JOINT PROBLEMS: Minerals have an alkalizing effect on the body. Natural health practitioners have observed that this has an anti-inflammatory effect, easing painful conditions such as arthritis.
BACK PAIN: Whether you eat or bathe in them, mineral-rich salts tend to relax. This is largely due to magnesium, which is needed for muscles to relax. Low levels of magnesium are associated with muscle cramps.
BONE STRENGTH: Unrefined rock salts are rich in minerals needed for bone strength. Apart from calcium, bones use phosphorus, magnesium and other minerals as building materials.
