Poison Ivy Cream. Jewelweed is the wild form of impatiens (yes, the same kind that you plant in your flower beds in the spring), and it's the plant for poison ivy, poison oak, and poison sumac relief. Corticosteroids are available as oral tablets, topical preparations (creams/ointments) or injections.
About Poison Ivy: The plant Poison Ivy contains urushiol which causes allergic contact dermatitis in people sensitive to urushiol. It must be reapplied every four hours and it leaves a clay residue on the skin. Take oral antihistamines, such as diphenhydramine (Benadryl, others), which may also help you sleep better.
Effective relief from skin itching, pain and discomfort due to insect bites/stings, poison ivy/oak, poison sumac or minor skin irritations.
Poison sumac has paired, pointed leaves, sometimes.
The severity of the rash depends on the amount of urushiol contacting the skin and the sensitivity of the individual. A doctor may suggest a topical corticosteroid cream, but other over-the-counter options may cause allergic reactions. Frequently, the rash takes a linear form (as in the top-left corner of the photo) due to the way the plant sweeps across the skin.
