👉 A coagulant is a substance that can dissolve or break down larger particles, such as blood cells, bacteria, and other substances. It acts by binding to these particles, causing them to adhere to each other and prevent their passage through the blood vessels. In medical terms, coagulants are used in blood-thinning medications like aspirin and warfarin to prevent excessive bleeding. They can also be used as a means of sterilizing medical equipment or cleaning surfaces with viruses.
