Surprising benefits of silicon in plants and human beings

Abstract

Silicon is the second most abundant element on Earth and the third most abundant trace element in human body. It is present in water, plant and animal sources. Silicon is known as a beautifying mineral and there are many health benefits associated with it. It is a macro element involved in the responses of plants to a variety of abiotic stresses. The culture medium composition, particularly the mineral nutrients, greatly impacts the growth as well as the morphogenesis of in vitro plant cultures. Silicon not only helps strengthen connective tissues and bones but is also useful in skin, nail, and hair care. They also play a vital role in the prevention of atherosclerosis, insomnia, tuberculosis, and aluminum toxicity. Silicon and silicic acid may decrease the bioavailability of aluminum by blocking the uptake of the latter by the gastrointestinal tract and impeding its reabsorption in the kidneys. Silicon has also been suggested to be involved in mammalian hormonal control, and protect people from heart diseases, anticancer, anti- atherosclerotic, and anti-diabetic effects.
