A Natural Remedy For Poison Ivy - Jewelweed

Down by the water’s edge in August and September, there’s a wild flower that shouts for us to notice her glowing, sunny disposition. She is two to five-feet tall. Her trumpet-shaped flowers are orange and freckled, with a curl to the tail. Her leaves appear scalloped and her stem is succulent. If you hold one of the leaves under water, it will have a silver sheen.
Might you recognize this helpful plant?

More background forthwith: she is from the genus Impatiens and the Balsaminaceae or Touch-me-not family. This summer, I have spotted this lovely wildflower in abundance on Cape Cod (especially at the unique Stony Brook Herring Run in Brewster, MA) and at picture postcard views, New Found Lake, New Hampshire. The final clue…this plant has been used by first peoples as a remedy for poison ivy for over 250 years. There does exist a natural, organic remedy for poison ivy!!
Her name is Jewelweed (Impatiens capensis).

What exactly is Poison Ivy?
Rhus toxicodendron or Rhus radicans are the botanical names for this three-leafed member of the Cashew family. Appearing in several guises, poison ivy can be a low shrub, or a trailing or climbing vine. To most, a brush-by meeting with this native is always memorable and always unpleasant.

Poison Ivy Rash
Poison ivy rash is an allergic, contact dermatitis caused by a substance called urushiol (you-ROO-shee-ol), found in the sap of poison ivy, poison oak and poison sumac. Urushiol is colorless or slightly yellow oil that oozes from any cut or crushed part of the plant, including the stem and the leaves. This oil can be carried on the fur of animals, clothing, on garden tools, or sports equipment. Once it touches the skin, a reaction may be seen in sensitive folks, within 12 - 48 hours in the form of a line or streak of rash. The affected area will display redness and swelling followed by blisters and severe itching.

 Prevention and First Aid
The first line of defense is to avoid contact with PI. This means long sleeves, pants, socks and closed shoes for: gardening, hiking, picnicking, jogging, and camping. Dr. Edward Frankel, a poison ivy expert, recommends early treatment with lots of plain, cold, running water.
1. Jump in the lake, jump in the ocean, jump in a cool shower or use a garden hose. “The sooner and longer you shower, the better are your chances of avoiding or minimizing a rash.” Soap is not recommended and neither is warm water as these quicken the absorption of urushiol.
2. Do not scratch! Scratching the skin invites secondary infection. Cut your fingernails short.
3. Jewelweed can help. Here’s how:

Jewelweed Ice Cubes
(Impatiens capensis)

Search damp, shady soils for the juicy stemmed jewelweed plant. Remember, this green friend prefers ‘wet feet’ as does poison ivy. A good resource for drawings and pictures of Jewelweed is Peterson’s Guide to Medicinal Plants by Foster and Duke. I know that you can also find photographs on the Web.

Collect at least one-half a gallon’s quantity of the plant, stems, leaves, and flowers. Chop into pot-size pieces and toss into a non-reactive pot as Pyrex or enamel. Cover with water, and the pot lid and ‘simmer’ until the water is reduced by one-half and has turned an amber color. Cool. Strain out the wilted herbs and place these in a plastic container with a lid. Refrigerate up to one week.

If you have been exposed to PI, rinse the affected area well and place the wilted herb directly on the area. Create a compress by covering with muslin or cheesecloth for at least 20 minutes.

Step two: Strain the Jewelweed liquid and pour into plastic ice cube trays. Label the trays, ‘Jewelweed’.
When frozen, transfer the ice cubes to Ziploc freezer bags. If anyone has been in contact with poison ivy, a cool wash with the frozen cubes usually does the trick.
