Definition: The term "prepurized" is used in the medical field to describe a substance that has been prepared or processed so that it no longer contains essential nutrients, vitamins, and minerals. This process involves removing contaminants from the original raw material, such as water, dirt, or other impurities, to create a pure form of the substance. Prepurized substances are often used in medicine to treat conditions like kidney disease or cancer, where the body's natural defenses are weakened by exposure to toxins.
