Taohong Siwu decoction, for instance, can attenuate ischemia‐induced cerebral injury in middle cerebral artery occlusion reperfusion (MCAO/R) rats by reducing the levels of pro‐inflammatory cytokines such as tumour necrosis factor alpha (TNF‐α), interleukin 6 (IL‐6) and interleukin‐1beta (IL‐1β).24 This evidence concerns the gene IL6 and ischemia.
