Like Jona690h said two years ago Jarrin Root on it's own will do two hundred points of damage enough to kill your regular npc, and player unless they picked to increase health over ten times while leveling (or use enchantments).

If made into a potion it does get a bit ridiculous and can do thousands of points of damage without using any exploits.
