Non-small cell lung cancer （NSCLC） accounts for approximately 80% of lung cancer cases, and approximately 75% of patients are diagnosed in the middle and late stages. The treatment methods mainly include surgery, chemotherapy, radiotherapy, molecular targeted therapy, traditional Chinese medicine therapy, and immune therapy. We summarize the current status of lung cancer-related treatment options and targets.展开更多
Ginseng is a traditional rare medicinal herb in China. It is a disputable problem whether or not the rhizome of ginseng should be cut off and discarded because it has been considered to have an emetic action.
