What is Cordoncillo?

Cordoncillo (Piper aduncum) is a fast-growing medicinal shrub in the pepper family (Piperaceae), native to tropical regions of Central and South America and now naturalized across parts of Asia, Africa, and Oceania. It has been a cornerstone of traditional medicine in the Amazon basin, the Andes, and Mesoamerica for centuries, with healers using the leaves, bark, and essential oil to treat a wide range of conditions. The plant's distinctive spiked flower clusters give it its common name, which means 'little cord' in Spanish.

How does Cordoncillo work?

Cordoncillo's traditionally attributed benefits come primarily from its rich mix of essential oils, flavonoids, and tannins. Dillapiol and beta-caryophyllene are the main active compounds thought to be responsible for its antimicrobial and anti-inflammatory properties — dillapiol is believed to disrupt the cell membranes of bacteria and fungi, while beta-caryophyllene may interact with receptors involved in regulating inflammation and pain. Tannins are thought to create an astringent effect on wounds and mucous membranes that may help reduce bleeding, limit bacterial entry, and support tissue repair.

What forms does Cordoncillo come in?

The most traditional preparation is a warm leaf tea (infusion) used internally for digestion and respiratory issues, or applied externally as a wash on wounds and skin infections. Fresh or dried leaves can be made into a poultice and applied directly to cuts, ulcers, or inflamed skin. Tinctures and essential oil extracts are used in contemporary natural medicine practice. The essential oil is potent and should be diluted before any topical use.

Where it comes from:

Cordoncillo has been documented in use by dozens of Amazonian and Andean indigenous groups, including communities in Peru, Ecuador, Colombia, Panama, and Brazil. Spanish colonial-era botanical records from the 17th century documented the plant's use by local healers for wound care and digestive ailments. It gained the name 'Matico' in parts of South America, reportedly after a Spanish soldier named Matico allegedly discovered it by chance as a wound dressing. Today it remains a staple in folk pharmacies across Latin America and is studied by researchers interested in its antimicrobial and antiparasitic potential.

What does Cordoncillo help with?

• Wound healing and skin infections: Cordoncillo leaves have been traditionally used for generations as a wound dressing across tropical communities. The essential oil is traditionally regarded as having activity against certain bacteria and fungi, though clinical evidence in humans is lacking. The tannins are thought to create a protective film over the wound that may help slow minor bleeding and limit microbial entry while tissue repairs.
• Stomach pain and digestive upset: A warm tea made from the leaves is traditionally used for stomachaches, bloating, and indigestion across Latin America. The plant's tannins and compounds with potential anti-inflammatory properties are thought to help soothe irritated gut lining, and its traditionally attributed mild antimicrobial properties may play a role in digestive comfort, though this has not been confirmed in clinical trials.
• Fungal skin infections: Dillapiol and other compounds in the essential oil are thought to have activity against certain skin fungi including Candida species and dermatophytes. Topical washes or diluted oil preparations are traditionally used for ringworm, athlete's foot, and yeast-related skin irritation, though these uses have not been validated in clinical studies.
• Diarrhea and gut inflammation: Cordoncillo tea is a widely used traditional remedy for diarrhea and intestinal inflammation in tropical communities. The astringent tannins are thought to help firm loose stools and may offer a protective effect on irritated intestinal walls, while the plant's traditionally attributed antimicrobial properties are believed by practitioners to help address some underlying causes, though clinical confirmation is absent.
• Respiratory infections and cough: Inhaled steam from boiled Cordoncillo leaves and warm leaf tea are traditionally used for coughs, colds, and chest congestion. The essential oil is thought by traditional practitioners to have expectorant-like properties, and its compounds are thought to have some antimicrobial activity, though there is no clinical trial evidence supporting these uses in respiratory illness.
• Bleeding and wound hemostasis: One of Cordoncillo's most longstanding traditional uses is the application of pressed leaves to cuts and wounds to help slow bleeding. The high tannin content is thought to promote local astringent effects and may encourage protein coagulation at the wound surface, though this traditional practice has not been evaluated in controlled clinical studies.
• Parasitic infections (Leishmaniasis): Piper aduncum extracts are traditionally regarded as having activity against Leishmania parasites, with dillapiol and related compounds thought to affect the parasite's cellular structure. This remains one of the more investigated areas for the plant, but findings are preliminary and have not yet been confirmed through clinical trials in humans.
• Oral health and gum infections: Rinsing with diluted Cordoncillo tea or tincture is traditionally used to address gum inflammation, mouth ulcers, and minor oral infections. Practitioners have long attributed this benefit to the plant's antibacterial and astringent properties, which are thought to help reduce oral bacterial load and tighten inflamed gum tissue, though clinical evidence supporting these uses is currently lacking.
• Joint and muscle inflammation: Beta-caryophyllene, one of the compounds present in Cordoncillo, is thought to have potential anti-inflammatory properties. Topical application of leaves or diluted essential oil to sore joints and muscles is used in traditional practice with the aim of reducing local inflammation and pain, though this use remains observational and has not been confirmed in clinical trials.

