In my area, spotted jewel weed (touch-me-not) commonly grows on stream banks and other wet areas. It has a translucent hollow stem that is juicy when crushed. I learned in scouts to use the juice to relieve the itching from stinging nettles, and I learned later that it also works on poison ivy rash. Since nettles and jewel weed are often found growing side by side, I have used this method often. It provides instant relief. Not only that, but when it blooms, the most amazing variety of hummingbirds, colorful butterflies and sphinx moths are attracted to the snapdragon-like flowers.
