I'd say you can extract soap fairly easily from Spicebush leaves. I've only used it to wash my hands while in the woods before, so this is new to me too. We have over two gallons of it to experiment with. It smells a little like a tea but you could easily fix that with essential oils or maybe with the fresh flowers from the bush. I'll test it to see how it does in the laundry and on hair. The color did not stain the pot, nor the spoon, nor our skin. We will discover if it will stain fabrics.
