Historically used for centuries, alum powder is an astringent compound with numerous applications, from pickling food to creating natural deodorants. Despite its long-standing use, its reputation as a traditional remedy has led many to question: is alum powder healthy for consumption or even topical application?.

According to the World Health Organization's Joint FAO/WHO Expert Committee on Food Additives (JECFA), a tolerable weekly intake has been established for aluminum, a component of alum. This raises questions about whether it is safe to use alum in food, a practice historically associated with pickling and baking.
