Dandelion is cold in nature and sweet in taste. Drinking it in water has the effect of clearing heat and detoxifying the body, eliminating swelling and dissipating nodules, and diuretic and laxative. According to Chinese medicine, liver stagnation and liver fire lead to blood stagnation and blood stasis, resulting in thyroid nodules. Therefore, patients with thyroid nodules can drink dandelion as a substitute for tea on a daily basis to clear the heart and diuresis and eliminate stagnation in the body, which can assist in the treatment of thyroid nodules. However, it is important to note that the effect of dandelion in water is limited and should not be used as a substitute for medication. If thyroid nodules grow rapidly or other uncomfortable symptoms appear during this period, you should seek medical help promptly. Dandelion is cold in nature and is not good for the health of the spleen and stomach when taken for long periods of time, so it should not be taken for long periods of time.