What can Cordoncillo help prevent?

• Secondary wound infection (topical antimicrobial barrier may reduce infection risk in minor wounds)
• Recurrent fungal skin overgrowth (regular topical use may help suppress dermatophyte recolonization)

Which foods are rich in Cordoncillo?

Cordoncillo is a wild medicinal herb and is not found as a meaningful component of any food. To support its primary actions — antimicrobial defense, wound healing, and gut health — focus on foods rich in quercetin and kaempferol (onions, kale, apples, green tea), which share Cordoncillo's key flavonoids. Foods high in zinc (pumpkin seeds, legumes) and vitamin C (citrus, bell peppers) directly support wound healing and immune defense. Fermented foods like yogurt and kefir support the gut microbiome, reinforcing Cordoncillo's digestive benefits. Spices like cloves, black pepper, and oregano are naturally rich in beta-caryophyllene, the same anti-inflammatory compound found in Cordoncillo. Avoid highly processed, high-sugar foods, which promote fungal overgrowth and gut inflammation — working against Cordoncillo's core benefits.

What are the side effects of Cordoncillo?

• Skin irritation or contact dermatitis (undiluted essential oil, sensitive individuals)
• Nausea or stomach upset (high internal doses of concentrated extract)
• Potential liver stress with high-dose prolonged essential oil ingestion (safrole content)
• Allergic reaction in individuals sensitive to Piperaceae family plants
• Uterine stimulant effects reported in traditional use: avoid during pregnancy

Good to know:

Cordoncillo leaf tea and topical preparations are generally safe in traditional amounts and short-term use. The primary safety concern is the essential oil, which contains safrole — a compound regulated or banned as a food additive in many countries due to potential carcinogenicity at high doses. Avoid concentrated internal use of the essential oil, especially long-term. Safe for external use when diluted.

How much Cordoncillo should you take?

• Recommended daily: Leaf tea (infusion): 1–2 cups daily using 5–10 grams of dried leaves per cup. Tincture: 2–4 mL up to three times daily. Topical poultice or wash: apply as needed to affected area, 1–3 times daily. Essential oil (topical only): dilute to 1–2% in a carrier oil before application.
• Best time of day: Internal tea: with or after meals to minimize digestive irritation. Topical: apply morning and evening, or immediately after wound cleaning.
• With or without food: Take leaf tea with or after meals to reduce any risk of stomach irritation. Topical preparations are food-independent.
• Time to effect: Wound and skin conditions: noticeable improvement in 3–7 days. Digestive symptoms: relief often within 24–48 hours. Anti-inflammatory effects: 1–2 weeks of consistent use.
• How long to take it: For acute conditions (wound care, digestive upset, respiratory infection): use for 1–2 weeks as needed. For ongoing inflammatory or skin conditions: limit continuous internal use to 4–6 weeks, then take a 2-week break. Avoid long-term daily internal use of concentrated essential oil due to safrole content.
