Cannot use any other type of blood (Ogre or Troll). The 5:1 ratio of weeds to wild grass works most of the time (currently prof 5)

I decided to try the ogre and troll blood, because that's all I had. Every few elixirs it would tell me it failed, but when I forced it, I still got concentration elixirs with the troll and ogre blood. So, if you're patient(more like stubborn) you can use them. Sitting at Skilled 8 on this character.
