A Delicate Situation: Blindweed

Calling all Heroes! We have recently had our alchemists doing some unsanctioned chemical weapons research.. To sum it up, we were trying to make a poison bomb. In hindsight, maybe we shouldn't have diverted all of our resources to such a ridiculous project, but hindsight is 20/20, right? Anyways, all of our herbalists are... indisposed at the moment.. Due to some mysterious and completely unrelated mass poisoning. We still have deadlines to meet. Our alchemists require 5 Blindweeds. Naturally, you will be handsomely rewarded for your assistance, hero.
