The use of environmentally benign materials like medicinal plants leaf extract for the synthesis of silver nanoparticles offers numerous benefits of eco-friendliness and compatibility for pharmaceutical and other biomedical applications as they do not use toxic chemicals for the synthesis protocol. Green synthesis provides advancement over chemical and physical methods as it is cost-effective, environment friendly, easily scaled up for large scale synthesis and in this method, there is no need to use high pressure, energy, temperature and toxic chemicals. Silver nanoparticles have been demonstrated to show catalytic redox properties for dyes, benzene, carbon monoxide, and nitro compounds. On the other hand, heavy metals have a toxic effect that release to the water and contaminates food and have a harmful effect on the animals and human health. Ag NPs have been displaying faster rate kinetics in water treatment and also higher efficiency due to their high specific surface area and huge number of unsaturated atoms on their surfaces
