Chilcuague, also known as Aztec golden root, is a Mexican medicinal plant whose scientific name is Heliopsis longipes.
It belongs to the Asteraceae family and is traditionally used by indigenous peoples, particularly the Chichimeca, a group of indigenous tribes who inhabited northern and central Mexico before and during the arrival of the Spanish (16th century). They use the plant both as a natural remedy and as a condiment.
Chichimeca
These populations had well-defined cultures, adapted to more arid territories than Mesoamerican civilizations such as the Maya and Aztecs.
The name “Chichimeca” derives from the Nahuatl language of the Aztecs and was used to mean: “nomadic peoples”.
The used to live Northern Mexico (Guanajuato, Querétaro, Zacatecas, San Luis Potosí), semi-desert and mountainous areas (such as the Sierra Gorda).
They were perfectly adapted to a harsh environment, with water scarcity and extreme climate.
The Chichimeca had a strong knowledge of medicinal plants, natural remedies and nature-related rituals.
CHILCUAGUE
It grows wild in the montainous and semi-arid Sierra Gorda region (Guanajuato, Querétaro and surrounding areas), and the most valuable part is the root, rich in bioactive compounds.
It grows spontaneously in the wild, often in difficult terrain.
The name Chilcuague comes from Nahuatl language and means “root that tingles”, ot “viper pepper” (chile de víbora), due to the shape of its root, which resembles a snake. For the same reason, it is also known as chilmetal (chile de mecate), “rope pepper.”
This name perfectly describes its main effect: when the root is chewed, it causes strong salivation, tingling, and slight numbness in the mouth.
Botany of the plant
Chilcuague is a perennial herbaceous plant, rather simple in appearance, but with a very powerful root.
General structure
Height: approximately 50–70 cm
Stem: thin, green, slightly branched
Leaves: oval or lanceolate in shape, slightly serrated, edges, deep green color
Flowers: similar to small yellow daisies, composed of yellow petals and a darker center, typical of the Asteraceae family (like the sunflower)
The most important part: the root
This is where all the plant’s value is concentrated.
Color: Brown on the outside, light on the inside
Shape: Elongated and irregular, similar to a snake
Consistency: Fibrous
Flavor: Initially neutral
then spicy, pungent, and numbing
When chewed it causes an immediate tingling sensation. It stimulates saliva and it leaves a feeling of mild anesthesia.
Active Ingredients and Scientific Basis
The value of Chilcuague derives primarily from a class of molecules called alkamides, including:
- Affinin (spilanthol-like alkamide)
- Other phenolic compounds and flavonoids (in smaller quantities)
Phytochemical studies have shown that affinin has antimicrobial (against bacteria and fungi), anti-inflammatory, local analgesic properties.
Some research (including Mexican university studies, e.g., Querétaro 2018) shows an angiogenic effect (it promotes the formation of new blood vessels), and a vasodilatory activity.
The “fizzing/anesthetic” effect in the mouth is due to the stimulation of sensory receptors (similar, but more intense, than pepper or ginger).
With sweet and mellow notes, Chilcuague opens the taste buds, producing a unique sensation on the tongue and palate that’s difficult to explain.
It’s also used for these properties as a seasoning in foods. It’s used as a condiment in salsas, beans, nopal, and other Mexican regional dishes. Its root is also used to infuse a white agave distillate.
Chilcuague offers a sensory experience that broadens the horizons of gastronomy by enhancing the flavors of foods and beverages, completely changing the way the taste buds detect these flavors. They “open,” amplifying their ability to perceive flavors.
For its connoisseurs, there’s a before and after of eating chilcuague in their gastronomic experiences.
Its colloquial name, chilcuague, comes from Nahuatl and means “viper pepper” (chile de víbora), due to the shape of its root, which resembles a snake. For the same reason, it is also known as chilmetal (chile de mecate), “rope pepper.”
Main physiological effects and benefits
IMPROVED DIGESTION
Salivary stimulation (sialogogue effect)
When chewed it rapidly increases saliva production and so it activates digestive enzymes such as amylase
and lipase and promoting the secretion of endorphins.
This leads to:
- Improved digestion
- Regulation of oral and gastric pH
- Reduction of acidity and reflux
IMPROVED IMMUNE SYSTEM
Alkamides can modulate the immune response and have a good immunostimulant effect
NATURAL ANTIBIOTIC
Antibacterial activity demonstrated in the laboratory. It is very useful for: oral infections, digestive/respiratory infections, sore throat and oral infections.
Combined action:
Antiseptic
Anesthetic
Reduces pain and irritation
ANTIFUNGAL
Active against fungi such as those responsible for Athlete’s foot (skin mycoses)
Traditionally used topically
ANTIVIRAL
Promotes:
Microcirculation
Tissue regeneration
Useful for small wounds or irritations
ANTI-INFLAMMATORY
Reduces local inflammation (muscles, gums, skin); this effect is linked to the action of alkamides.
NATURAL ANESTHETIC
Rapid effect in the mouth:
numbness and tingling
Useful for toothache and gum irritation.
VASODILATOR
Promotes blood flow and contributes to a better tissue oxygenation. It is perceived as a “heat” effect.
ANTITUMOR
Some preliminary studies indicate activity on tumor cells (e.g., skin)
DIGESTION AND ACIDIC REFLUX
Stimulates digestive enzymes and helps with
slow digestion, stomach acidity, bloating
HOW TO USE IT
It has no expiration date and should be stored in a dry, closed place.
Spray once a day in the mouth.
It’s a natural antibiotic and it works on the healing of throat chakra.
