Often called the "touch me not" impatient it is botanically known as Impatiens Capensis, and is commonly known as Jewel Weed. Jewel weed produces near water or in shallow ponds. It's been said that jewel weed grows wherever Poison Ivy is found, but that isn't really true. Poison ivy can grow well under most any conditions, sunny or shady. But jewel weed is a shade loving plant, one that prefers valleys with rich soil and moist bottom lands. It may sprout in a sunny area, but it will not survive for long in the light.
There are many ways to use jewel weed, but drying it is not practical because it has a very high moisture content. For this reason, the soaps, salves and sprays made from this herb are made from either the fresh or from frozen jewel weed.
One of the easiest ways to benefit from this flower is simply to take the stem and slice it, then slather the juice onto the skin that has come into contact with poison ivy. If you get it applied before the rash appears, it will generally prevent any from developing. If you already have a rash, it will help to ease the irritation. In fact, many people use the stem juice as a preventative treatment for poison ivy reactions, and it seems to work well.
When foraging, make sure that you are looking for the orange flowering jewel weed though, not the yellow. The yellow is less concentrated, and will probably not offer you the relief you are looking for. A fresh plant will last about a week in a sealed container when placed in the refrigerator, or you can make an infusion and freeze it for later use.
To make an infusion, boil the leaves of the plant. Brew the chopped jewel weed leaves in boiling water, until you get a dark orange liquid in your pot. Then strain the liquid, and pour it into ice cube trays. Then, when you have a skin rash, just grab out a cube and rub the affected area with your "jewel cube". It will keep in the freezer for up to one year, or you can preserve the infusion by canning it (in a pressure cooker).
If you want to make soap with the jewel weed, either make an infusion to incorporate as your liquid, or
Whatever you do, do NOT make alcoholic tinctures from Jewel weed. Some people have had very bad reactions when mixing and using jewel weed with alcohol.
