Among the potentially murderous or mind-altering flora are datura, oleander, narcissus and pennyroyal.

Second, ground-up seeds from the Datura plant which acts as a sedative and causes hallucinations were discovered.

In November an international research team revealed that chewed-up wads of datura, a plant that acts as a deliriant, had been found jammed in the ceiling cracks of a location known as Pinwheel Cave.

Now the remains have been confirmed as Datura, a plant used historically for its psychoactive effects.

While many have believed that prehistoric rock art was influenced by hallucinogens, this latest research suggests that the rock paintings at Pinwheel Cave depicted the Datura plant itself, rather than any visions caused by the plant, the study said.
