Kaempferol seems to prevent arteriosclerosis by inhibiting the oxidation of low density lipoprotein and the formation of platelets in the blood. Studies have also confirmed that kaempferol acts as a chemopreventive agent, which means that it inhibits the formation of cancer cells. The flavonoids kaempferol and quercetin seems to act synergistically in reducing cell proliferation of cancer cells, meaning that the combined treatments with quercetin and kaempferol are more effective than the additive effects of each flavonoid. This was a conclusion from a study by ML Ackland et al (In Vivo, Feb 2005) titled "Synergistic antiproliferative action of the flavonols quercitin and kaempferol in cultured human cancer cell lines"". Kaempferol can help to fight cancer because it reduces the resistance of cancer cells to anti-cancer drugs such as vinbalstine and paclitaxel.
