Toxicodendron succedaneum, the wax tree, Japanese Hazenoki tree (Sumac or wax tree), sơn in Vietnamese or charão in Portuguese, is a flowering plant species in the genus Toxicodendron found in Asia, although it has been planted elsewhere, most notably Australia and New Zealand. It is a large shrub or tree, up to 8 m tall, somewhat similar to a sumac tree. Because of its beautiful autumn foliage, it has been planted outside Asia as an ornamental plant, often by gardeners who were apparently unaware of the dangers of allergic reactions. It is now officially classified as a noxious weed in Australia and New Zealand. It is one of the city tree symbols of Kurume, Fukuoka, Japan.
The larvae of the moths Eteoryctis deversa, Caloptilia aurifasciata, Caloptilia protiella, Caloptilia rhois, and Callidrepana patrana feed on T. succedaneum.
Safety
The plant produces hinokiflavone, a cytotoxic biflavonoid. Its stems are also a commercial source of fisetin, extracted in China.
Uses
It is used to produce lacquer. In Vietnam, lacquer is used to produce lacquer paintings, known as sơn mài, from resin of the tree.
