#สารส้ม

For centuries, alum, known in Thai as “สารส้ม” (san-som), has shimmered as a crystalline cornerstone in Southeast Asian households. Its appearance in the home—whether a chunky mineral block resting beside a rural water container or a fine powder in bathroom cabinets—reveals a legacy interwoven tightly with both daily life and healing customs. But as modern science explores ancient remedies, alum emerges as a unique case: a mineral of almost mythical versatility, yet one that requires scrutiny for safety in contemporary times.
