What is the origin of potassium alum stone?
More than 3,000 years ago, alum stone was used by our ancestors for its natural deodorizing properties. As noted in the Ebers Papyrus, 1550 BC, which is one of the oldest medical documents ever discovered, alum was listed as having cosmetic properties. The absence of chemicals, perfume, and alcohol makes alum an ideal solution for even the most sensitive skin.
