I thought "toxic honeys" was quite an interesting subject.
They are well know and recorded. The toxin is a grayanotoxin causing breathing and hypnotic (hallucinogenic) episodes. Been reported in Asia Minor, Himalayas (remember those cliff dangling honey hunters), Southern Russia, Eastern United States, Pacific Northwest and a few other locales.
What is of interest is the effects vary depending on the amount consumed (not surprising).
In Turkey "Del Bali" as it is called is the addition of a small amount of toxic honey to milk or alcohol,to produce enhanced effects. It was a major export to Europe in the 18th century. About 25 tons of "toxic" honey per year was shipped. Called miel fou (mad honey) that was added to drinks sold in taverns.
It is though "mad Honey may have been the driver of the prophesies of the Pythia of Delphi.
There's a lot more but that is the distillate.
Hope some of you find it of interest.
