Amanita Muscaria and Anxiety: What the Evidence Actually Shows
There is no clinical evidence that Amanita muscaria reduces anxiety. No human trial has tested it for that purpose. The evidence that does exist comes from poisoning case reports, and those reports list agitation, paranoia, confusion and panic-like symptoms as side effects. Anxiety has effective, well-studied treatments, and they are a far safer place to start.
An earlier version of this page described "anecdotal anxiety reduction" and recommended supplements as alternatives. We have replaced it with a plain summary of what the research record actually contains.
Has Amanita muscaria ever been tested for anxiety?
No. We could not find a single controlled human trial of Amanita muscaria, or of purified muscimol, as a treatment for any anxiety disorder.
The idea rests on pharmacology. Muscimol acts on GABA-A receptors, the brain's main inhibitory system (Michelot & Melendez-Howell, Mycological Research, 2003). The mushroom also contains ibotenic acid, which excites neurons rather than calming them. The balance between the two varies from mushroom to mushroom.
Online reports of feeling calmer are not a substitute for trials. A 2024 review of psychedelic research showed how strongly expectation shapes what people report, even in formal studies (Expectancy Effects in Psychedelic Trials, 2024). Informal anecdotes have no blinding and no control group, so the problem is larger still.
What do the case reports show?
The human record for Amanita muscaria is mostly hospital case reports. They describe effects that run in the opposite direction to calm.
- A 2025 report from Lithuania described patients with agitation, paranoia and disorientation, some of whom needed sedation. Severe cases needed a ventilator (Savickaitė & Laubner-Sakalauskienė, Acta Medica Lituanica, 2025).
- A 2025 literature review in Toxins described confusion, vertigo, hallucinations, seizures and, in severe cases, coma (Acute Amanita muscaria Toxicity, Toxins, 2025).
- A published case series in Wilderness & Environmental Medicine documented a death after ingestion (Meisel et al., 2022).
The US FDA reviewed more than 600 publications in 2024. It concluded that Amanita muscaria and its constituents are not generally recognised as safe in food (FDA Scientific Memorandum, September 2024).
Our overview of what the Amanita adverse-event record contains covers these reports in more detail.
Why are anxiety and early poisoning hard to tell apart?
Anxiety causes a racing heart, sweating, dizziness, nausea and a sense that something is wrong. Early Amanita poisoning can cause many of the same things.
For someone who already lives with anxiety, that overlap is a real hazard. They may dismiss poisoning as "just my anxiety" and wait too long for help. Or a toxic reaction may trigger a panic attack on top of the physical symptoms.
Timing adds to the confusion. Reported symptoms often begin within a couple of hours, but they can fluctuate between drowsiness and agitation. That unpredictable pattern is the opposite of what someone with anxiety needs.
What are the evidence-based options?
Anxiety disorders are common and treatable. NIMH names CBT as the "gold standard" psychotherapy for generalised anxiety, alongside medicines such as SSRIs, SNRIs and buspirone (NIMH, Generalized Anxiety Disorder, 2025). NIMH adds that exercise, mindfulness and meditation can reduce symptoms when combined with standard care.
In the UK, the NICE guideline recommends a stepped approach, from guided self-help to CBT or applied relaxation, then medication where needed (NICE CG113, 2011, updated 2020).
One safety note applies to anyone already taking a benzodiazepine. In 2020 the FDA warned that stopping these medicines abruptly can cause withdrawal reactions, including life-threatening seizures (FDA Drug Safety Communication, 2020). Never swap a prescribed anxiety medicine for anything else without your prescriber.
Muscimol's receptor action is often compared to these medicines. Our article on which receptor subtype muscimol prefers explains why that comparison is less neat than it sounds.
Getting help
- Emergency or suspected poisoning: contact your local emergency services (911 in the US, 999 in the UK, 112 in the EU). In the US, Poison Help is 1-800-222-1222, free and 24/7. In the UK, call NHS 111.
- Anxiety crisis (US): call or text 988, the Suicide & Crisis Lifeline.
- Ongoing anxiety: speak to your GP or family doctor. In England you can refer yourself to NHS Talking Therapies.
Frequently Asked Questions
Is there any clinical trial of Amanita muscaria for anxiety?
No. We found no controlled human trial of Amanita muscaria or muscimol for any anxiety disorder. Claims rest on receptor pharmacology and anecdotes.
Can Amanita muscaria cause anxiety?
Case reports describe agitation, paranoia, disorientation and confusion after ingestion. These effects can feel very similar to a panic attack.
Why does muscimol get compared to anti-anxiety medicines?
Because both act on GABA-A receptors. Sharing a receptor system does not mean a substance is safe or effective, and muscimol has never been tested for anxiety.
What does the FDA say about Amanita muscaria?
In a September 2024 memorandum, the FDA concluded that Amanita muscaria and its constituents are not generally recognised as safe for use in food.
What should I try instead?
Speak to a doctor about proven options such as CBT, applied relaxation or medication. Exercise, sleep and mindfulness can support that care.
