Lung nodules do not have a corresponding name in TCM literature, but can be categorized as “cough” or “lung accumulation” according to the specific symptoms. If you have lung nodules, you can take Xiao Jindan within the scope of indications, but Xiao Jindan is not a cure for lung nodules. Xiao Jin Dan is a traditional Chinese medicine formula composed of Bai Jiao Xiang, Prepared Wooden Turtle, Chen Mo, etc. This formula has the effect of resolving phlegm, dispelling dampness, eliminating blood stasis and clearing collaterals. It is effective in treating phlegm nuclei (lumps swollen up like nuclei under the skin), flow injection (multiple abscesses originating from deep muscles), breast lumps, yin gangrene (a general term for a class of slow-acting yin sores and ulcers), thyroid tumors, and deep abscesses, etc. After taking this formula, a few cases may have the symptoms of phlegm, dampness, blood stasis and circulation. Side effects such as stomach discomfort and loss of appetite may occur in a few cases after taking the medicine, and the discomfort can be alleviated by taking it after meals. Skin allergy is occasionally seen in external use. Caution should be exercised in cases of emaciation, red cheekbones, hot flashes and night sweats (abnormal sweating after going to sleep and stopping after waking up), and heartburn and heat (heat in the palms of the hands and the hearts of the feet, and self-consciousness of the heart and chest being irritated and hot). Xiaojindan is not a contraindication to the use of lung nodules, in the scope of the indications of Xiaojindan can be eaten, but Xiaojindan does not have a role in the treatment of lung nodules. It should be noted that the formula of wood turtle seed is poisonous, this drug needs to be standardized use under the guidance of traditional Chinese medicine practitioners to identify the evidence. If there is no improvement, please go to the regular hospital in time, improve the relevant examination to clarify the diagnosis, standardize the treatment, so as not to delay the condition.
