As the largest endocrine gland in human body, the thyroid plays a vital role in regulating human growth and metabolism through synthesizing thyroid hormones. Malfunctions of the thyroid can cause serious thyroid related diseases including goiter, autoimmune thyroid disease (AITD), and thyroid cancer. Among these thyroid-related diseases, goiter is commonly found in the general population. Clinically, it involves either diffuse or nodular goiters based on the thyroid histology. The cause of goiter is complicated and can be associated with a euthyroid, hyperthyroid, or hypothyroid metabolic state. People with goiter tend to have a normal life, but some suffer from discomfort, such as pain, airway blockage and esophageal blockage. In addition, nodules may form in the later stage of goiter that can aggravate the disease and even lead to thyroid cancer. Therefore, medications for the prevention and early intervention of goiter and its development are urgently required.

Thyroid hormone plays an important role in regulating huamn body metabolism. Therefore, it is of great reference value to explore the therapeutic effect of Prunella vulgaris in treating metabolic diseases in the future. Prunella vulgaris has been studied for its protective role in various metabolic disorders, including diabetes. Prunella vulgaris is suggested to be a good therapeutic inhibitor for diabetic vascular disease through exerting anti-inflammatory effects via the ROS/NF-κB pathway. The caffeic acid extracts of Prunella vulgaris are known to increase serum insulin levels, and attenuate alpha-amylase and alpha-glucosidase, therefore  vulgaris is suggested to be a potential agent for ameliorating type I diabetes.
