The benefits and effects of cupping therapy can achieve the goals of unblocking the meridians, adjusting Qi and Blood, balancing Yin and Yang, invigorating blood circulation, dissipating blood stasis, reducing swelling and alleviating pain, expelling wind and dampness, dispelling cold, and promoting health. By creating negative pressure within the cup, passive hyperemia occurs in the superficial tissues, leading to the dilation of local blood vessels, increased blood flow, and accelerated blood circulation. This improves the blood supply to the skin, enhances the vitality of deep skin cells, increases the permeability of blood vessel walls, and enhances the phagocytic ability of blood cells, resulting in a rise in local temperature. Additionally, it strengthens local tolerance and the body’s resistance, boosts immunity, and promotes recovery from illness.
When performed according to the indications and techniques of cupping, there are no adverse effects. However, contraindications for cupping include acute local inflammation and hemorrhagic diseases, as cupping may exacerbate these conditions.
