Lung deficiency with a lot of white phlegm can be treated with oral medications, as well as acupuncture, moxibustion, or through dietary therapy. Oral medications: Chinese medicines that benefit qi and resolve phlegm, such as astragalus, tangerine peel, codonopsis, licorice, and platycodon, can be taken, or proprietary Chinese medicines or formulas can be taken under the guidance of a physician. The adverse effects and contraindications of the above drugs are not clear. Acupuncture and moxibustion: Usually, people with cough and phlegm can have acupuncture or moxibustion on Lung Yu, Fenglong, and Spleen Yu points in order to regulate qi and resolve phlegm. Food therapy: You can choose white radish, Coix lacryma, yam and other medicinal ingredients to make porridge. White radish can dissolve phlegm and clear the lungs, while Coix Seed strengthens the spleen and dispels dampness. Yam is good for the lungs and spleen. If you are not feeling well, do not self-medicate, please seek medical advice under the guidance of a physician.
