I've always been fascinated by the idea of healing injuries and treating poison and sickness with herbs, and I think it'd be an interesting roleplay to become a doctor who specializes in using things from the Irradiated Wilderness of the Capital Wasteland for treating the injuries and radiation sickness of his or her patients. What do you guys think of this idea?
Also I suppose some Wasteland Animals can produce substances that would be useful as substutes for chems like how Fire Ants produce a nectar that helps protect against burns and Nukalurk's tissue can heal a lot of health while at the same time giving a boost of energy.
