According to this study: The effectiveness of jewelweed, Impatiens capensis, the related cultivar I. balsamina and the component, lawsone in preventing post poison ivy exposure contact dermatitis - ScienceDirect
jewelweed mash was effective on poison ivy, but extracts that they tested were not. And they say that soap is more effective for preventing a reaction after exposure. Which makes sense- any urushiol you get rid of won't be there to cause a reaction. Of course you could do that and use a jewelweed mash on any rash that happens anyhow.
Unfortunately jewelweed does not grow in the west.
