Traditional Chinese medicine has a long history in treating tumors. More and more researchers have paid more attention to it. At present, many studies have proved that traditional Chinese medicine extracts such as astragalus, turmeric, ginseng, coix seed, and gallbladder can inhibit tumor cell proliferation, and have synergistic effects when used in combination with radiotherapy and chemotherapy Its mechanism of action is mostly related to regulating the cell cycle, inhibiting the expression of cancer-related genes, and inducing apoptosis.
