Alum or other astringents that stop the flow of blood can be used only if they are in which form?

Explanation:
Alum and similar astringents work by constricting small blood vessels and promoting the formation of a clot right at the bleeding site. To do this effectively, they must be applied directly and controllably to the wound. A liquid form lets you dab or lay a thin, uniform layer exactly where the bleeding is, reaching tiny irregularities and stopping the flow quickly. Powders can scatter, blow away, or fail to stay in place on the wound, and pastes are thicker and slower to act. The liquid form provides immediate, precise application that delivers fast relief from bleeding.
