Episode 98: Blue-Staining Bolete Mushrooms - The Mystery of Lilliputian Hallucinations
This week on The Tox Lab, we're exploring blue-staining bolete mushrooms and the fascinating phenomenon of Lilliputian hallucinations.We take a look at Lanmaoa asiatica, a mushroom found in Yunnan Province, China, which has been associated with unusual neuropsychiatric effects following ingestion. We discuss reported cases of mushroom poisoning after undercooked or raw mushroom ingestion and the gastrointestinal symptoms and vivid visual hallucinations that can occur.We then explore Lilliputian hallucinations, a distinctive type of visual hallucination in which people perceive tiny human or fantasy figures. From miniature people behaving as though they are interacting with the real world to reports of tiny animals and colourful characters, we look at how these experiences are described in the literature and explore the wider range of psychiatric, neurological and other conditions associated with them.Finally, we look at the ongoing search for the compound responsible for the hallucinations associated with Lanmaoa asiatica. We discuss recent research into the mushroom, including the identification of two previously unreported pyrrole alkaloids, and consider whether these could offer clues to the unusual effects.Join us as we explore mushroom poisoning, Lilliputian hallucinations and the search for the compound behind one of the more unusual presentations in mushroom toxicology.Hope you enjoy!Editor's note: You may notice Rob's cold getting increasingly involved in the conversation as the episode progresses.

Episode 93: Psychedelic Therapy: Psilocybin, Depression and the Evidence
This week on The Tox Lab, we're diving into the world of psychedelic therapies and exploring the use of psilocybin to treat depression.We begin with a recent trial investigating whether psilocybin-assisted therapy could actually be delivered within an NHS setting. We explore the practical challenges of delivering psychedelic therapy, the results of the trial, and what the findings might mean for the future of psilocybin treatment for people with treatment-resistant depression.We then look at how psilocybin could produce antidepressant effects that persist long after the drug itself has left the body. We discuss what happens when psilocybin is converted to psilocin, its effects on serotonin receptors, and some of the proposed mechanisms behind its longer-term effects, including changes in brain activity, connectivity and neuroplasticity.Finally, we examine the evidence from a trial comparing psilocybin with escitalopram, asking how the two treatments compare and what this tells us about the potential role of psilocybin in treating depression. We also discuss one of the fundamental challenges in psychedelic research: can you really blind a trial when participants can often tell whether they've received a psychedelic?Join us as we explore the science behind psychedelic therapy, the evidence for psilocybin in depression, and the challenges of moving these treatments from clinical trials into real-world healthcare.Hope you enjoy!Links to the papers we discussed:https://www.nature.com/articles/s41591-026-04541-0 https://www.nejm.org/doi/full/10.1056/NEJMoa2032994 Disclaimer: All opinions are our own.Find us on instagram: @the_tox_labEmail us here: thetoxlab@gmail.comCheck out our new website: https://thetoxlab.co.uk/ Support us here: https://buymeacoffee.com/thetoxlab

Episode 92: Mad Honey - Grayanotoxins and Cardiovascular Effects
This week on The Tox Lab, we're diving into the world of mad honey and grayanotoxin poisoning.We examine where mad honey comes from and its cultural uses before turning to the compounds responsible for its toxic effects: grayanotoxins. We discuss how these compounds affect voltage-gated sodium channels and how this can lead to severe bradycardia, hypotension, cardiac conduction abnormalities, dizziness, neurological symptoms and, in some cases, hallucinations.The episode also examines reported cases of mad honey poisoning, including a severe case in Nepal and a case from the UK involving imported raw honey. We consider why the concentration of grayanotoxins can make the effects of mad honey difficult to predict and explore the clinical features of grayanotoxin poisoning.Join us as we explore the chemistry, pharmacology, history and toxicology of mad honey, and discover how something as familiar as honey can cause significant cardiovascular and neurological toxicity.Hope you enjoy!Links to the papers we discussed:https://pmc.ncbi.nlm.nih.gov/articles/PMC9978999/pdf/EFS2-21-e07866.pdf https://www.mdpi.com/1420-3049/30/19/3925 https://analyticalsciencejournals.onlinelibrary.wiley.com/doi/10.1002/jat.4855 https://pmc.ncbi.nlm.nih.gov/articles/PMC6293183/pdf/CCR3-6-2355.pdf https://www.cureus.com/articles/488288-mad-honey-poisoning-caused-by-grayanotoxin-toxicity-in-a-75-year-old-male-patient-presenting-with-hypotension-and-bradycardia-in-the-united-kingdom-a-case-report#!/ Disclaimer: All opinions are our own.Find us on instagram: @the_tox_labEmail us here: thetoxlab@gmail.comCheck out our new website: https://thetoxlab.co.uk/ Support us here: https://buymeacoffee.com/thetoxlab
