It is generally believed that dandelion tea has a therapeutic effect on symptoms such as cough, chest pain and coughing up phlegm caused by lung carbuncle, but there is no information showing that it has a therapeutic effect on lung nodules. Dandelion is bitter, sweet, cold in nature and belongs to the liver and stomach meridians. As dandelion can help clear heat and detoxification (removing heat and toxicity from the body), reduce swelling and dissipate nodules, it can treat lung carbuncle. Therefore, the use of dandelion tea can, to a certain extent, assist in the treatment of coughing, chest pain, coughing up phlegm and other symptoms caused by lung carbuncle, and can effectively reduce the discomfort. However, for the lung nodules themselves, dandelion tea does not play a therapeutic role and cannot control the progress of lung nodules. In addition, dandelion also has the effect of diuretic and diaphoretic (improving the problem of dribbling in urine and urinating in small amounts). Drinking dandelion tea can also be used clinically to assist in the treatment of eye redness, sore throat, intestinal carbuncle (carbuncle occurring in the intestines and bowels, manifested by fever, pain in the right abdomen, and palpable lump), breast carbuncle, and damp-heat jaundice. In summary, it is recommended that patients with pulmonary nodules go to the hospital, cooperate with the doctor to actively treat, do not self-medication.
