Curse of Strahd
Belladonna, also known as Deadly nightshade, or wolfsbane, is a plant that can be used as a potential cure for the disease of Lycanthropy. It does not actually cure the infection, but merely delay its effects for a period of time. In legend, the herb itself comes from the slavering mouth of Cerberus, the three-headed dog that guarded the gates of Hell. It grows in abundance in marshy or swampy areas and is quite toxic if not taken with medicinal care. One remedy for the toxic effects of this poisonous plant is a herbal remedy created with Meadow Saffron.
