Quebracho blanco wood is uniformly yellow-ochre, without differences between hardwood and sapwood. It is quite heavy (relative density = 0.885 g/cm³) and hard, and responds well to bending and shock. Upon drying it tends to collapse, producing deformations and cracks, so the drying process is slow; the wood must be treated with fungicides. It is easy to work and has many uses in carpentry (carts, wheels, floors, shoes, tool handles, furniture); it is also good for chess pieces, skis, etc. Preserved with creosote it can be used outdoors. In some places it is widely used as coal, since it does not produce sparks or large amounts of ash, and it burns strong and slowly.

Medicinal Uses:

Constituents: Contains six alkaloids: Aspidospermine, Aspidospermatine, Aspidosamine, Quebrachine, Hypoquebrachine and Quebrachamine. All agree that quebrachine is the most active.

Aspidosperma is used in medicine for the relief of various types of dyspnoea, especially in emphysema and in asthma. It is not generally useful to interrupt the paroxysm, but, as a rule, if used continuously, it will reduce the frequency and severity of attacks.

Under the name of amorphous aspidospermine, a mixture of the various alkaloids has become known in commerce.
