ABSTRACT
Heavy metals (HMs) and organic pollutant poisoning of soil as well as water have become a global environmental health issue that has created a lot of attention. Because HMs accumulate in the food chain, it poses a serious threat to health of human and other organisms. Phytoremediation is an emerging technology as a safer, less expensive, and environmentally sustainable approach than traditional physicochemical decontamination procedures to address this pressing issue. Phytoremediation, or the usage of green plants to eliminate, contain, or reduce harmful environmental contaminants is harmless, eco-friendly, and inexpensive remediation strategy. Medicinal plants may be used to effectively remediate the contaminated sites. It uses a variety of mechanisms to reduce, eliminate, or immobilize pollutants, including phytodegradation, accumulation, dissipation, and immobilization (hydraulic regulator). We have covered the HMs’ effects on medicinal plants, and the phytoremediation potential of medicinal plants for HMs-mediated contaminations in this chapter. Aside from its advantages in the remediation of HMs containing zones, an understanding of the mechanistic component of phytoremediation potential of particular medicinal plants for a sustainable strategy has been recorded.
