Since the most ancient times, our civilization developed dyeing’s techniques using the herbaceous species’ type that grows in the area. In the European area, they employed reseda for yellow dye, rubia for red dye and woad for blue dye: these were the plants they used to extract the three main colours to dye fabrics until XIX century. A multitude of other officinal essences were employed to dye clothes, like smoke tree, saffron crocus, broom, safflower and nettle.
