Hyperthyroidism is a medical condition in which the thyroid gland produces too much thyroid hormone (called T3 and T4). As the thyroid gland plays a crucial role in regulating metabolism and has effects on nearly all organs in the body, an overactive thyroid can have far reaching effects on health and body functioning. The most common cause of an overactive thyroid is Graves Disease. Graves Disease is an auto-immune illness in which the immune system begins to attack parts of ones own body - in this case the thyroid gland. Other causes of Hyperthyroidism include nodules on the thyroid gland, inflammation of the thyroid (thyroiditis) and over-treatment of hypothyroidism (underactive thyroid). If left untreated, hyperthyroidism can be a significant threat to health and may cause serious complications. Mild hyperthyroidism often responds well to complimentary medicine and a holistic approach (including diet). ThyroSoothe is a 100% herbal remedy containing herbs known for their ability to soothe and normalize the overactive thyroid and related symptoms, naturally decrease levels of T4 and TSH and inhibit the binding of antibodies to the thyroid.
