The bark is antipyretic, astringent and bitter.

Antipyretic: Treats fevers. See Febrifuge.

Astringent: Produces contraction in living tissue, reducing the flow of secretions and discharges of blood, mucus, diarrhoea etc.

Bitter: Increases the appetite and stimulates digestion by acting on the mucous membranes of the mouth. Also increases the flow of bile, stimulates repair of the gut wall lining and regulates the secretion of insulin and glucogen.

Other uses rating: High (4/5). Other Uses The heartwood is rose-red to orange or yellowish with some darker streaks; the sapwood a dull gray-white. The texture is fine, compact, but with a rough surface; the grain is straight to interlocked; lustre is bright; there is no distinct taste or odour. The wood is heavy, hard, uniform, with excellent mechanical properties and very durable if kept dry. It works well with hand and machine tools, though it has a moderate blunting effect; it finishes well. An excellent structural timber that is easy to split, it is used primarily in general construction for joinery, veneers, and in the construction of ship decks, flooring, furniture, truck bodies, sleepers etc.

How it is grown

Prefers a position with some shade. Prefers a deep, fertile soil. A slow-growing tree. Silvicultural trials have been carried out and in different sites tree heights at 12 - 13 years have ranged from 4.7 to 7.8 metres.

Propagating it: Seed - best sown as soon as it is ripe in a partially shaded position in a nursery seedbed or in individual containers. A germination rate in excess of 70% can be expected, with the seed sprouting within 10 - 20 days. Young plants grow away slowly. The seed can remain viable for at least 6 months in storage.

Best place to grow:

Habit: Tree

Hardiness: 10-12

Growth: Slow

Soil: Light (sandy), medium, heavy (clay)

Shade: Semi-shade, no shade

Things to keep in mind

The freshly cut wood and sap of Aspidosperma species causes irritation of the eyes, nose, and throat, with general malaise. The sawdust, on contact with abraded skin, produces local burning and a vesicular eruption with general symptoms of muscular weakness and cramps, sweating, dryness of the mouth, and faintness. Once the wood is thoroughly dry it loses its toxicity unless polishes or dyes in organic solvents are used on it
