Trace Minerals Zechstein Magnesium Oil ,8 Oz (Pack of 1)

The ancient Zechstein Sea in Northern Europe was a concentrated, pristine inland salt water sea that existed over 250 million years ago. Over time, the Zechstein Sea was slowly transformed into an underground mineral deposit 2,000 meters below the earths surface. It was created by a combination of flooding by sea waters and slow evaporation.
