what is the name of the poison isolated from Duscle garden nightshade?
Solanum nigrum European black nightshade ("Solanum nigrum") or locally just black nightshade, duscle, garden nightshade, garden huckleberry, hound's berry, petty morel, wonder berry, small-fruited black nightshade, or popolo) is a species in the "Solanum" genus, native to Eurasia and introduced in the Americas, Australasia, and South Africa. Parts of this plant can be toxic to livestock and humans. Nonetheless, ripe berries and cooked leaves of edible strains are used as food in some locales, and plant parts are used as a traditional medicine. A tendency exists in literature to incorrectly refer to many of the other "black nightshade" species as ""Solanum nigrum"".
Rubroboletus satanas Rubroboletus satanas, commonly known as the Satan's bolete or Devil's boletus is a basidiomycete fungus of the bolete family. It was known scientifically as Boletus satanas until 2014. Found on chalky soil in mixed woodlands in the southern, warmer regions of Europe, it is generally regarded as a poisonous mushroom, with predominantly gastrointestinal symptoms of nausea and violent vomiting occurring if eaten raw or fried. However, reports of poisoning are rare due to its odd appearance and at times putrid smell minimising casual experimentation. There are reports of its traditional consumption in the former Czechoslovakia and Italy after thorough cooking (frying does not remove the toxin).
