The presence of black blood from cupping indicates the presence of cold and blood stasis in the patient’s body. This can be treated clinically by paying attention to warmth, making dietary adjustments, not eating too cold food, not eating too stimulating food, etc. The black blood in cupping is clinically caused by premature blood clotting, which means that the blood lacks a certain amount of oxygen and has an unreasonable cellular distribution, etc. It can be treated by medication. For example, you can use some blood activating drugs such as nitrate capsule, ginkgo biloba extract, and aspirin enteric tablets, etc. These can help to improve the blood flow and adjust the patient’s symptoms, such as precordial discomfort, coronary artery disease, and insufficient blood supply to the brain, all of which can play a significant therapeutic role.
