IL6 and cerebrovascular disorder: Pan et al., 2014 [68], and Zhu et al., 2012 [69], showed the integrated PK of baicalin, baicalein, geniposide, palmatine, and berberine, the main effective ingredients in Huang-Lian-Jie-Du-Tang in middle cerebral artery occlusion (MCAO) rats, and found that the correlation with the anti-ischemia index (Interleukin 6 (IL-6), tumor necrosis factor (TNF-α), superoxide dismutase (SOD), glutamic acid (Glu), and MDA) in the serum was good, which would provide comprehension better understanding of cerebrovascular disease as Huang-Lian-Jie-Du-Tang is used in clinical practice.
