[Current status of traditional Chinese medicine on reversing tumor multi-drug resistance].

Multi-drug resistance (MDR) is one of the major obstacles to successful chemotherapy for tumors. Traditional Chinese medicine that can reverse MDR has been intensely studied because of its low toxicity, high efficacy and multi-targets. In recent years, more and more traditional Chinese medicine (TCM) has been found to be effective in reversing MDR. In this review, we analyze the current status of traditional Chinese medicine on reversing tumor MDR and describe recent progress on it.
