Toxicodendron is a genus of flowering plants in the sumac family, Anacardiaceae. It contains trees, shrubs and woody vines, including poison ivy, poison oak, and the lacquer tree. All members of the genus produce the skin-irritating oil urushiol, which can cause a severe allergic reaction. The generic name is derived from the Greek words τοξικός (toxikos), meaning "poison," and δένδρον (dendron), meaning "tree". The best known members of the genus in North America are poison ivy (T. radicans), practically ubiquitous throughout most of eastern North America, and western poison oak, similarly ubiquitous throughout much of the western part of the continent.

Jimbu is a herb belonging to the onion family, used extensively in some regions of Nepal and in some central Himalayan states of India, like Uttarakhand, where it is called Jamboo or Faran. It is composed of two species of Allium, A. hypsistum and A. przewalskianum. The herb, which has a taste in between onion and chives, is most commonly used dried.
