Yeah, that one was a trip on my own side. The 4th ed book just sat it out there and went "Done!" and let us hanging. I was eyeballing the deadline and trying to figure out what to do when the massive chamical chapter was finished and I went, "Okay, phew, we can roll with that." ... But about everything there is also synthetic, so doesn't work. D'oh!
So, yes, at some point, we'll need to make a nice long list of natural chemicals and their effects, from tree frog poison and cobra venom to insulin overdoses and low-grade adrenaline boosts.
Well, nobody ever said this job'd be *easy*.
