In the last years, we have noticed that the air is becoming harder to breathe, the soil lost its capacity of production, while water changed its colour and smell. This is a major consequence of environmental pollution of air, water and soil, with various contaminants that have an immediate or long-term effect. Heavy metals are among the most researched pollutants, due to their persistent nature in the environment, high abundance and non-biodegradable. Regarding the effects to human health, heavy metals can cause mutagenic effects, endocrine disruption and neurological disorders even in low concentrations. For an efficient, eco-friendly and low-cost removal of heavy metals, phytoremediation seems to be one of the most suitable and promising technologies. The goal of this paper is to analyze the opportunities of using medicinal plants to remove heavy metals from the environment. Nowadays, even if medicinal plants have multiple uses, they firstly remain known for their use in traditional medicine, in industries such as food, pharmaceuticals, essential oils, cosmetics and even ornaments. Also, they play an important role for the environmental counterbalances to industrial and agriculture pollution. Studies showed that medicinal plants have different abilities in phytoremediation such as: 1) to remove, uptake or inactivate harmful environmental contaminants such as Cd, Ni, Pb, Cr; 2) to absorb elements from soil and water; etc. The distribution of heavy metals on plants could be influenced by the anatomic and biologic peculiarities of the plants. It was identified that Ocimum basilicum was able to accumulate significant amounts of Cd, Pb and Zn in their roots, while Lavandula spica was able to uptake significant amounts of the same metals in their leaves. On the other side, it was observed that Lavandula angustifolia tended to accumulate metals mainly in its roots and stems. There are different hypothesis regarding the accumulation in leaves. An explanation could be the dispersion into the air by aerosols of heavy metals that fall onto the leaves. Another one could be that the uptake of heavy metals is mainly done by roots followed by the movement of the heavy metals through the conductive system to leaves. After long research, regarding the accumulation of heavy metals in medicinal plant, the result showed that it varies depending on the plant species and metal elements. Due to adaptation mechanisms of medicinal plants, they show a good capacity to survive under a highly polluted environment.
