Toxicodendron sativa is a leafy plant native to northern Nagu. As a member of the Toxicodendron genus, its sap contains urushiol, an oily substance which causes painful rashes and blisters in most humans and dalar who come into contact with it. It has been cultivated by local astalvis throughout history for its leaves and berries.
T. sativa leaves are used as a leaf vegetable in foods like salads, wraps, and dips. They are soft with a mild lemony, slightly peppery flavor. The berries are usually around 1cm to 1.5cm in diameter when ripe, and can be eaten raw or cooked and included in jellies and spreads.
Humans and dalar should avoid foods which contain any part from the T. sativa plant, or which might have been cross-contaminated with T. sativa during preparation or manufacture, as consumption or contact with such foods may lead to rashes and blistering on tissues exposed to it. In Astalva and Goal, all such foods must be labelled as such before they can be sold to the public. The risk of surface contamination has led to its prohibition in various public-facing settings such as hotels, hospitals, and transit systems.
