Belladonna

Belladonna, or deadly nightshade, is a nightshade of shady ground that bears shining black berries. Healers use it to ease pain and spasm, but it is among the deadly plants, and its use is dangerous in unskilled hands. It is said that fine ladies have used it to brighten the eyes, which gave it a name that means fair lady. It is also said that it was used in Rome to poison great persons.
