Activated alumina is a porous solid made of aluminum oxide, or Al2O3. Though non-toxic, aluminum oxide is mildly irritating to skin and eyes with too much exposure. Please, do not eat.
Fun Fact: The crystalline form of Al2O3 is attributed to the precious gems ruby (pictured above) and sapphire, whose brilliant colors come from impurities in the crystal.
