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.
Part Used: The Bark.
Constituents: Contains six alkaloids: Aspidospermine, Aspidospermatine, Aspidosamine, Quebrachine, Hypoquebrachine and Quebrachamine. All agree that quebrachine is the most active.
Two new sugars, quebrachite and laevogyrate inosite, tannin and starch have also been extracted.
Used as Tonic, febrifuge and anti-asthmatic.
Antispasmodic. Treats asthma and emphysema. Tonic. Reduces fever. Astringent – it has been used on burns and cuts. Contains yohimbine.
When a preparation of Quebracho or Aspidosperma is injected into the circulation, the rate and depth of the respiration increases largely, apparently due to direct action on the respiratory centre, and the blood-pressure falls.
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.
Other Uses:Wood is very hard and is used for various purposes.
