Alum springs
Alumite spring water contains aluminum and sulfate ions and has an “astringent” effect that shrinks tissues and blood vessels by denaturing proteins. It is said to be effective for skin tightening and beautifying, as well as for chronic skin diseases, and is also called “eye water” because it is effective for cataracts and conjunctivitis.
