Idea for poison?

[Hubris]

I have an idea for a poison which may end up being useful for a plot in a story which I am running for a few friends...

How would you, the prospective reader, introduce a poison which makes it harder for a person to stabilize when unconscious and bleeding? A poison which basically makes it harder to clot blood? Anemia-on-a-stick?

Would straight constitution damage cover this effectively, or would that have additional effects? I want a cheaper poison which does just that one trick, and a cursory glance at my core rulebook hasn't provided me with rules for how to make a new poison. Perhaps I will just houserule it for this, but I want to make it an option for players in the future. (we keep a list of houserules that have been added, including feats/abilities/spells. Adding a poisoning section to it would be nice.)

Hahaha tasty? I wonder what you would have to put into food to make it do that... It probably needs more salt though, whatever it is.

Maybe rat poison, that sounds like what you're describing. As how to introduce it, well...
1) make them loose all rations
2) Only offer rats to eat
3) Have rats be poisoned

Warfarin? If you take damage, you keep bleeding... Hmmm, having such a poison would translate into having every wound start bleeding as normal, 1 hp/round, and not stopping without magical healing. Or even with magical healing. It would be a rather weak poison against a PC with a few levels, but against others it would be absolutely murderous. You need healing on hand to survive it.

Warfarin it is, then. Thanks. Perhaps for the purposes of this particular scenario, I'll water even that down a bit. They are second level, and only one of the players has been in a game before. The paladin in particular is who I am trying to help out this time, so that he can understand the mechanics of his class better.
