Edible usesThere are no edible uses listed for Rhus verniciflua.
The sap can be used as a varnish or a lacquer. It is obtained by incision of the stem, which is best done in mid-summer. The lacquer is frequently used in Japanese art, it requires a damp atmosphere in which to dry and harden, a moist cave being ideal. It is resistant to acids, alkalis, alcohol and temperatures up to 70°c.The leaves and galls formed as a result of insect damage are rich in tannin. The leaves can be collected as they fall in the autumn and used as a brown dye or as a mordant.
The leaves are used in the treatment of wasting diseases and internal parasites. The seed is haemostatic and is used in the treatment of dysentery. A resin from the plant is emmenagogue, haemolytic, stimulant, tonic and vermifuge.Some caution is advised in the use of the leaves and stems of this plant, see the notes above on toxicity.

One report says that this species is only hardy into zone 9 (tolerating only occasional light frosts) but there are large healthy trees at Cambridge and Edinburgh Botanical gardens, and both sites had fruiting trees in September 1989[K]. Plants have brittle branches and these can be broken off in strong winds. Plants are also susceptible to coral spot fungus. Plants in this genus are notably resistant to honey fungus. Cultivated for its lacquer in the warmer areas of Japan. Many of the species in this genus, including this one, are highly toxic and can also cause severe irritation to the skin of some people, whilst other species are not poisonous. It is relatively simple to distinguish which is which, the poisonous species have axillary panicles and smooth fruits whilst non-poisonous species have compound terminal panicles and fruits covered with acid crimson hairs. The toxic species are sometimes separated into their own genus, Toxicodendron, by some botanists.Partly dioecious. Male and female plants must be grown if seed is required.
