Belladonna

I don't think you will turn into a rat, we can take care of this... said Beranhond, answering Nym's questions. She nodded, excited, as he explained who the others were. At the mention that the gnome was in fact a bard, Nym smiled widely, excited at the thought of hearing a bard play. She squirmed more, distracted by the possibility of a musical treat. Beranhond finished cleaning and dressing her wound. While he finished, he pulled out a small bag that smelled of herbs. He said, handing it to her, Just to be sure, you should eat this - we wouldn't want you turning into a wererat after all. Nym took the pouch dantily and turned it over in her hands. Probably Belladona... well, I guess I'd rather be retching than turning into a rat... She opened the pouch and smelled the herb. Knoweldge arcana for the Belladona: (1d20)+4, 17+4,21

As she held the open pouch she breathed deeply and thought of her father and her home...

Nym was 8 years old. A woman had practically burst in to their home, babbling about lycanthropy and having had to travel many miles to find an herbalist to help her. She was slight and blonde, a plain human to be sure. She and her small son had ridden all the way from Loudwater, where a band of werewolves had been terrorizing the farmland for several months. Her son had been bitten about 40 minutes prior. Nym peeked into the entry where her father was urgently talking with the woman. The boy's arm was mangled and bloody. He escorted the women into the house and had her sit, applying an ointment to the boy's arm.

Nym, come with me. Her father said, as he rushed toward the door. They hurried into the night. It was windy and cool in the dark forest, and Nym was struggling to keep up with her father as he silently moved threw the undergrowth. Her father scanned the dark underbrush for herbs. Little princess, I need you to find a closer source of Belladona than our normal plant. It is too far away to help that boy... Nym nodded, and sprinted off into the undergrowth. She new the plant grew near a cave she often played in and she ran to collect it. She wondered if they would get the herb to the boy in time...

..Nym shook her head, coming back from her memories, and realized she'd been staring at the Belladona in the pouch for some time. She smiled awkwardly at Beranhond, chuckled half-heartedly, and ate the herb. Belladona. A mild poison. Used for stopping the spread of lycanthropic infection in the system and can be used as a sedative. It's also known as the deadly nightshade. In high does, it can kill. Nym said matter-0f-factly as she chewed and swallowed the herb. She knew in about 10 minutes she would likely be ill. Take it away, Dan, how vomity am I from failing my poison save?
