Pennyroyal honey is a strong-mint monofloral produced from two mint-family pennyroyal plants — Mentha pulegium (European, the dominant Iberian poleo source) and Hedeoma pulegioides (American) — sold most commercially as Iberian poleo and protected under Tenerife's DOP.
Mentha pulegium (European pennyroyal) and Hedeoma pulegioides (American pennyroyal) are the source plants for one of the world's most distinctive mint-family monoflorals — Iberian poleo, with Portugal and Spain as the major commercial producers. The honey is part of the Tenerife DOP ("Miel de Tenerife"), one of the small handful of protected honey designations in the Spanish-speaking world. It is also the variety where the plant-vs-honey distinction matters most sharply in this cohort: pennyroyal essential oil is severely hepatotoxic, historically a dangerous abortifacient, regulated and warned-against by health authorities. The honey is a food product. The page does not blur that line.
Two distinct plant species — sharing common-name "pennyroyal" but belonging to different genera within the Lamiaceae (mint) family — produce pennyroyal monofloral honey:
Both are low-growing, spreading, aromatic herbs in the mint family, producing whorls of pale lavender or pink flowers in summer. Both have an unmistakable strong mint character that carries through into the floral nectar, producing one of the most assertively flavored monoflorals on the global honey shelf.
Iberian poleo is the heart of commercial production — Portugal and Spain support traditional monofloral pennyroyal harvest, with Portugal's Alentejo and Trás-os-Montes regions and Spain's western interior as the historical centers. The honey is part of the DOP Miel de Tenerife (Tenerife protected designation of origin), one of the small handful of formally protected Spanish honey designations.
The honey is medium amber with a strong, almost medicinal mint character on the palate — assertive enough that it divides consumers into "love it" and "doesn't work for me" camps with little middle ground. The character comes from aromatic compounds (related to but not identical to the pulegone-rich essential-oil compounds in the plant) that transfer into the nectar in modest concentration. The mentholated finish is the variety's signature.
Pennyroyal sits at the sharpest plant-vs-honey distinction in this cohort. See the disambiguation block immediately below — the oil and the honey are different products with different regulatory profiles and different histories, and the page treats that distinction as primary, not as a footnote.
Pennyroyal essential oil — the steam-distilled volatile fraction of Mentha pulegium leaf and stem tissue — is dominated by pulegone, a monoterpene ketone with documented severe hepatotoxicity in mammals. The oil has a long historical use as an abortifacient in folk-medical traditions, and that use has resulted in documented human fatalities when concentrated oil was consumed at internal doses. Pennyroyal essential oil is restricted or warned against by health authorities in multiple jurisdictions; it is not a casual herbal product.
This is a real and serious plant-tissue safety profile, and we will not soft-pedal it.
Pennyroyal honey is a different product. Bees collect floral nectar, not leaf and stem tissue. The aromatic compounds that transfer into the nectar are related to but not identical to the pulegone-rich essential oil chemistry, and they appear in nectar at concentrations several orders of magnitude lower than in the concentrated steam-distilled oil. Pennyroyal honey is a recognized food product in Iberian and Tenerife traditions, part of the DOP Miel de Tenerife protected designation, consumed at normal food quantities without documented adverse-event history of the kind associated with essential-oil ingestion.
The two products are not interchangeable, and we don't pretend either way:
The page leads with this distinction because the variety's reputation in English-language internet sources frequently blurs the line — pennyroyal-the-oil's history bleeds into pennyroyal-the-honey discussions in ways that produce both unwarranted alarm about the honey and unwarranted casual treatment of the oil. The Iberian and Tenerife producers who keep this monofloral alive know the distinction well; the page reflects their framing.
Pennyroyal is one of the most assertively flavored monoflorals on the global honey shelf — the mint character is genuinely strong, and the variety divides consumers.
A herbaceous-forward monofloral — closer in palate logic to an herbal infusion than to a typical floral honey.
Pennyroyal is unusual on the global honey shelf for the strength of its mint character, the formality of its protected designation, and the precision the page applies to keeping the oil and the honey clearly separated.
Pennyroyal carries an unusually direct mint signature from the floral nectar into the honey — stronger than most herbaceous monoflorals and unmistakable on the palate. The variety is genuinely divisive; people who love it love it, and others find it too assertive. There is no "subtle" reading of pennyroyal honey.
Tenerife pennyroyal honey is covered by the DOP Miel de Tenerife — one of the small handful of formally protected honey designations in the Spanish-speaking world. The DOP covers several Tenerife varietal honeys including pennyroyal alongside chestnut, Lotus, and other Canary Islands monoflorals. The formal protection is part of the variety's identity.
