When you give the video url to Grok, what query do you type in? "Fact check this video" or what?
Wikipedia (regularly fact checked by humans) says the mushroom really does make you see little people. So AI (even Grok) can't be fully trusted either.
It is a type of hallucinogenic bolete mushroom and is notable for causing lilliputian hallucinations (little people hallucinations) when eaten raw.

Just tell it to fact check this video with the video title and provide the YT link.
Even ChatGPT give similiar replies:
This is a
great critical analysis — and you’re right to question sensational claims, especially viral internet videos. Let’s unpack the scientific truth about
Lanmaoa asiatica and the viral “tiny people” claim carefully.
What is Lanmaoa asiatica?
Lanmaoa asiatica is a
species of bolete mushroom found in parts of China (especially Yunnan), related to:
✔ Boletus edulis (porcini / cep)
✔ Other edible boletes
It is generally considered a
culinary mushroom when properly identified and cooked — not a classic hallucinogenic species like
Psilocybe or
Amanita muscaria.
There is
no credible scientific source that it contains known hallucinogens such as:
psilocybin
muscimol
ibotenic acid
DMT / other indole alkaloids
Extensive chemical screens of boletes typically
do not find psychedelic compounds in these mushrooms. If you search peer-reviewed databases (PubMed, CNKI, Scopus),
you won’t find a published toxicology report linking Lanmaoa asiatica to hallucinations.
What about the “tiny people” stories?
The short answer is:
There are no documented medical or scientific cases of people seeing tiny people after eating this mushroom.
No hospital records or peer-reviewed reports support this.

The story has spread mainly via
short-form social media (TikTok, Douyin, YouTube shorts, Xiaohongshu) as sensational content.
The pattern is typical of modern online misinformation:
- Anonymous claim/video → “I ate this and saw little people”
- Reposts and sensational titles
- Algorithm amplification + no real evidence
- Viewers assume it must be true or mysterious
This matches viral folklore more than verified science.
What real effects undercooked or misidentified boletes can cause
The actual medically observed effects of eating wild boletes improperly are:
Gastrointestinal upset
- nausea
- vomiting
- diarrhea
- cramps
This can happen with:
- misidentification (picking the wrong species)
- eating raw/undercooked mushrooms
- individual food sensitivity
Not hallucinations
There is
no credible evidence that Lanmaoa asiatica causes visual hallucinations — tiny people or otherwise.
In cases of hallucinogenic experiences reported in hospitals, it’s usually:
✔ Drug intoxication (intentional or accidental)
✔ Anticholinergic poisoning
✔ Delirium from fever or infection
✔ Other known neuroactive substances
These are well-documented in medical literature — again,
not linked to this mushroom.
How reliable claims spread
In folklore and online culture, mushrooms have long been surrounded by myths:
- fairy tales of elves and sprites
- Amanita muscaria “magic mushroom” lore
- exaggerated forest folklore
Online short videos often:
✔ conflate unrelated species
✔ misattribute experiences
✔ repeat sensational commentary
✔ lack verifiable evidence
So while the original video might claim “this mushroom makes you see little people,” that is
internet storytelling, not science.
How hallucinations actually occur
Clinical hallucinations (including so-called “lilliputian hallucinations” — seeing tiny people) can occur in some contexts, but not from this mushroom:
Known causes of lilliputian visuals:
✔ Charles Bonnet syndrome (vision loss + brain filling in imagery)
✔ Delirium (fever, infection, withdrawal)
✔ Certain medications (anticholinergics, high-dose stimulants)
✔ Psychiatric conditions
✔ Classic psychedelics (
psilocybin, LSD, DMT)
Medical literature on hallucinations does not list Lanmaoa asiatica as a cause.
What the viral narrative got wrong
Let’s match the claim to verified facts:
| Claim | Evidence? |
|---|
| Eating Lanmaoa asiatica causes tiny people hallucinations | No peer-reviewed evidence |
| Hospitals in Yunnan treat people for hallucinations from this mushroom | No documented medical case series |
| The mushroom contains unknown hallucinogens | Existing chemical screens show no known psychoactive compounds |
| Proper cooking removes the hallucinogenic effect | No evidence of hallucinogenic compounds to remove |
In contrast, the actual known risks are:
✔ misidentification poisoning
✔ gastrointestinal irritation
✔ allergic food reactions
Not psychedelic effects.
Final, evidence-based bottom line
No — there is no credible scientific evidence that Lanmaoa asiatica causes people to see tiny humanoid figures.
The viral internet claim is best described as:
social media myth
unverified anecdote
internet folklore
not supported by toxicology or clinical data
The mushroom itself is generally considered edible like other boletes when properly identified and cooked, and the only documented reactions are typical food poisoning or irritation —
not hallucinations.
