A study has shown that moxibustion can regulate inflammatory cytokines and VEGF in RA [14], which can also significantly inhibit the proliferation and secretion of RA synovial cells, thus effectively improving the synovial inflammation hyperemia, edema, and joint cavity effusion and having good anti-inflammatory, analgesic, and immunomodulatory effects [15]. Here, VEGFA is linked to rheumatoid arthritis.
