The Nepalese Honey That Makes People Hallucinate

Nepal’s Gurung people live mostly in small villages in the vast Annapurna mountain ranges. In this remote region, they practice an ancient tradition of honey hunting where they descend towering cliffs on handmade ladders, to harvest honey nestled under jagged overhangs. In spring, the Gurung’s honey contains a rare substance called grayanotoxin from rhododendron flowers that’s known for its intoxicating effects. While some accounts say it’s a deadly poison, others refer to it as an aphrodisiac, powerful medicine, and a hallucinogenic drug. This documentary is taken travelled deep into the Annapurna mountains to join a Gurung village on their spring hunt and understand Mad Honey’s effects.

In the mountains of Nepal, the region of Turkey closest to the Black Sea, the Pacific Northwest of the United States, and a handful of other locales around the globe, bees produce a particularly potent type of honey. It looks and tastes a lot different from the stuff you might squeeze out of a bear-shaped bottle. More importantly, though, it has a little more of a hallucinogenic effect than your average honey. To put it mildly, just one spoonful can get you as fucked up as a football bat.

Known to cause nausea, dizziness, and vomiting, this so-called mad honey is reddish in color and bitter in taste. As such, there’s little chance that you’d consume it by accident, and in fact, many people seek it out and pay a premium for it. As National Geographic reports, some harvesters risk their lives to raid beehives for the honey. Devotees say it has medicinal benefits, claiming that it helps with arthritis and sexual performance, among other things.
Mad honey is made by bees that feed on rhododendron flowers, which give it its psychoactive effects. Rhododendrons, evergreen flowering plants that grow in temperate, mountainous areas around the world, contain chemicals called grayanotoxins.


These neurotoxic compounds are cyclic diterpenes that exist in varying concentrations and varieties, depending on the particular rhododendron species and the time of year. Scientists have identified more than 25 types of grayanotoxins in rhododendrons. These chemicals make their way into the honey of bees that are feeding primarily on rhododendrons during the late spring, when so many of the plants are flowering that the bees can feast solely on rhododendron flowers without foraging elsewhere. In fact, some Turkish beekeepers even place their bee hives near rhododendron groves so that the bees will forage there, according to Modern Farmer.

Grayanotoxins, whether consumed in mad honey or in any part of the rhododendron, work in the human body by binding to voltage-gated sodium ion channels in cells. This keeps the channels from closing quickly, explains forensic toxicologist Justin Brower in his blog, Nature’s Poisons]

“The result is a state of depolarization in which sodium ions are freely flowing into the cells, and calcium influx is on the rise. The increase in calcium stimulates the release of acetylcholine,” he writes.

This acetylcholine excess causes what’s known as a cholinergic syndrome, which results in a set of symptoms known by their toxicology acronym, SLUDGE: Salivation, Lacrimation (crying), Urination, Defecation, Gastrointestinal distress, and Emesis (vomiting). In low to moderate doses, it’s known to cause heart rate and blood pressure to drop, and in high enough doses it can theoretically kill you, though there seem to be few reported cases of death from mad honey.

Like other traditional medicines, the rationale behind mad honey is as mythical as it is scientific. There’s a story that the army of the Persian King Mithridates defeated its Roman foes by littering the road with enticing mad honey honeycombs. According to this millennia-old story, the invading troops ate the honey and were easily defeated while under the influence of its intoxicating effects.

Experienced users know that a small amount is all that’s needed, especially since a substance like mad honey possesses its toxins in unknown concentrations. Others, like members of the message boards of Erowid, a community notorious for experimentation, strongly recommend against consuming rhododendron components.

It’s not just intoxication that people seek from it, though. As stated before, many people claim that mad honey offers relief from arthritis and helps enhance sexual performance. Like many traditional medicines, there isn’t a wealth of experimental data or clinical trials to back up these claims, but in recent years there is some evidence to suggest that they’re not too farfetched.

Researchers have found some evidence that suggests that grayanotoxin-containing preparations could help with hypertension, diabetes, high cholesterol, and even cold sores. These are just preliminary studies, though, and as such should not be taken as evidence that mad honey is safe or effective.

Medical remedies aside, if you’re searching for that next great high, mad honey is probably not the best place to look. Perhaps we can suggest something a bit more reliable.
