Yan, male, 79 years old. He was diagnosed with lung cancer by Beijing Cancer Hospital in June 2000 due to cough with blood in sputum, fatigue and loss of appetite, and was recommended to survive for half a year with conservative therapy, considering that he was too old and had coronary heart disease and was not capable of surgery. The patient still had a cough with blood in the sputum, accompanied by fatigue and weakness, and was referred by a friend to the clinic on August 15, 2000. The patient had a yellowish complexion, fatigue, cough with blood in the sputum, a feeling of chest tightness and shortness of breath, irregular bowel movements, a pale red tongue with a thin yellow coating with flaking, and a stringent pulse. The treatment was based on the addition of Baihe Gujin Tang. Prescription: Lily 15g, Radix et Rhizoma Ginseng 12g, Erdi 12g, Radix Platycodon Grandis 12g, Chuanbei 9g, Radix Psidium Guadua 15g, Radix Medlar 12g, Radix Paeoniae Alba 15g, Radix Angelicae Sinensis 15g, Radix Glycyrrhiza Uralensis 6g, Radix Panax Ginseng 3g (divided), Radix Jiao Sanxian 30g, Rhizoma Yam 15g, Radix Maogan 15g, Radix Lotus Root 15g. After taking the formula for 1 week, the blood in the sputum was reduced, and after 2 weeks, the blood in the sputum was stopped, sputum production was reduced, appetite was improved, and self-consciousness was improved, but chest tightness and shortness of breath were often present. The patient’s general condition, appetite, and bowel movements were all smoothly regulated, with only occasional shortness of breath in the chest, which made the patient and his family very happy. The patient and his family were very happy. Then he passed the Chinese New Year, and in May he passed his 80th birthday, and all his friends and family were very happy. The patient often came for treatment once every 2 weeks until September 24, 2001, when I visited Malaysia for the last time before the prescription, asking him to take this formula for a long time.
