Lingzhi Fuzheng Granules

A randomized double-blind method was used to study patients with stage III and IV non-small cell lung cancer. Lingzhi Fuzheng Granules were used to treat patients who had completed chemotherapy for non-small cell lung cancer. The patients took Lingzhi Fuzheng Granules orally for 3 months and underwent clinical observation for 6 months. The purpose was to determine whether the drug: 1. Can it improve the patient's immune function and reduce the recurrence and metastasis rate; 2. Can it prolong the patient's progression-free survival; 3. Can it improve the patient's quality of life; 4. Whether it has major adverse effects.
