The root that tingles — and why it hasn’t been forgotten for centuries.
Anyone who places a few drops of Chilcuague extract on the tongue for the first time experiences something unexpected: an intense tingling that spreads across the lining of the mouth, a slight numbness, followed by a clear, invigorating sensation. No spice, no plant tincture behaves quite like it. That is exactly what makes Chilcuague one of Mexico’s most fascinating botanical treasures — and the most requested product in the YOMERA shop.
The plant: Heliopsis longipes
Botany and appearance
Heliopsis longipes belongs to the daisy family (Asteraceae) — distantly related to chamomile, marigold, and coneflower. A perennial plant with bright yellow flower heads that resemble small sunflowers. Hence the nickname: Golden Root.
The real treasure lies underground. The root is the only part of the plant from which the characteristic extract is obtained.
Home: The Sierra Gorda in Querétaro
Chilcuague is endemic — it grows exclusively in the Sierra Gorda, Querétaro, Mexico. No other region in the world. In the limestone hills of this mountain range, in dry, rocky microhabitats, Heliopsis longipes thrives wild. Nowhere else.
This uniqueness makes Chilcuague an exceptionally rare botanical substance — there is no substitute, no alternative, no other region where more could simply be planted.
Active ingredient: Affinin
The tingling has a name: Affinin (N-Isobutyldodecatetraenamide). An alkylamide from the same class of compounds found in some Echinacea species. Particularly highly concentrated in the Chilcuague root, fat-soluble — and therefore much better extracted with alcohol than with water.
A treasure under pressure: Wild harvesting and sustainability
Because Heliopsis longipes occurs only in the wild in the Sierra Gorda, overharvesting is a real problem. YOMERA sources its Chilcuague directly from Mexico, from partners who know the plant’s rhythm — the right amounts, at the right time, with respect for what the plant population can sustain.
Traditional use
Indigenous communities — including the Huastec and the Otomi— have used the root for centuries for oral care and dental hygiene. The fresh or dried root was chewed to deliver the active compounds directly to the lining of the mouth. In Mexico’s shamanic traditions, Chilcuague is also regarded as a companion plant in ceremonies — its intense, noticeable effect in the mouth gives it ritual significance.
The making of the extract: From root to bottle
Traditional maceration
After being cleaned and dried, the roots are soaked in high-proof ethanol. Affinin dissolves in alcohol far better than in water — this cold extraction takes several weeks, until the root has released its active compounds completely. Anyone who speeds up the process or chooses the wrong ratio will get an inferior result.
Modern extract and spray
After maceration, the filtrate is filtered and further processed. For highly concentrated extracts, the alcohol is also removed — until an intense, viscous plant extract is produced.
The YOMERA Chilcuague Spray turns this process into a format suitable for everyday use: extract in a spray bottle — precise application to the lining of the mouth and gums, direct and with no compromise on quality.
Two factors determine quality: harvest time of the root and extraction method. Synthetic imitations are not an alternative. The value lies in the real plant extract — and that begins with the right root, harvested at the right time.
The Chilcuague Spray from YOMERA is sourced directly from Mexico, from suppliers familiar with the plant and its region. Curious? yomera.de
