[Three Cases of Herbal Medicine Coadministration Contributed to Cancer Control and Reduced Anticancer Drug Side Effects].

We encountered 3 cases suggesting that coadministration of herbal medicines may reduce the side effects of anticancer drugs and reinforce cancer growth control. In 2 cases, on observing anticancer drug resistance, it was possible to regain control of cancer growth by coadministering herbal medicines. In the remaining 1 case, thrombocytopenia was observed during chemotherapy, which could be avoided by coadministering a herbal medicine. If the expected effect is not obtained even after herbal medicine administration, it is important to consider additional herbal medications.
