Your skin is an excretive organ that mirrors the condition of your intestines. When you take a brine bath, the salt minerals help your skin in the form of ions. Bio-energetic weak points will be balanced & your body's energy flow will be activated. To get the full benefits of a natural crystal salt bath, the right salt concentration is critical. The salt concentration has to be at least the same as the one of your body fluids (approximately 1%) to activate the osmotic exchange ratio. The formula for a 1% solution is 1.28 ounces of salt per gallon of water.
