“Woody nightshade is also known as bittersweet nightshade, dulcamara, felonwood, and felonwort. In the Middle Ages the name dulcamara was written more properly as Amaradulcis, and literally means "bittersweet". Felonwood and felonwort are not as sinister as they sound; felon is not referring to criminals, but rather to whitlow, which is inflammation of the toe or finger around the nail. The berries were used to sure this problem when other methods had failed. The plant was used for many medical conditions, including dissolving blood clots (in bruises), for rheumatism, fever, and as a restorative. Farmers used it as a charm around the necks of animals they thought to be under an evil eye. Bittersweet berries are red rather than black like deadly nightshade.”
