Other Uses

The reddish-brown wood is not very hard, very strong, fairly light, durable and easy to split. It has splendid markings and is used for furniture, building material for houses, canoes, fancy articles and inlay work. A resinous exudate from the wood can cause severe skin irritation. The poisonous constituent of the resinous sap is volatile and will gradually disappear. For this reason, the timber of this tree must be dried and exposed for several years as it is otherwise dangerous to handle. Lacquered articles or furniture made from the dried timber may still be toxic to persons who are especially susceptible.
