What is Chilcuague?

Chilcuague, known scientifically as Heliopsis longipes, is a perennial plant native to the highland regions of Mexico — particularly the states of San Luis Potosí, Hidalgo, and Querétaro. It belongs to the Asteraceae family, the same family as sunflowers and daisies, and produces cheerful yellow flowers through the summer months.

The real magic lives underground, in the roots.

When chewed or applied as a spray, the root produces an unmistakable tingling, numbing, and electric sensation in the mouth and tongue. This is the signature of its primary active compound: affinin (also known as spilanthol), a powerful alkamide that acts directly on sensory receptors in the nervous system.

Traditional Uses

Chilcuague was considered powerful medicine long before the Spanish arrived in Mexico. It held an important place in pre-Hispanic healing traditions and has been used continuously in Mexican folk medicine ever since.

• Oral & Dental Health

  Traditionally chewed to numb the gums and relieve tooth discomfort. Long used in teething remedies for infants.
• Throat & Respiratory Support

  Traditionally used for throat infections, pharyngitis, tonsillitis, laryngitis, and esophagitis. Applied directly to the throat for localised relief.
• Skin & Wound Care

  Traditionally applied topically for minor wounds, burns, skin infections, fungal conditions, insect bites, and skin irritations.
• Digestive Support

  Traditionally used to ease stomach discomfort, stimulate digestion, and support the body in addressing intestinal parasites.
• Antimicrobial & Antifungal

  Traditionally used against fungal conditions including athlete's foot, candida, dandruff, and onychomycosis. Also applied for gingivitis and oral infections.
• Pain & Inflammation

  Traditionally used for muscle pain, rheumatism, neuralgia, and general aches. The root's analgesic properties have been documented in scientific literature.
• Culinary Tradition

  Beyond medicine, Chilcuague root is traditionally used as a culinary spice — a fiery, numbing substitute for black pepper — and as a flavouring in alcoholic beverages.

The Active Compound: Affinin

The distinctive tingling sensation of Chilcuague is down to a single key molecule:

Affinin is also found in the related plant Spilanthes acmella — the “toothache plant” or Jambu — which produces a similar effect. During World War II, the insecticidal potency of affinin was found to be comparable to pyrethrin, a discovery that unfortunately triggered heavy commercial over-harvesting of wild Chilcuague, significantly reducing its natural population. Responsible cultivation is now increasingly important for preserving this plant.

Why a Spray?

The spray format makes this traditional root easy to use and reliably dosed. Rather than chewing raw root — which produces an intense and prolonged numbing experience — the spray delivers the extract directly where you need it: to the mouth, throat, or tongue.

It's popular at festivals, events, and in daily wellness routines. Once experienced, people tend to come back for it again and again. Pick up a bottle from our Chilcuague Spray product page.

Chilcuague vs. Spilanthes

Both plants contain affinin/spilanthol and produce a similar tingling, electrifying sensation. Here's how they differ:
