Abstract In recent decades, the increasing number of degraded lands worldwide makes their rehabilitation essential and crucial. Various techniques have emerged to fulfill these needs but most of them are expensive and difficult to be applied. Revegetation is a cost effective, environmental friendly, and aesthetically pleasing approach suitable for degraded areas. However, the use of edible crops, especially for areas with heavy metals (HM) contamination, is not ecologically suitable because the HM may enter the food chain. Alternatively, non-edible, fast-growing, deep-rooting, and metal-stabilizing plants with high biomass, which can produce high-value products hold a great potential and have been regarded as potential candidates of edible crops. This current review presents the benefits of using aromatic and medicinal plants (AMPs) and their associated microorganisms for revegetation of degraded sites as they are high-value economic crops. We discussed the effect of various stress on productivity of secondary metabolites in AMPs in addition to the potential health risk with human consumption of these plants and their products. A focus was also given to the effect of HM stress on the essential oil (EO) content of certain AMPs. Reported data showed that AMPs growing on HM-contaminated soils are safe products to use as they are not significantly contaminated themselves by HM. Keywords Degraded land . Revegetation .

Introduction Human activities and industrial heritage have caused very acute environmental problems especially soil degradation that, over the years, became a widespread problem around the world. The massive degradation of soil quality can affect its ability to perform its essential functions within the ecosystem (Citeau et al. 2008). This problem is particularly more pronounced in arid and semi-arid environments, where the Responsible Editor: Elena Maestri * Ali Boularbah [email protected]; [email protected] * Abdelaziz Yasri [email protected] 1

pedoclimatic conditions naturally contribute to land degradation and have increased significantly with economic and industrial growth. It was estimated by Jones and Rowe (Jones and Rowe 2017) that the overall picture of degraded lands is between 1.2 and 1.9 billion ha. Unfortunately, because of the difficulties in defining land degradation and the lack of appropriate i
