Zinc is a metal and number 30 in the periodic table. The earliest record comes from India about 3,000 years ago. The alchemist, Paracelsus, is thought to have named the element. Alchemical names include philosopher’s wool and nix alba. In current metaphysical texts zinc is related to the planet Mercury, the heart chakra, heart, circulation, respiration and nervous system. It helps harmonize and integrate the body systems.
It is an essential mineral for the human body with about 2 to 3 grams in each human body. Zinc is considered an essential trace element for humans, animals, plants and microorganisms. In fact, it is the only metal that appears in all enzyme classes. Between 100 and 300 different enzymes require zinc and up to 3,000 out of 100,000 proteins contain zinc.
