About
Solanum mauritianum is a small tree or shrub native to South America, including Northern Argentina, Southern Brazil, Paraguay and Uruguay. Its common names include earleaf nightshade (or "ear-leaved nightshade"), woolly nightshade, flannel weed, bugweed, tobacco weed, tobacco bush, wild tobacco and kerosene plant.
Safety
It is alleged that all parts of the Solanum mauritianum plant are poisonous to humans, especially the unripe berries, and furthermore that human fatalities have resulted from the consumption of the berries, and cases of fatal poisoning in pigs and illness in cattle have been reported in Queensland.
However, mountain possums appear to eat it without ill effect, and stripping of bark, leaves, and terminal shoots has destroyed pure stands of S.mauritianum. Watt & Brandwijk state that horses, domestic chickens and all birds eat the fruit with impunity, and further state that no records of poisoning in children exist, casting doubt on contrary published accounts.
