Belladonna

Belladonna, also known as wolfsbane or deadly nightshade, was a type of poisonous herb found in the Realms that was related to horseradish.

Description
Being a type of flowering plant, belladonnas produced delicate purple flowers.

Abilities
Belladonna were most famous for their ability to cure lycanthropy. However, they were also toxic - anyone eating them was likely to find themselves weakened physically. Consumption of their flowers was capable of inducing state of death-like sleep. Some claimed even the plant's touch was toxic and required protective gloves to harvest.

Habitats
Belladonna was known to grow in parts of the High Forest, in Bloodbark Grove in the High Moor, as well as on the small Isle of Balduran, in the Trackless Sea

Beyond the Prime Material plane, belladonna could be found in both the Feywild and parts of the Domains of Dread.

Uses
If a victim bitten by a lycanthrope ate a sprig of belladonna within an hour of the bite, they had a chance of not contracting the disease. The belladonna, however, had to be relatively fresh, not picked any later than a week ago.

Though consumption of belladonna worked equally as well for giants and giant-kin infected with lycanthropy, they needed to consume much larger amounts than the smaller humanoid races.

Belladonna was used as a material component for a variety of charms, potions, spells, and obscure necromantic rituals. Because of this they were frequently harvested by hags and witches. One spell known to require belladonna was protection from poison. It was also used in gas bombs invented by the lycanthrope-hunting organization known as the Silver Stake.
