Hypothyroidism is the abbreviation for hypothyroidism, which is a series of clinical manifestations caused by the inability of the thyroid gland to secrete enough thyroid hormones to meet the normal physiological needs of people for various reasons. This disease is a group of clinical syndromes caused by the lack of endocrine hormones in the body. It is not effective to use Chinese medicine alone, because there is no Chinese medicine that contains thyroid hormone, so hypothyroid patients need to be treated with regular western medicine, and the most commonly used in clinical practice is Eugenol, which is a levothyroxine tablet that contains a stable thyroid hormone component and is suitable for most hypothyroid patients.
