Winter recommended the use of herbicides for removing the plants. More than one application may be required to ensure thorough removal. Use caution when removing dead plants after spraying with herbicides. The primary concern is for secondary infections resulting from the blisters. If exposure or the possibility of exposure occurs, avoid touching sensitive parts of the body with unwashed hands.
Eyelids are especially sensitive.
The least susceptible areas are the palms, scalp and the soles of the feet. Use caution in seasons other than summer when the plants may not be easy to distinguish. Because of its bright colorful leaves, many people mistakingly cut the plant for ornamental reasons in the fall. In the winter, when no leaves are present, reactions may be caused by breaking roots or plant stems. Consult with a physician whenever the rash covers more than 5 percent of the body or if infection is occurring, said Linda Patterson, extension health specialist at Mississippi State University.
