The most commonly used herbal medicine to treat lung cancer is ginsenoside Rh2, also known as protector of life, an active anti-cancer substance taken from ginseng. Ginsenoside Rh2 can act on proliferating tumor cells, especially the more sensitive M-phase, so that cancer cells cannot make DNA replication and reduce cancer cells to enter the next division cycle, thus achieving the effect of inhibiting cancer cell proliferation, shrinking tumors, controlling the disease and improving patients’ quality of life. Pure natural Chinese herbal medicine has better therapeutic effect and has special efficacy on advanced malignant tumors as well as lung cancer, and it is safe and does not cause great harm to the body as well as toxic side effects. Chinese herbal medicine has special function on shrinking tumor blood vessels.
