In TCM (Traditional Chinese Medicine), where cupping originates, cupping is practiced in both directions, both upwards and downwards. The main purpose of cupping in TCM is to improve the flow of qi (life energy) and blood in the body. The techniques and directions are adjusted depending on the treatment’s purpose, the person’s health condition, and specific needs. For maximum lymphatic massage, you should move the cup toward the lymph nodes, in a direction from bottom to top towards the nearest major lymph node.
