"

In East Asia, in particular in Japan, traditional candle fuel was produced from Toxicodendron vernicifluum and Toxicodendron succedaneum, among other sumac plants in the genus Toxicodendron, rather than beeswax or animal fats. The sumac wax was a byproduct of traditional Japanese lacquer manufacture. The conical rousoku candles produced from sumac wax burn with smokeless flame and were favored in many respects over candles made from lard or beeswax during the Tokugawa shogunate. Japan wax is not a true wax but a solid fat that contains 10-15% palmitin, stearin, and olein with about 1% japanic acid (1,21-heneicosanedioic acid). It is still used in many tropical and subtropical countries in the production of wax match sticks.[citation needed]
