History and culture

 

This History and culture section is a stub.

As a result, it may contain incomplete or wrong information. You can help by expanding it.

Grayanotoxins are an active constituent of a variety of plants with a history of medicinal and recreational use, including species of rhododendron and monotropa uniflora [1]. Most commonly, grayanotoxins are consumed in the form of mad honey, which is contaminated with grayanotoxins from bees that pollinate rhododendron flowers [2]. Mad honey is reportedly used as an aphrodisiac, painkiller, treatment for hypertension, and as a recreational drug, particularly in Nepal and the Black Sea region of Turkey [2]. Historically, mad honey has been added to alcoholic drinks to increase their potency [3].

The Gurung people of Nepal are especially known to harvest mad honey for its supposed hallucinogenic properties [4].

Pharmacology

 

This pharmacology section is incomplete.

You can help by adding to it.

Grayanotoxins are a group of toxic diterpenes found in the ericacaeae family of plants [5]. More than 25 grayanotoxin isoforms have been isolated from rhododendron, though grayanotoxin I and grayanotoxin III are considered to be the most responsible for the toxic pharmacological effects of grayanotoxin-containing plants.[6] Grayanotoxin I, as well as grayanotoxin III, act as agonists of voltage-gated sodium channels.[7][8] Through this mechanism, grayanotoxins increase the release of neurotransmitters in the central nervous system such as GABA [8], glutamate [8], and acetylcholine [9].

Additionally, grayanotoxin III may act as an antagonist of central glutamate receptors, further contributing to CNS depressant effects [10]. Reports of grayanotoxin intoxication include symptoms of the cholinergic toxidrome such as decreased heart rate, hypotension, and an altered mental status [5].

Subjective effects

 
 This subjective effects section is a stub.

As such, it is still in progress and may contain incomplete or wrong information.

You can help by expanding or correcting it.

Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), an open research literature based on anecdotal user reports and the personal analyses of PsychonautWiki contributors. As a result, they should be viewed with a healthy degree of skepticism.

It is also worth noting that these effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects. Likewise, adverse effects become increasingly likely with higher doses and may include addiction, severe injury, or death ☠.

Dangerous interactions

 

This dangerous interactions section is a stub.

As such, it may contain incomplete or invalid information. You can help by expanding upon or correcting it.

Warning: Many psychoactive substances that are reasonably safe to use on their own can suddenly become dangerous and even life-threatening when combined with certain other substances. The following list provides some known dangerous interactions (although it is not guaranteed to include all of them).

Always conduct independent research (e.g. Google, DuckDuckGo, PubMed) to ensure that a combination of two or more substances is safe to consume. Some of the listed interactions have been sourced from TripSit.
