Kaempferol is a natural flavonol, a type of flavonoid, that has been isolated from tea, broccoli, Delphinium, Witch-hazel, grapefruit, brussels sprouts, Kaempferia galanga and other plant sources. 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 powder are more effective than the additive effects of each flavonoid.

(1) Kaempferol is a strong antioxidant and helps to prevent oxidative damage of our cells, lipids and DNA. Kaempferol seems to prevent arteriosclerosis by inhibiting the oxidation of low density lipoprotein and the formation of platelets in the blood.

(2) Studies have also confirmed that kaempferol acts as achemopreventive agent, which means that it inhibits the formation of cancer cells.Kaempferol induces apoptosis in glioblastoma cells through oxidative stress.

(2) Kaempferol can inhibit the apoptosis induced by H202 in neonatal rat cardionyocytes. The protective effects could be related to their antiocidant activity and its ability to regulate the expression of Bcl-2,
Bax, Caspase-3 protein.

(3) Kaempferol is a blocker of voltagegated potassium channels in pyramidal neurons of rat hippocampus. The electrophysiological effects of kaempferol may be one mechanism of its protective effects on rat hippocampal neurons in acutely transient hypoxia.

(4) Kaempferol owe to the strong antioxidant properties, can scavenge superfluous superoxide free radicals in human body, preventing DNA and cells from oxidative damage. It show pharmacological effects in anti-tumour, anti-inflammation and anti-senility, etc.

(5) Kaempferol has the effect of anti-epilepsy, antispasmodic, anthelone, antiulcer, choleretic, diuretic activity and relieving cough.
