transfer risks and lack of safety data.

## Scientific Research

No human clinical trials, RCTs, or meta-analyses were identified for Erythroxylum coca leaves or extracts. One compositional study (PMID: 9201607) analyzed Bolivian E. coca leaves but reported no clinical outcomes. Research focuses primarily on chemical composition rather than clinical efficacy.

## Historical & Cultural Context

Erythroxylum coca leaves have been chewed for centuries by Aymara and Quechua peoples in Bolivia and Peru as a general stimulant, with preference for sweeter Yungas varieties. Use dates back millennia in South American indigenous cultures for energy and altitude sickness relief.

## Frequently Asked Questions

### What alkaloids are found in Erythroxylum coca leaves

Erythroxylum coca leaves contain 0.5-1% cocaine along with related tropane alkaloids including ecgonine and benzoylecgonine. These compounds are responsible for the plant's stimulant properties but are classified as controlled substances in most countries.

### Is Erythroxylum coca legal as a supplement ingredient

Erythroxylum coca is illegal as a supplement ingredient in the United States and most countries due to its cocaine alkaloid content. The plant is classified as a controlled substance under international drug conventions despite traditional use patterns.

### How much fiber is in Erythroxylum coca leaves

Erythroxylum coca leaves contain over 50% dietary fiber by dry weight according to compositional analyses. This high fiber content may contribute to digestive benefits observed in traditional use, though clinical studies are lacking.

### What polyphenols are present in Erythroxylum coca

Erythroxylum coca contains 1.2-1.5 mg gallic acid equivalents per gram of polyphenols, including flavonoids and phenolic acids. These compounds may contribute antioxidant properties, though their bioavailability and clinical significance remain unstudied.

### Can Erythroxylum coca help with altitude sickness

Traditional use among Andean peoples suggests Erythroxylum coca may help with altitude adaptation, likely through stimulant alkaloid effects on respiratory and cardiovascular function. However, no controlled studies have validated this use, and legal alkaloid-containing preparations are unavailable.

### What are the safety concerns with Erythroxylum coca supplementation?

Erythroxylum coca contains cocaine alkaloids, which carry significant cardiovascular and neurological risks including elevated heart rate, blood pressure, and potential for dependence. Due to the presence of controlled alkaloids, regulatory status varies by country and many jurisdictions restrict its sale as a dietary supplement. Individuals with hypertension, heart conditions, or psychiatric disorders should avoid this ingredient entirely. Clinical safety data in humans is unavailable, making risk assessment based primarily on traditional use and chemical composition rather than controlled trials.

### Who should avoid Erythroxylum coca and are there specific contraindications?

Pregnant and breastfeeding women should avoid Erythroxylum coca due to the potential for alkaloid transfer and unknown developmental effects. Individuals taking stimulant medications, cardiovascular drugs, or psychiatric medications should not use this ingredient without medical supervision, as alkaloid interactions are poorly characterized. People with a personal or family history of substance use disorder, anxiety disorders, or cardiac arrhythmias are at higher risk for adverse effects. The ingredient is unsuitable for children and generally not recommended for elderly individuals with comorbid conditions.

### How does the form of Erythroxylum coca affect its composition and safety profile?

Whole leaf preparations, leaf extracts, and alkaloid-isolated forms of Erythroxylum coca contain significantly different concentrations of cocaine and other alkaloids, making dose control and safety unpredictable across products. Alkaloid concentration varies with plant origin, harvest time, and processing method, creating inconsistent supplement formulations. Water-based traditional preparations (such as coca tea) typically contain lower alkaloid levels than concentrated extracts, though exact content remains poorly standardized. The lack of standardization means consumers cannot reliably determine actual alkaloid exposure from product labels alone.
