Daily Health Tips
Salt as Treatment
Some days are better for rest and reflection than for starting new endeavours. Today, rest your weary bones. Simply taking time to rest is beneficial for the most common of all chronic health conditions, osteoarthritis. And the most appropriate "medication" may be as simple as salt. Bathing in the sea is best. The natural iodine in the sea water is said to relieve arthritis pain. As is well-known, iodine regulates the acid-alkaline balance in the blood and tissues, helps to repair and regenerate worn out tissues and nourishes the skeletal structure. It enters into the thyroid gland's secretion. The hormone uses this iodine to nullify germs in the bloodstream and to create a self- cleansing of internal toxaemia. Not everyone, of course, can bathe in the sea. If sea bathing is not possible, relax for 30 minutes every night in a tub of warm water in which a cupful of sea salt has been mixed. The minerals in the sea salt, especially iodine, can be absorbed through the skin pores. This will help correct an internal imbalance. Be sure your water is warm. After your bath, drink warm water with the juice of a lemon. The lemon is a natural solvent for uric acid crystals that attack the joints.
