How Do We Actually Know Siberian Shamans Used Fly Agaric? The Sources, Named

"Ancient Siberian Shamans Used It" — But How Do We Actually Know That?

Nearly every Amanita muscaria article asserts that Siberian shamans used the mushroom ritually. The claim is broadly true. What almost none of them do is say where that knowledge actually comes from — which specific documents, written by whom, when, and how reliable those documents are once you look at the circumstances under which each was written. The answer is a surprisingly small set of sources. Some of them are secondhand, and knowing which is which changes how confidently any particular detail should be stated.

The Actual Documentary Record

The modern picture of Siberian fly agaric use rests substantially on a handful of accounts. Filip Johann von Strahlenberg, a Swedish officer held prisoner in Siberia for thirteen years, published the earliest widely-circulated description in 1730, including the mushroom's use among the Koryak. Stepan Krasheninnikov, who spent roughly three and a half years in Kamchatka with the Second Kamchatka Expedition, published his description of the region in 1755 — the strongest eyewitness-grade early source, describing preparation methods, rough dosing, and a trade in mushrooms from Itelmen to Koryak territory. Carl von Ditmar traveled Kamchatka in the 1850s, though his account wasn't published until decades later.

The most methodologically solid material is considerably later. Waldemar Jochelson and Vladimir Bogoras both conducted professional ethnographic fieldwork during the Jesup North Pacific Expedition around 1900-1902, producing detailed monographs on the Koryak and the Chukchi respectively. Their work is fieldwork by trained ethnographers rather than travel observation by soldiers and naturalists, and it's the closest thing to a rigorous baseline the record offers.

A Detail Worth Noticing About the Earliest Source

Strahlenberg is the account most often cited as the origin point, and there's a specific problem with how it's usually invoked. His thirteen years of captivity were spent in western Siberia, around Tobolsk — not in Kamchatka or Koryak territory, thousands of kilometers to the northeast. So his description of Koryak practice was almost certainly gathered from reports rather than witnessed directly. That doesn't make it worthless. Later fieldwork corroborated the general practice, and an early secondhand account that turns out to be broadly accurate is still evidence of something. It does mean the foundational text of this entire tradition is a secondhand account presented, in most modern retellings, as though it were direct observation.

How did the Siberian reports reach Western readers?

Few people in Britain or western Europe read the first accounts in their original language. Strahlenberg wrote in German, and his book reached English readers through a London translation of 1736, with a further printing in 1738. In the English text the fly agaric passage is a single paragraph about the Koryak inside a long geographical survey. It says that Russian traders brought them a mushroom called "muchumor" in exchange for furs, that wealthier households stored it for the winter and drank the liquid from boiled mushrooms at feasts, and that poorer people drank the urine of those who had taken it.

Krasheninnikov's Russian account of 1755 took the same route. An English translation by James Grieve was printed in 1764, and the translator's preface states plainly that the part covering the manners, customs and religion of the people "has been most considerably abridged". English readers therefore met the strongest early eyewitness source in shortened form, with the ethnographic sections cut hardest. The fly agaric passage survived, including the statement that the Koryak bought the mushroom from the Kamchadals because it did not grow in their own country.

The popular phase came a century later. In 1860 the British mycologist Mordecai Cubitt Cooke published The Seven Sisters of Sleep, a general history of what he called the seven prevailing narcotics of the world. Its dedication greets "all swallowers of amanita, either in Siberia or elsewhere", and a chapter titled "The Exile of Siberia" retells Krasheninnikov's description alongside anecdotes from other writers. Cooke's book is a compilation rather than new evidence. What it shows is that, by the mid-Victorian period, the Kamchatka reports had become a familiar set piece in English writing about intoxicants.

In the twentieth century the best fieldwork reached Western readers directly: Jochelson's Koryak monograph was published in English by the American Museum of Natural History. In 1967 R. Gordon Wasson gathered the scattered travellers' reports in one English-language survey, "Fly Agaric and Man", and went on to link them to his theory that the mushroom was the Vedic Soma. How historians weigh those early travellers, and how details were copied from book to book, is set out in our article on fly agaric across cultures.

The Practice Was Concentrated, Not Pan-Siberian

Content describing fly agaric use as broadly "Siberian," or as having influenced Indo-European cultures generally, overstates the documented geography considerably. The well-attested core is northeastern: the Koryak, Chukchi, and Itelmen of the Chukotko-Kamchatkan region, where the practice is densely documented. There's a second, separate western cluster among the Ob-Ugrian peoples — the Khanty and Mansi — but scholarship characterizes that use as sporadic rather than central, one technique among several including drumming and dancing, and among the Khanty it's notably tied to epic-song performance rather than to classic shamanic journeying.

