The role of the lymphatic system inthe bodys metabolism and the removal of toxins from the bodyis definitely underestimated.The lymphatic system runs throughout the body and the amount of excess fat, waste products and toxins that are eliminated is largely dependent on the ability of the lymphatic system to absorb and eliminate these substances.The lymph nodes are also the main organ that produces immune factors toeliminate various inflammatory diseases and bacteria.These pollutants filtered by the lymph and the immune factors produced by the lymph are then transported by the circulatory system to other parts of the body for processing. We all know that the imbalance of thyroid hormone (TH) and thyroid-stimulating hormone (TSH) in the body is the direct cause of goiter, and substances such as cholesterol and triglycerides synthesized by the lymph affect the levels of this hormone and the Lymph can produce and secrete a substance called lymphokine, which directly affects the growth and development of the thyroid gland, thereby causing the thyroid gland to become enlarged.Therefore,the most basic treatment method can be achieved by regulating the function of the lymphatic system, which is more thorough than surgical resection and is also the safest method.
