Atropa belladonna, commonly known as belladonna or deadly nightshade, is a perennial herbaceous plant in the family Solanaceae, native to Europe, North Africa, and Western Asia. The foliage and berries are extremely toxic, containing tropane alkaloids.
Folklore
In the past, it was believed that witches used a mixture of belladonna, opium poppy, and other plants, typically poisonous (such as monkshood and poison hemlock) in flying ointment they applied to help them fly to gatherings with other witches. Carlo Ginzburg and others have argued that flying ointments were preparations meant to encourage hallucinatory dreaming; a possible explanation for the inclusion of belladonna and opium poppy in flying ointments concerns the known antagonism between tropane alkaloids of belladonna (specifically scopolamine) and opiate alkaloids in the opium poppy, Papaver somniferum (specifically morphine), which produces a dream-like waking state. This antagonism was known in folk medicine, discussed in eclectic (botanical) medicine formularies The antagonism between opiates and tropanes is the original basis of the Twilight Sleep that was provided to Queen Victoria to deaden pain as well as consciousness during childbirth, and which was later modified so that isolated alkaloids were used instead of plant materials. The belladonna herb was also notable for its unpredictable effects from toxicity.
