I got some jewel-weed over the weekend and was able to make a pretty concentrated liquid form of it. Has anyone ever tried to make soap using it? It is great for Poison Ivy. I still have the dried leaves and things too, so I dint know if anyone had any suggestions. I was thinking just using it instead of the water…you think that would work?

I've found no difference in effectiveness between Jewelweed soap and any other good soap that's not excessively superfatted (the main point is to scrub away all the plant oils and dry out the rash), and I suspect the lye & heat damage the good stuff in the Jewelweed juice.  What I have found very effective and soothing is applying the juice or macerated jewelweed directly to the exposed area or rash.  To prepare and preserve my therapeutic stash of jewelweed, I lightly chop plant bits and toss them in the blender with enough water to make a slurry – no need to blend until smooth, just until it'll pour into ice cube trays.  Once frozen, I pop the cubes into a ziplock bag and store until needed.  No need to thaw before use.  Just scrub the exposed area/rash with good soap, then rub the jewelweed ice cube over the area and let the juice and weed bits dry on your skin.  It's kind of messy, but so soothing.

You can add it as a tea or in superfatting oils — either way will make very nice, interesting soap.  I've seen it done both ways and tried it both ways but I never sold jewelweed soap because I thought it wasn't the best or most effective use of what for me was a fairly rare commodity.  (Never was blessed with a huge, out-of-control patch, just a small, carefully tended patch that was sustainable if not overharvested.)
