Catawiki cannot guarantee or be held liable for these suggested attributes which have no scientific evidence and cannot be considered a substitute for traditional medical treatment. Terahertz stone comes from Japan and is a silver-colored, man-made ore containing silicon and titanium, among other minerals. The ore was developed in Japan. It has the unique property of emitting radiation with a vibration measured in the terahertz (THz) frequency. According to Japanese beliefs, its beneficial properties lie in the fact that THz radiation lies in the range between light and radio waves and therefore possesses the properties of both. This means it is capable of improving both organic and inorganic material and activating DNA. It raises body temperature and counteracts hypothermia, improves blood circulation, and prevents and heals illnesses. It is suitable for people who experience pain in their hands or feet or suffer from cold hands or feet. It stimulates cells, thus regulating the body's balance and promoting physical mobility. On a mental level, it aids concentration and creativity. According to physician and medical doctor Hiroki Shima (M.D., Ph.D.) and his book on "The Essence of Health" (titled "Here the Essence of Your Health"), health is determined at the quantum level. This is because quantum is the ultimate field where the molecular world is constructed, where matter still possesses the properties of both particles and wavelengths. Disharmony in the quantum field plays a major role in diseases and disorders in the human body. Shima has found scientific evidence that under the influence of terahertz waves, the quantum field is normalized. This provides effective treatment for serious illnesses and promotes overall health. It can also protect against negativity and stress in other forms. Terahertz stone can stimulate the inner body and free the mind from stress and worry. It is an excellent stone for those who have to perform mentally demanding roles/jobs or who overthink. Research into its medical applications for the human body is still ongoing. Nevertheless, various beneficial properties are already attributed to it. Terahertz ore is said to be an excellent stone for overall health and is therefore becoming popular. Terahertz (THz) radiation is in the electromagnetic spectrum and lies between microwaves and far infrared. A characteristic of far infrared is that it warms up and can melt ice. A kilohertz is 1,000 hertz, a megahertz is 1 million hertz, a gigahertz is 1 billion hertz, and a terahertz is 1 trillion hertz. Terahertz plays a major role in science, including astronomy. The special feature of terahertz ore is that it continuously emits terahertz radiation. Shipping registered.
