Mallowsweet, along with Sage, is a magical herb that Centaurs burn to observe the fumes and flames, in order to refine the results of their stargazing.[1]

Mallowsweet is also an ingredient of the Extra-Sweet Butterbeer concocted by Madam Rosmerta, and is kept in the Potions Classroom of Hogwarts School of Witchcraft and Wizardry; thus it is likely an ingredient used to brew certain potions.[2]
