It is also known as levothyroxine sodium tablets. The main effect of levothyroxine sodium tablets in clinical practice is to treat congenital hypothyroidism, or hormone replacement therapy for children and adults with hypothyroidism due to various causes. It can also be used to diagnose hyperthyroidism and to perform suppression tests to diagnose hyperthyroidism. Since eugenol is a thyroid hormone, the main function of thyroid hormone is to promote the synthesis of protein and the metabolism of sugar and fat, so when thyroid hormone is secreted in excess, such a disease is called hyperthyroidism, and patients with hyperthyroidism often experience an increase in the number of stools and a loss of weight. So when you take too much Eugenol, it will cause weight loss, not weight gain.
