Tanshinones isolated from Danshen were able to ameliorate peroxidative damage, adjust the level of serum superoxide dismutase (SOD) and malonaldehyde (MDA), and inhibit the secretion of IL-6 and TNF-α, thus attenuating rheumatoid arthritis (RA) [71]. The gene discussed is IL6; the disease is rheumatoid arthritis.
