## Overview

Cordoncillo negro (Piper aduncum) is an Amazonian plant containing dillapiol, linalool, and nerolidol compounds that demonstrate antifungal and [antimicrobial](/ingredients/condition/immune-support) properties. Laboratory studies show activity against skin pathogens and various bacterial strains, though clinical evidence remains limited.

## Health Benefits

• Antifungal activity against skin and nail infections (in vitro evidence only, attributed to dillapiol, linalool, and nerolidol compounds)
• [Antimicrobial](/ingredients/condition/immune-support) effects against various bacteria strains (preliminary laboratory studies only)
• Traditional use for digestive issues including stomachache, ulcers, and diarrhea (no clinical trials available)
• Historical application for respiratory conditions like bronchitis and coughs (traditional use only, no clinical validation)
• Wound healing and hemostatic properties (based solely on traditional use dating to Spanish colonial period)

## Mechanism of Action

Cordoncillo negro's bioactive compounds, particularly dillapiol, linalool, and nerolidol, disrupt fungal cell membrane integrity and bacterial cell wall synthesis. These essential oil components interfere with ergosterol biosynthesis in fungi and peptidoglycan formation in bacteria. The [antimicrobial](/ingredients/condition/immune-support) activity appears to involve multiple cellular targets, making resistance development less likely.

## Clinical Summary

Current evidence for cordoncillo negro consists primarily of in vitro laboratory studies demonstrating antifungal activity against dermatophyte species and [antimicrobial](/ingredients/condition/immune-support) effects against gram-positive and gram-negative bacteria. No randomized controlled trials in humans have been published to date. Traditional use documentation exists for digestive complaints and topical applications, but lacks quantified clinical outcomes. The strength of evidence remains preliminary and requires human clinical validation.

## Nutritional Profile

Piper aduncum is not consumed as a food staple and therefore lacks a conventional macronutrient profile (calories, protein, fat, carbohydrates, fiber are not meaningfully characterized in dietary terms). Its relevance is almost entirely phytochemical/bioactive. Key bioactive compounds identified in essential oil and leaf extracts include: • **Dillapiol** (phenylpropanoid) — dominant constituent of the essential oil, often comprising 40–90% of total oil depending on chemotype and geographic origin; reported concentrations in Amazonian specimens frequently range from 60–85% of essential oil content. Exhibits antifungal and synergistic insecticidal activity. • **1,8-Cineole (eucalyptol)** — typically 2–10% of essential oil; contributes to [antimicrobial](/ingredients/condition/immune-support) and mild bronchodilatory properties. • **Piperitone** — variable, reported at 1–8% in some chemotypes. • **Linalool** (monoterpene alcohol) — typically 0.5–5% of essential oil; mild antimicrobial and anxiolytic properties. • **trans-Nerolidol** (sesquiterpene alcohol) — reported at 1–7%; antifungal and antiparasitic activity noted in vitro. • **β-Caryophyllene** (sesquiterpene) — approximately 1–6% of essential oil; [anti-inflammatory](/ingredients/condition/inflammation) via CB2 receptor agonism. • **Myristicin** — trace to minor amounts (~0.5–3%); structurally related to dillapiol. • **Flavonoids** — including 2',6'-dihydroxy-4'-methoxychalcone and other chalcones isolated from leaves; concentrations not precisely quantified in bulk tissue but detected in methanol/ethanol extracts. These exhibit [antioxidant](/ingredients/condition/antioxidant) and anti-inflammatory activity. • **Chromenes** (e.g., methyl-2,2-dimethyl-2H-chromene-6-carboxylate)** — minor constituents with reported bioactivity. • **Tannins and phenolic acids** — present in aqueous and ethanolic leaf extracts; total phenolic content reported at approximately 30–80 mg gallic acid equivalents (GAE) per gram of dry extract, depending on extraction method. • **Saponins** — detected qualitatively in leaf extracts. **Mineral content** of dried leaves (limited data): potassium, calcium, magnesium, and iron are present in trace amounts consistent with tropical herbaceous plants, but precise quantification specific to P. aduncum is sparse in the literature. **Vitamins**: No reliable data on vitamin content. **Bioavailability notes**: Dillapiol and other phenylpropanoids are lipophilic and moderately absorbed through gastrointestinal mucosa when consumed as teas or decoctions, though first-pass hepatic [metabolism](/ingredients/condition/weight-management) is significant. Essential oil constituents are volatile and partially lost during traditional boiling preparations. Flavonoid bioavailability is generally low (estimated <5–10% oral absorption) without lipid co-administration. Topical application of essential oil allows direct dermal absorption of dillapiol and terpenes, which is the more relevant route for antifungal use. Dillapiol is also a known inhibitor of cytochrome P450 enzymes, which may alter metabolism of co-administered substances.

## Dosage & Preparation

Traditional herbal literature recommends infusions of 1g herb per cup, 2-3 times daily, or 10% infusion 3-4 times daily. No clinically studied dosages are available due to lack of human trials. Consult a healthcare provider before starting any new supplement.

## Safety & Drug Interactions

Safety data for cordoncillo negro supplementation is limited, with no established safe dosage ranges or comprehensive toxicity studies. Essential oil components like dillapiol may cause skin sensitization or allergic reactions in susceptible individuals. Potential interactions with antifungal medications or antibiotics are unknown due to lack of pharmacokinetic studies. Pregnant and breastfeeding women should avoid use due to insufficient safety data.

## Scientific Research

No human clinical trials, RCTs, or meta-analyses have been conducted on Cordoncillo Negro. Evidence is limited to in vitro studies demonstrating [antimicrobial](/ingredients/condition/immune-support), antifungal, and cytotoxic effects on cancer cells and bacteria in laboratory settings.

## Historical & Cultural Context

Used for centuries in Latin American traditional medicine, Cordoncillo Negro was reportedly discovered by a Spanish soldier nicknamed 'Matico' who used it for wound hemostasis. In Peruvian traditional medicine, it treats digestive, urinary, and respiratory conditions, as well as bleeding disorders and infections.
