Lots of mmrb trees on my property is any one interested in the rootbark for the soap you make

Hey I have a bunch of mimosa trees on my property we'll dig them up for the root bark if worth my time

Not sure about soap, I know it is used in Native American dyes. Goes for $325/kg of powdered bark online. If you know how to clean and refine it a bit maybe worth the time? Wouldn't be worth mine unless I was going to make some dye for myself.
