Natural Indigo Production in El Salvador

SAN MIGUEL, EL SALVADOR - NOVEMBER 12: Miguel Ventura from El Salvador, natural indigo producer, pours liquid indigo solution onto a cloth sheet to filter out the water at the semi-industrial manufacture near San Miguel, El Salvador on November 12, 2016. For centuries the indigo, a natural deep blue dye extracted from the leaves of tropical plants (Indigofera), has been known by the native indigenous of Central America who used the blue tincture to color their fabrics and pottery. Small-scale indigo farms, that process the crop on a sustainable and ecological basis, are growing throughout the country. (Photo by Jan Sochor/Getty Images)
