A small tree native to China but cultivated in other countries with subtropical climates. The kernels yield a valuable drying oil, mainly used in paint and varnish. The foliage and the oilcake are unpalatable and poisonous. As the toxic elements have not been specifically identified, no detoxification process has been developed. However, tung meal has been detoxified experimentally by percolating it in ethyl alcohol for forty-eight hours, after which it is moistened and finally steamed for two hours. Supplemented with lysine, it produced good growth in chickens. The detoxified meal as unpalatable to pigs, and a maximum of 20% tung meal can be included in rations. Untreated meal is toxic and used only as fertilizer.
