Alteratives are considered “blood purifiers,” although this term can be misleading, as they don’t directly “purify” the blood in a medical sense. Instead, they support the body’s natural detoxification mechanisms, such as the liver, kidneys, and digestive system, to help eliminate waste and restore balance. Alteratives may enhance circulation, improve skin health, support the lymphatic system, and strengthen the body’s natural defenses. They are often used in chronic conditions or as part of long-term health maintenance, offering a steady, gradual improvement in bodily functions. Common examples of alterative herbs include burdock root, yellow dock, and sarsaparilla.