Between those two clusters is a large geographic gap. Claims extending the practice to other Siberian peoples are thin enough that they shouldn't be asserted without a specific citation. And the leap from "documented among several northeastern Siberian peoples" to "woven into the fabric of human civilization" is a rhetorical move, not a historical finding — the kind of quiet inflation that turns a real, specific, regionally-bounded ethnographic fact into a vague claim about all of human history.

Is there reliable evidence of use outside Siberia?

Not of the same quality. Claims about fly agaric use elsewhere fall into three groups, and each rests on a thinner or different kind of evidence than the Siberian record, where several independent writers over two centuries describe the same practice.

North America. In 1979 the Journal of Psychedelic Drugs printed a short paper by Wasson on traditional divinatory use in North America, and in the same issue "The legend of Miskwedo" by Keewaydinoquay. These are the accounts most often cited for North American use. They appeared more than two centuries after the first Siberian reports, and we have not found older travellers' or ethnographers' records that would let them be cross-checked in the way Jochelson and Bogoras confirmed the earlier Siberian accounts. That does not show the reports are wrong. It does mean the evidence is weak and should be described that way.

Scandinavia. The story that Viking berserkers ate fly agaric before battle is the best known claim and among the least supported. A 2019 review argued that henbane fits the saga descriptions better, while stressing that there is not enough archaeological and historical evidence to prove or disprove any of the theories (Fatur, Journal of Ethnopharmacology, 2019). Our article on fly agaric in Northern European folk history looks at the berserker story and other Nordic claims.

Eastern Europe. Here the evidence is real but recent, and it concerns folk medicine rather than intoxication. A 2024 study combined 35 historical written sources with 581 interviews in eight countries on the western borderlands of the former Soviet Union (Prakofjewa et al., IMA Fungus, 2024). Fly agaric was one of only six fungi named both in pre-Soviet sources and by people interviewed, and the same six were consistently endorsed in Soviet herbals. The authors concluded that written sources strongly shaped which fungi people used, so "folk" knowledge recorded today may have been learned from books. The study recorded what people reported; it did not test whether any of it worked.

Archaeological claims sit apart from all three. The rock carvings in Chukotka often read as mushroom figures, and the old Siberian trade in dried caps, are covered in our article on what traditional preparation actually looked like. Put plainly: use among particular Siberian peoples is documented; use elsewhere ranges from recent and thin to speculative.

The Urine Claim: Split It in Two

The famous urine-recycling detail deserves separating into two claims with very different evidentiary standing. Human urine recycling — the practice of conserving the active compounds by drinking the urine of someone who had consumed the mushroom — is genuinely well-attested, reported independently by Strahlenberg and Krasheninnikov and later confirmed by both Jochelson and Bogoras. That one can be stated as documented.

The reindeer version, in which reindeer eat the mushrooms and humans then drink reindeer urine, is on much weaker ground. Scholar Andy Letcher examined the historical record and found no supporting evidence for it, characterizing it as a modern invention rather than a documented Siberian practice. It circulates anyway. It's a memorable detail attached to the Santa Claus story, which this site has checked separately — but memorable and documented are different properties, and this is a case where the more entertaining version has almost entirely displaced the sourced one in popular retellings.

What the Narrowness of the Record Actually Implies

There's a scholarly position worth knowing that rarely surfaces in popular content: Harri Nyberg's comparative work concluded that, unlike psilocybin mushrooms in Mesoamerica, fly agaric does not appear to have been an object of religious or ritual veneration in northern Eurasia in the same sense. More broadly, specialists in North Asian shamanism have generally held that drug use was not central to the practice. That's a meaningful corrective to content presenting the mushroom as the engine of Siberian spiritual life — and it coexists with the fact that documented ritual use genuinely did occur among specific peoples. Both things are true, and popular writing tends to keep only the more dramatic half.

Frequently Asked Questions

Bottom Line

Siberian ritual use of Amanita muscaria is real and documented, but it rests on a narrow source base worth knowing by name: a likely-secondhand 1730 account, a strong 1755 eyewitness description, and professional ethnographic fieldwork from around 1900. The practice was concentrated among specific northeastern peoples rather than pan-Siberian, human urine recycling is well-attested while the reindeer version isn't, and serious scholarship disputes the idea that the mushroom was central to Siberian shamanism at all.

Our piece on Wasson's Soma hypothesis applies the same source-checking approach to the most academically serious mythological claim about this mushroom.
