Ailanthus integrifolia is not used in traditional medicine, despite the active compounds revealed by phytochemical research. The wood is traded as timber, and also used for local house building and furniture manufacture.

A large tree up to 60 m tall, bark surface smooth or irregularly fissured; leaves paripinnate with 2—9 pairs of entire leaflets 10—40 cm long, lower surface sometimes pubescent and with a few large black glands; petals puberulous, carpels 5, puberulous; samara 11—22 cm long. Ailanthus integrifolia is divided into two subspecies: subsp. integrifolia and subsp. calycina (Pierre) Noot. The former has up to 15 mm long pedicels and 6—10 mm long petals and occurs in primary rain forest up to 900 m altitude throughout Malesia, except for Java and the Lesser Sunda Islands, and on the Bismarck Archipelago and the Solomon Islands. The latter has pedicels up to 5 mm long and petals about 4 mm long and occurs in mixed seasonal primary forest in western India, southern Vietnam and Java. Ailanthus integrifolia is potentially of medicinal interest.
