"Usefull for some potions, including Doxycide."
Hemlock is the common name of Conium maculatum, a perennial herbaceous flowering plant widely known for being highly poisonous.[1]

It can be used as a potion ingredient, and a "good glug" of hemlock essence was an ingredient in Zygmunt Budge's recipe for Doxycide.[2]
