The history of mad honey — 2,500 years

The long arc

Mad honey is one of the few pharmacologically active foods whose written history spans more than two millennia. The pharmacology hasn't changed — the same Rhododendron species, the same grayanotoxins, the same human physiology. What has changed is the cultural framing: military hazard → traded commodity → scientific curiosity → folk medicine → Western wellness product. Each era understood the same molecule through a different lens.

401 BCE — Xenophon's soldiers

The earliest clear written account comes from Xenophon's Anabasis, the memoir of his leadership of ten thousand Greek mercenaries retreating through Persian Empire territory after the battle of Cunaxa. In Book IV, Chapter 8, Xenophon describes the army reaching the territory of the Heptakometes (in what is now northeastern Turkey's Trabzon region) and encountering local honey stores:

The soldiers who ate of the honeycombs lost their senses, and vomited and had diarrhea, and none of them could stand up; those who had eaten a little were like very drunken men, and those who had eaten a great deal were like mad men, and some like dying men. So they lay there in great numbers as if there had been a rout, and there was great despondency. But on the next day no one had died, and they recovered their senses at about the same hour; and on the third and fourth days they got up as if after a medical treatment.

This description is clinically precise enough that it maps cleanly onto modern grayanotoxin intoxication. See our full analysis in the Xenophon incident post. It is, effectively, the first clinical case report of any psychoactive food.

65 BCE — Pompey and biological warfare

The second mass-exposure incident is more deliberate. When Pompey the Great campaigned through Pontus against Mithridates VI in 65 BCE, local Heptakometes warriors left combs of mad honey along the Roman march route as a trap. Roman soldiers consumed the honey, became incapacitated, and were attacked and killed while unable to defend themselves. Strabo describes the incident in his Geographica.

This is arguably the earliest documented use of biological warfare. The tactic exploited two features of the pharmacology: grayanotoxin's delayed onset (30–90 minutes) and its incapacitating but not immediately lethal effect. Combatants would feel fine when they ate the bait and would only become symptomatic when it was too late.

The Silk Road era

Between the 2nd century BCE and the 15th century CE, mad honey moved along Silk Road trade routes between the Pontic coast, the Caucasus, Persia, and Central Asia. The product is mentioned in several Persian and Arabic pharmacological texts of the medieval Islamic world — typically as a trade good from the Pontic region, sometimes with medicinal claims attached. Ibn Sina (Avicenna) and other Islamic Golden Age authors catalogued it alongside other plant-derived medicines.

Trade volumes are impossible to reconstruct, but the product was known well enough to have a stable vocabulary across languages — Greek, Latin, Arabic, Persian, Turkish — which implies regular commerce.

Ottoman era

Under Ottoman rule (14th–20th c.), the Pontic coast became a stable trading region, and deli bal entered formal Ottoman pharmacopeia. It was used for hypertension (the vasodilation effect), for sleep aid, and — with more ambiguous results — as an alleged aphrodisiac. The traditional-use claims that survive in modern Turkish folk medicine largely originate in this period.

Notably, the Ottomans understood that excessive consumption was dangerous. Ottoman medical texts include explicit dosing guidance and warn against combining deli bal with certain other medicines. This represents one of the earliest written pharmacology protocols for the substance.

European scientific interest: 17th–19th centuries

Mad honey enters European scientific literature slowly. 17th-century travelogues from the Black Sea region mention it as a curiosity. In the 18th and 19th centuries, Western pharmacology began serious investigation.

Several notable moments:

• 1834 — Procter: First isolation of "andromedotoxin" (now called grayanotoxin) from Rhododendron maximum. The compound was characterized as a crystalline substance with cardiac effects.
• 1881 — Plugge: Dutch pharmacologist extended the chemistry, identifying the compound in multiple Ericaceae plants.
• 1931 — Moore and Wakeman: Established the structural relationship between grayanotoxin isoforms.

During this era, mad honey was primarily a scientific curiosity in Europe — not a commercial product in the West. The commercial trade remained regional to Turkey, the Caucasus, and Nepal.

The Nepalese tradition — ancient and unbroken

Parallel to the Turkish history, Nepal has its own uninterrupted mad-honey tradition. The Gurung honey-hunter ritual predates written record. Songs, community rights to specific cliff faces, and ritual observances around spring and autumn harvests have been passed down for at least ten generations — meaning the practice dates at minimum to the mid-18th century with all the features we still see today, and probably much earlier.

Nepalese mad honey did not enter global trade meaningfully until the 1970s–1980s, when trekking tourism brought foreign visitors into contact with the Gurung harvesting tradition. Our honey hunters pillar covers the ritual in detail.

20th century — documentation and diaspora

Several key events in the 20th century transformed the category:

• 1960s–70s: Academic pharmacology characterizes grayanotoxin's voltage-gated sodium-channel mechanism.
• 1980s–90s: Turkish medical literature begins publishing case-series data on deli-bal poisoning, giving the West a modern clinical picture.
• 1987: Eric Valli's photography documents the Nepalese honey-hunter tradition for a Western audience (National Geographic feature).
• 1990s–2000s: Gradual internet-era awareness in Western wellness circles.

2010s — the modern commercial category

Three factors drove the emergence of mad honey as a global commercial category between roughly 2015 and 2022:

1. Documentary media attention. The 2017 Ben Knight short film "The Last Honey Hunter" and earlier Best Ever Food Review Show episodes brought the Gurung harvest to YouTube audiences in the tens of millions.
2. Wellness culture shift. Growing Western interest in plant-based bioactives, traditional medicines, and "natural" pharmacology created receptive buyers.
3. DTC infrastructure. Shopify, international shipping, and social-media marketing made it economically feasible for small Nepalese/Turkish cooperatives to reach Western consumers directly, bypassing traditional import distribution.

By 2020, brands like Real Mad Honey, Stoned Mad Honey, and Mad Honey Supply (Yeti, Mad Turk) were operating at commercial scale in the US market. By 2024 the category had 15+ brands, hundreds of thousands of annual consumers, and a supply chain structure that paid fair-trade premiums to Nepalese honey hunters.

The counterfeiting wave

With commercial scale came counterfeiting. From roughly 2020 onward, Amazon and eBay marketplaces saw an influx of "mad honey" listings of ambiguous origin and questionable potency. In parallel, a separate but adjacent category emerged: male-enhancement honey packs containing undisclosed sildenafil and tadalafil, some marketed with mad-honey adjacency. These are tracked in detail by our sister site HoneyPackFinder. They are not mad honey but they share shelf space and consumer confusion.

Now — 2026

The category is maturing. Buyers increasingly demand lab documentation. Ethical brands are establishing direct cooperative relationships with Nepalese harvester communities. Regulatory authorities — particularly the EU, UK, and Canada — are formalizing novel-food assessments. Scientific interest in grayanotoxin pharmacology is slowly growing beyond the Turkish medical literature.

Where the category goes next depends on three pressures: climate change's effect on Himalayan Rhododendron bloom patterns, regulatory decisions in key markets, and whether counterfeit control can keep pace with commercial expansion. The underlying pharmacology hasn't changed in 2,500 years. The industry around it is still being built.

Bottom line

Mad honey has one of the most continuous written histories of any psychoactive food. The molecule is the same across 25 centuries. The human understanding of it has evolved from hazard to commodity to scientific curiosity to wellness product. Modern buyers inherit this long arc whether they know it or not — and understanding it makes the present category more legible.
