Reagent Producing Pathogens [New Path Symptom]

[Eibel]

I love this one from a medical standpoint, both positive and negative. If it ever becomes a "most chems can show up" situation, it would be entertaining to see in action.

Penetic acid, omnizine, charcoal are good positive examples
Calomel would be annoying as hell to get (due to health damage and never being able to use stimulants for their full duration)
Styptic, silver sulf are negative examples (due to toxin damage on injest)
