My notes from the lesson on poisons with Devina:

(Note, some may not be able to replicate these items)

Poisons
1) Bitter root causes numbness of tongue and gums when chewed. When applied to lacerations, or other small wounds, it numbs the surrounding area. Better when applied in a paste.
2) Crimson blossom root: Causes bleeding when chewed, when boiled with bitter root, causes unstoppable bleeding. About a foot into the ground, nodules should be present. Cut them off and be cautious not to touch your mouth or open wounds before washing hands. Store separately in a leather pouch.
3)Plains weed; is sweet. It, when mixed with these other two ingredients, causes a euphoric response in the victim. Animals do not respond to any attack when using this poison first. Alone it is harmless, just simply sweet like wild berry. No adverse effects from trying a bit of the stalk. The off putting taste is why Bos won't eat it. The Plains Trolls seem to like it, though.

To cure:
The use of a Holy Ring will, obviously, stop all bleeding. The issue with this poison is that, unless you see the blood pouring out, you may not know you are poisoned.

Extra information concerning Illness in general:
The Dark Sickness: It is a common illness associated with the Dark Tendrils and the Darkness.
The effects on the victim: excruciating pain. It passes after three marcs, but few can stand the pain. There is no cure for the Dark sickness, save but time.

Conclusion to poisons is: Unless there is some outward symptom, the victim may not know they are poisoned. They may attribute it to a stomach ache, or merely a cold.

(This was our first lesson. I've removed some of her extra notes, rewritten them elsewhere, and changed words used. Beyond that, the only other thing changed is the removal of personal information. A side note, no poison of mine has touched a fellow adventurer. As for the Six, what is written is written.)
