What is Alum?

Alum is an odorless, colorless, and transparent substance found in the form of crystalline blocks or granular powder, with a mildly sweet, astringent taste.

Naturally occurring alum shells are used to make it.

Alum melts at 90-degree centigrade temperature and if further heated to 200 degrees centigrade, its crystals lose water and turn into a concentrated or solid substance, which is known as Brunt Alum.

Pure alum is completely transparent and completely soluble in water. On heating it becomes porous.

It comes in two colors white and light pink, but white is used more in homes. In Ayurveda, it is used in the form of Bhasma. Bhasma is prepared by evaporating alum.

Alum is widely used in Unani systems of medicine, including Ayurveda.
