Natural dyes such as indigo, pomegranate rind, myrobalan, lac and manjistha as well as benign chemicals like aluminium and iron are eco-friendly alternatives to the synthetic dyes and hazardous chemicals used in conventional fabric dyeing. Natural dyes are made from plants, earth clays and even insects, which translates to less harm to the ecosystem. Another eco-friendly alternative is the use of vegetable dyes on leather garments.
