Many data have shown the anti-oxidative effects of TCM on PF, for example, Danggui Buxue Tang and TJ-19 (two different TCM compounds) could attenuate BLM-induced PF via increasing SOD activity and decreasing MDA content (Yang et al., 2010; Zhao et al., 2015). Here, SOD1 is linked to pemphigus foliaceus.
