"Ozone therapy has been proposed as an immunomodulator and cellular metabolic activator which shows long-term anti-inflammatory effects and serves to reduce further the proinflammatory factors... ozone applied externally ameliorated the inflammatory reaction of RA without toxicity or serious side effects. Therefore, ozone injected into the knees of RA patients could become a valuable treatment, and we confirm the interactive mechanism between ozone and RA-SFc."
"MTX+ozone increased the MTX clinical response in patients with rheumatoid arthritis. No side effects were observed. These results suggest that ozone can increase the efficacy of MTX probably because both share common therapeutic targets. Medical ozone treatment is capable of being a complementary therapy in the treatment of rheumatoid arthritis."
