I can't say I have a ton of formal training, so if you want to show me how you do things, I'm willing to learn. I was an auror, it's kind of like-I think you called them police officers? So I got some training in the basics and a lot about stabilizing someone until we could get them to hospital. And I was...during school we had to deal with a lot, so I learned some as I went then too.
As for plants, I have a greenhouse and a few gardens in the bio-dome. I have a few already that can be used for pain relief, as diuretics, laxatives or to induce vomiting, some that have some sedative properties, and then a few more that can be used in potions as well. I also got some seeds at Christmas through the door, once they're mature I'll be able to do more. If you want to meet me there sometime I can walk you through everything. You wouldn't be able to make the potions but a lot of them can be used just by having someone eat a certain portion of the plant or applying a paste to a wound.
I'm not sure honestly, the only training I've done used magic to simulate injuries and then we used magic to fix them, but I don't know what spells they used to simulate the injuries. I could try your mannequins? Magic at home didn't work well with electronics but it doesn't seem to be much of a problem here.
