Shungite is known for its incredible healing and protection properties, including boosting energy and immune system, balancing mind and emotions, protecting from harmful EMFs, detoxification and purification of the body.
Shungite has been used as a folk medical treatment since the early 18th century. Peter the Great set up Russia's first spa in Karelia to make use of the water purifying properties of shungite, which he had himself experienced. He also instigated its use in providing purified water for the Russian army. The anti-bacterial properties of shungite have been confirmed by modern testing.
Shungite has been used since the middle of the 18th century as a pigment for paint, and is currently sold under the names "carbon black" or "shungite natural black".
