If a lot of black blood clots come out during cupping with the skin intact, the patient’s qi and blood are stagnant and inactive, which can appear purple or black after cupping. In Chinese medicine, there is also acupuncture cupping, which is a way to release blood from the local skin by using plum blossom needles and trigeminal needles, and then perform cupping to remove the black blood stasis in the body, so that the microcirculation in the body can be reconstructed to activate the qi and blood and relieve pain. When black blood clots appear in cupping, it means that the body is very stagnant and requires treatment methods such as acupuncture cupping, gua sha and tuina to invigorate Qi and blood. At the same time cupping should pay attention to the interval, to wait for the new black stasis block, so that the body absorbed more completely before the next cupping treatment.
