Alum Granules (Potassium Aluminum Sulfate) (KAl(SO₄)₂·12H₂O) are a time-honored mineral ingredient celebrated for their potent astringent, purifying, and clarifying properties. Sourced from natural deposits and carefully processed into a fine, crystalline granulated form, these alum granules retain a brilliant, consistent appearance that makes them a versatile ally in both traditional herbal practices and modern applications. In Traditional Chinese Medicine and other herbal systems, Alum Granules are valued for their ability to tighten tissues, reduce minor bleeding, and draw out impurities. Their natural astringency supports wound healing and can help soothe irritated skin when used in topical formulations.
