I just see the stimpacks made from roots and flowers as the non-tribal way to make healing powder.
but you and Fleapants are right stupid is to strong of world. I know why they did it, Fleapants sums it up nice as to why. A mod to heal ED-E with weapons kits would be good.
I don't see it that way. In Fallout 2 Hakunin would mix Broc flower and Xander root to create a tribal "healing powder"; and the stuff drains 1 from perception for six hours.
Stimpaks were described as "
contains many healing chems. A soup of healing medication, if you will."; it can be assumed (though is not stated) that they are leftover (possibly military) medical supplies. There are no known (mentioned) major drug facilities manufacturing them. The idea that the PC can make one with a random syringe, flower and a root [to me], is just absurd.
