Certain substances in ginseng have been found to possess anti-cancer properties. Research conducted by the Chinese Medicine Journal found that ginsenosides have anti-tumour effects and can damage the prostate cancer cells, ovarian cancer cells, neurobastoma cells and lung adenocarcinoma cells. It can also inhibit cell cycle progression, thus slowing down the growth of cancer cells. A study by Vanderbilt-Ingram Cancer researchers found that consumption of ginseng after breast cancer diagnosis improved chances of survival and quality of life.
