Heavy Metals, Micronutrients, and Medicinal Properties of Ricinus communis and Glycyrrhiza glabra

Heavy metals are located in nature, derived from both natural and human-made sources as they accumulate in soil, flora, and fauna. Some metals like iron, zinc, and copper are essential as micronutrients for both plants and animals, while others such as cadmium, mercury, and arsenic are dreadful for one’s health. The absorption of heavy metals by plants is dependent on the soil composition and plant variety, resulting in an increase in the food chain and the risk of having toxicity. \n\nMicronutrients are responsible for the metabolism of the plant, and if absent, results in stunted growth, chlorosis, and decreased productivity. However, the surplus of them can contribute to toxicity which could disturb the normal cellular process and cause oxidative stress. The balance between the levels of micronutrient supply and the respective toxicity caused is managed through homeostasis, which when dysfunctional can harm the health of the plant and its productivity. \n\nThese two plants, Ricinus communis and Glycyrrhiza glabra are well-known as two medicinal plants for their pharmacological uses. For instance, Ricinus communis can be used in traditional medicine because it has bioactive ingredients that possess antimicrobial, anticancer, antidiabetic, and anti-inflammatory purposes which makes it truly remarkable.
