Dye plants: Natural resources from traditional botanical knowledge of Sardinia Island, Italy

Now a days the use of wild plant species for colouring textile articles is very modest in Europe, mainly because of the incessant production of synthetic dyes, which are economic and easy to find. The tradition of using dye plants still persists in the Mediterranean region, but is not widely studied. In this paper, the authors, for the first time, study the natural colours and wild species used in the popular Sardinian tradition. They try to bring order and Scientific rigor of an important topic, with an emphasis on the economic value of knowledge passed down orally from generation to generation.
