The Effects of Zinc on Plants | Healthfully
Zinc is a metal that is necessary for human life, but dangerous at high concentrations. Zinc is used in batteries and pennies and die casting for cars. It occurs naturally in soil but more is being released into the environment by humans, especially from mining. Plants use zinc in creating chlorophyll, but in areas where soil is contaminated by zinc, only certain plants can grow. Zinc Carried ...
Zinc for Hair Loss - Does It Help?We know zinc is crucial in immune health, and because the HIV virus lays waste to the immune system, there is some evidence that zinc can help.
