Solanum dulcamara, also known as climbing nightshade, bittersweet nightshade, blue bindweed, Amara Dulcis, felonwood, poisonberry, scarlet berry, snakeberry,… is a species of vine in the potato genus Solanum, family Solanaceae. It is native to Europe and Asia, and widely naturalised elsewhere, including North America, where it is an invasive problem weed.
Solanum dulcamara has been valued by herbalists since ancient Greek times. In the Middle Ages the plant was thought to be effective against witchcraft, and was sometimes hung around the neck of cattle to protect them from the “evil eye”.
John Gerard’s Herball (1597) states that “the juice is good for those that have fallen from high places, and have been thereby bruised or beaten, for it is thought to dissolve blood congealed or cluttered anywhere in the intrals and to heale the hurt places.”
