The term wood lover paralysis (WLP) refers to a temporary state of muscle weakness and/or paralysis that begins several hours after consuming certain types of magic mushrooms (aka psychedelic mushrooms or psilocybin mushrooms). The phenomenon appears to occur only after ingesting magic mushroom species that grow on wood, hence the name wood lover paralysis.
Despite many anecdotal reports of WLP, no controlled scientific studies have been conducted to find its cause. As a result, there is no consensus as to either the cause or solution to this longstanding problem.
In October of 2017, we summarized the available anecdotal reports about the symptoms and attempted treatments for WLP. Based on the information available, we concluded that there are four leading theories:
- Microbial (e.g., bacterial, fungal) contamination
- Chemical Side Effect
Below, we discuss one type of microbial contamination that could account for the observed WLP symptoms.
The Black Rot Hypothesis
Many varieties of wood loving mushrooms develop a black rot on their caps and stems. This rot is often described as blue-black in color. The bluish color is presumably caused by the rot damaging the mushroom resulting in the well-known blue bruising phenomenon.
The photo below shows one example of advanced (or severe) black rot on a sample of Psilocybe cyanesens mushroom fruiting bodies. One particularly interesting observation captured in the photo is the presence of an opaque white liquid that seems to accompany the development of the black material. What is this black material? What is the white liquid that seems to accompany the developing black rot as it spreads?
Black rot is a reasonable potential cause of WLP. The black rot is much more prevalent on wood-loving mushrooms like Psilocybe cyanesens and Psilocybe azurescens. These mushrooms are often harvested outdoors where they are likely to encounter microbes. This would explain why there are relatively few (if any) reports of WLP arising from indoor cultivated mushrooms such as Psilocybe cubensis. Arguably, controlled indoor conditions prevent contamination. Ultimately, preventing the contamination prevents the occurrence of WLP.
Lingering Questions and Proposed Experiments:
- For the same species of mushroom, could one control the presence of black rot? In other words, would it be possible to collect data from a group of subjects consuming one batch of mushrooms, varying only the presence or absence of the black rot?
- Is there any information available about consuming black rot enriched samples? Does that correlate with a high incidence of WLP?
- Has anyone cultured and identified the black material that affects Psilocybe cyanesens or Psilocybe azurescens? If so, is that species known to produce any compounds (proteins or small molecules) that cause the symptoms observed for WLP?
Tuesday I at approx. 1 1 / 8. I was paralyzed keep falling crawling. No mouth control. Arms leg neck. Was very intense. Took. Benadryl & lorazepam. Today is Friday I still dont feel right.
Ive notice that anything over a gram of wood lovers will cause paralysis. An 1/8th?! damn I bet you couldn’t walk lol. How much Benadryl did you take and how did you feel? You would need to continually take Benadryl at a dose relevant to how may shrooms u ate plus how much you weigh. And continue to take it into next day or as long as you are feeling the negative effects….which I don’t really recommend. There are other better treatment options. The Benadryl treatment was the first thing I ever tried that worked but it did not work… Read more »
Hi Barb! This is djbabyjesus. You may have seen me in such threads as “The Cure for Azurescens Paralysis” I’m the person that came up with the Diphenhydramine (Benadryl) treatment option, which does in fact provide some, but not 100% relief). I was surprised and excited to see you quote some of my posts from the chat forms. These posts however, are about 10 yrs old. I haven’t posted in a while but after reading your research in to Aeruginascin and its potential action at the 5HT3 receptor, my mind went ablaze. I went a head and started another thread… Read more »
A note about the The Black Rot Hypothesis. first of all, The paralysis occurs wether the mushrooms are damaged or not. So no black rot but I do have a possible explanation for why there are so few, but not zero, (Paul Stamets has experienced it from home grown cyans) reports of home grown WL’ers causing negative effects. At one point I noticed that the azures from some locations (private, out side of public parks) were less likely to cause the paralysis. These locations were visited often by me, and I never let them get very old or damaged… The… Read more »
So is it a genetic issue or only when on wood substrate?
This message is for Barbara Bauer: Thank you for your literary contributions. I just finished a ton of articles on PSR, which initiated in my quest to identify trichoderma over bruising. Then, I noticed you’re in Michigan too! The site’s content continues to be so beneficial for me. I’m always looking for fellow supports.
