Description
The Tara tanning agent is extracted from the fruit husks of the small Tara tree (Cesalpina spinosa). The plants grow in Peru in the mild climate of the valleys of the Andes. The plants grow predominantly as wild plants. To a small extent they are cultivated by the native farmers as a protection against erosion or as a natural boundary of their areas under cultivation. In April the Tara husks are harvested. During the harvest the trees are not damaged. The sales of these husks are an important source of income for the rural population in Peru. The precious content of the yellow-red Tara husks were already used centuries ago by the population in Peru as a remedy against sore throat. Various other fields of application of the husks and their content are known: as a basic raw material for the production of colours, as reduction agent in the chemical industry or as decantation agent in the production of alcoholics.

Application
The Tara tanning agent produces cream coloured leather, which is easy to dye and possesses a high light fastness. Tara leathers are available in soft and firm versions. They can be used for car upholstery leather, shoe leather, furniture upholstery leather or leather clothing.
