Cationic components of our hot spring contain abundant magnesium ion and calcium ion in addition to sodium ion, the main component, and act as a sedative to suppress convulsion and inflammation. Our hot spring contains lithium ion in a quantity over 7 times higher than the standard for hot springs, and as a result is said to be effective as a sedative, as well as in stimulating cell activation (fatigue relief). Besides chlorine ion as the main anionic component, the hot spring also contains bicarbonate ion (main component of bicarbonate earth spring, also known as sodium bicarbonate spring) in quantity 1.7 times higher, and metaboric acid over 3 times higher, than the standard value for hot springs.
