Hyperthyroidism belongs to the category of gall tumors (equivalent to thyroid tumors) in Chinese medicine. Huang Yao Zi, seaweed and kombu can generally be applied to treat hyperthyroidism. The efficacy of Huang Yao Zi is to dissolve phlegm, soften and disperse knots (soften and dissipate hard lumps), clear heat and remove toxins. It is used to treat gall tumors, sore throat, poisonous snake bites, sores, carbuncles and poisons. Huang Yao Zi is poisonous, should not be taken in excess, such as over-served for a long time may cause vomiting, diarrhea, abdominal pain and other gastrointestinal reactions, and has a certain degree of damage to the liver and kidneys, so liver and kidney impairment and weak spleen and stomach should be used with caution. The effects of seaweed and kombu are eliminating phlegm, softening and dispersing knots, and inducing diuresis and swelling. They are mainly used in treating scrofula (mainly refers to cervical lymph node tuberculosis), gall tumors, phlegm (pathological products formed by impaired metabolism of water and fluid), edema, testicular swelling and pain. It should be noted that seaweed should not be used with licorice. Adverse reactions and contraindications of Seaweed and Kombu are not known. Before using the medicine, a doctor should be asked to carry out identification and use the medicine under the doctor’s guidance. Do not use the medicine privately as it may cause damage to the organism.
