SALT BLOCKS Salt rooms made of salt blocks give benefits to all patients who have allergic asthma, high blood pressure, nerve pain, kidney and liver diseases and are also useful in many diseases. The patient spends about 12 hours in these salt rooms and gets rid of many diseases without any medicine. These salt rooms can also be made in the houses from which all the family members can also get benefit, that is they can stay healthy. SCIENTIFIC EXPLANATION The rays emitted by the salt crystal lamps contain a large amount of negative ions, which heal the patient by filling the lack of oxygen in the atmosphere, which helps the patient get rid of his disease naturally. NOTE: Oxygen molecules (negative ions) means oxygen molecules have a negative valence.
