This magnesium chloride is like no other in the world. It is harvested from a lake in the Tibetan Plateau, 3200m above sea level, pristine and isolated from pollutants and contaminants! Provides essential minerals to your body, skin & cells. Use in a bath, salt scrubs & foot soaks. Minerals are absorbed through the skin. Additional benefits include greater energy, more relaxed muscles, better sleep, improved mental function, alleviates headaches, arterial health, better reproductive function and balances hormones. Aids in the detoxification of toxins and metabolic waste products. It's a great idea to have an magnesium salt bath (using 1/2 a cup - 1 cup of salts) after a big workout, to prevent muscle pain and soreness. Store in an airtight container and keep in a cool, dry place. If kept open the salt will absorb moisture from the air and melt. For external use only, we recommend patch testing before use.
