A Review of Integrative Plant-Based Approaches for the Management of Hashimoto Thyroiditis

Hashimoto Thyroiditis (HT) is one of the chronic autoimmune diseases of the thyroid gland which is characterized by the gradual destruction of the thyroid and the development of hypothyroidism. It occurs mainly in women and is caused by genetic dispositions, malfunctioning of immune system, environmental factors and imbalance of hormones. The levothyroxine drug therapy stabilizes thyroid hormone clearance but does not complete recovery of dissimilar symptoms or recovery of the immune dysfunction. This review examines the nature of plant-based and nutritional intervention as an add-on in the management of HT. An in-depth analysis of recent studies was done in regards to the plant-based therapies, phytochemicals and nutritional interventions applied to Hashimoto Thyroiditis. A special focus was made on medicinal plants like Withania somnifera, Curcuma longa, Nigella sativa, and Prunella vulgaris, and findings of preclinical, clinical and emergent nano-phytomedicine studies. Evidence suggests that there is the possibility that bioactive phytochemicals have immunomodulatory, antioxidant and anti-inflammatory activity. Adaptogens and nutritional components are effective to stabilize a Hypothalamic-Pituitary-Thyroid (HPT) axis and normalize stress-induced endocrine sequelae. Nano-phytomedicine therapy has been found to be a promising clinical method towards enhancing the bioavailability and specificity. Weaknesses are lack of uniformity, minimal clinical trial evidence as well as the possibility of drug interactions associated with herbs. Nutritional and plant-based therapy is an alternative and complementary form of treatment to conventional HT. The direction of the future is to work in the arrangement of genomics, microbiome science, and digital health with a view to enabling personalized strategies. There are also therapeutic opportunities in targeting the gut-thyroid-immune axis using pre and probiotics and polyphenol-rich diets. Collectively, such strategies offer a potentially bright future with regards to safer, customized, and more efficient HT management.
