Aswagandha root has historical use in the treatment of underactive thyroid. In this study, ashwagandha root extract was administered for 20 days by gastric intubation of male mice. The thyroid hormones T3 and T4 increased. Furthermore, ashwagandha root extract significantly reduced hepatic lipid peroxidation. And the activity of antioxidant enzymes such as superoxide dismutase and catalase were increased.
According to the researchers:
“These findings reveal that the ashwagandha root extract stimulates thyroidal activity and also enhances the antioxidant activity in liver tissue.”
