It is an artificial ore mainly composed of silicon (Si). It has been featured in various media as a health product, but there are still many areas that are still under research. Tera means 10 to the power of 12 (approximately one trillion). Hertz (Hz) is a word that represents the "frequency" or "vibration frequency" of electric current and radio waves. Terahertz ore, when translated literally, is said to mean "a stone that vibrates one trillion times." It is said that it was discovered after 1950 during a survey by the National Aeronautics and Space Administration (NASA) in the United States. According to NASA's announcement, terahertz is essential for life, and terahertz ore has come to be called "the light of life." These terahertz waves are also said to be emitted from all substances and living organisms in nature.
