In an RCT with 60 patients with HT, Qijian-Goiter-eliminating decoction (1 decoction per day divided into two equal doses, twice daily) significantly decreased the levels of TPOAb, TGAb, IL-1β, IL-18 and MDA, and increased the levels of serum SOD, GPx, and total antioxidant capacity (TAC) compared to selenium supplementation (150 μg twice daily for 12 weeks); this treatment then seems to relieve oxidative stress and decrease the level of inflammatory factors [65]. The gene discussed is IL1B; the disease is hematocrit.
