Results: Initial improvement was apparent after the administration of Modified Er-Xian Decoction. After 3 months of treatment, the patient 's Spleen-Kidney deficiency index improved significantly, and thyroid hormone levels returned to normal. Conclusions: In this case report, symptoms and biochemical improvement were confirmed based on a single herbal medicine prescription for subclinical hypothyroidism. It is necessary to verify the effect of this prescription through well - established clinical trials.
