The following plants are often implicated:

  * Rhus (//Toxicodendron succedanum//)
  * Poison ivy (//Toxicodendron radicans//)
  * Mango
  * Cashew tree

The major complications are secondary infection and subsequent nephritis.

Treatment comprises local & systemic steroids and symptomatic treatment with [[:wikitox:2.1.11.4.2_antihistamines|antihistamines]] and bathing, calamine lotion etc.