Pennyroyal occupies a stable niche in Portuguese and Spanish food culture — té de poleo (pennyroyal tea) is a traditional after-dinner digestive infusion, and pennyroyal honey is the parallel sweet expression of the same plant. The Iberian producers who keep the variety alive know the plant and its products in detail.
Pennyroyal essential oil is severely hepatotoxic and historically a dangerous abortifacient. Pennyroyal honey is a food product. The two share a plant; they do not share a safety profile. The page leads with this distinction because the variety's English-language internet reputation frequently blurs the line.
Poleo is the Iberian common name for both the plant and the honey, and the variety has occupied a stable niche in Portuguese and Spanish food and herbal-tea culture for centuries. Té de poleo (pennyroyal tea), made from carefully dried pennyroyal leaf at controlled concentrations, is a traditional after-dinner digestive infusion in both countries; the honey is a separate but parallel product line, sold by Iberian beekeepers as a strong-character regional monofloral.
The Denominación de Origen Protegida "Miel de Tenerife" — Tenerife protected designation of origin for honey — is one of the small handful of formally protected honey designations in the Spanish-speaking world. The DOP covers several distinct varietal honeys produced on the island, including poleo de Tenerife (Tenerife pennyroyal honey) alongside other Canary Islands varietal monoflorals (Castaño/chestnut, Tedera/Lotus, and others). The Tenerife pennyroyal honey is one of the more visible regional expressions of the variety in international specialty markets.
Production scale is modest globally. Portuguese and Spanish mainland pennyroyal honey moves largely through traditional regional markets and through specialty importers serving Iberian-cuisine retail. Tenerife pennyroyal moves through the Canary Islands tourist economy and through DOP-certified export channels.
If you produce pennyroyal honey— or know a beekeeper who does — we'd love to add them to the directory and surface their jars to readers who arrive here looking for the real thing.

Pennyroyal honey — the bee-foraged floral nectar product — is a recognized food in Iberian and Tenerife (DOP Miel de Tenerife) culinary traditions, consumed at normal food quantities. Pennyroyal essential oil — the steam-distilled volatile fraction of the plant's leaf and stem tissue — is a different product entirely: severely hepatotoxic, historically used and dangerous as an abortifacient, regulated or warned-against by multiple health authorities. The two share a plant; they do not share a safety profile. Bees collect floral nectar, not leaf or stem tissue, and the aromatic compounds that transfer into the honey appear at concentrations several orders of magnitude lower than the concentrated steam-distilled oil. The page's disambiguation block addresses this in more detail.
Strong, mentholated, almost medicinal — one of the most assertively flavored monoflorals on the global honey shelf. The mint character is direct and unmistakable from the entry, the middle carries a soft floral lift and a peppery support, and the finish is long and herbaceous. People who love it love it; people who don't, don't. There is no subtle reading. Medium amber color; medium body.
Portugal (Alentejo, Trás-os-Montes), Spain (western interior), and Tenerife in the Canary Islands are the major producing regions. Tenerife pennyroyal honey is covered by the DOP Miel de Tenerife protected designation. American pennyroyal honey (from Hedeoma pulegioides in eastern North America) is produced at much smaller scale and travels less commercially.
No. Pennyroyal tea (té de poleo in Iberian Spanish) is a hot-water infusion of carefully dried pennyroyal leaf at controlled concentrations — a traditional after-dinner digestive in Portuguese and Spanish culture. The leaf carries the same pulegone-rich essential-oil chemistry that drives the concentrated steam-distilled oil's toxicity, so even leaf-tea uses are typically at modest concentrations and short infusion times by traditional practice. Pennyroyal honey is a separate product made from the floral nectar, with different chemistry and a different safety profile.
The Denominación de Origen Protegida "Miel de Tenerife" — Tenerife protected designation of origin for honey — is one of the small handful of formally protected honey designations in the Spanish-speaking world. The DOP covers several distinct Tenerife varietal honeys including pennyroyal (poleo de Tenerife) alongside chestnut (castaño), Tedera (Lotus), and other Canary Islands monoflorals. The DOP framework provides legal protection for the regional product against mislabeling.
European pennyroyal honey (Mentha pulegium) is by far the more commercially significant product — Iberian, Tenerife, and broader Mediterranean origin. The variety's formal Spanish DOP protection and its tradition in Portuguese and Spanish food culture trace to M. pulegium. American pennyroyal (Hedeoma pulegioides) is a different genus in the same Lamiaceae family, native to eastern North America, with a much smaller monofloral honey footprint. Both produce strong mint-character honey, but if a producer names "pennyroyal" without further specification in international specialty retail, M. pulegium is overwhelmingly the source.
