The health benefits of

According to Wikipedia, kaempferol, a natural flavonoid, can be found
mainly in tea, broccoli, ginkgo[1], Delphinium, Witch-hatzel, grapefruit. It is a
yellow crystal. It is believed that kaempferol is what gives the flowers of
Acacia decurrens and Acacia longifolia their color. It has a melting point of
276-278C and it is slightly soluble in water.

Kaempferol is a strong antioxidant and helps to prevent oxidative damage
of our cells, lipids and DNA. Keampferol seems to prevent arteriosclerosis
by inhibiting the oxidation of low density lipoprotein and the formation of
platelets in the blood. Current evidences indicate that kaempferol not only
protect LDL from oxidation but also prevent atherogenesis through
suppressing macrophage uptake of oxLDL. [3]

Study showed kaempferol may have health benefit on people at risk of
cancer. Zhang Y and co-workers at Baylor College of Medicine
demonstrated its anti-cancer activities against pancreatic cancer cell lines
MIA PaCa-2 and Panc-1 in a recent study. Upon the treatment with 70
microm kaempferol for 4 days, MIA PaCa-2 cell proliferation was
significantly inhibited by 79% and 45.7%. The treatment with kaempferol
significantly inhibited Panc-1 cell proliferation. Furthermore, kaempferol had
significantly less cytotoxicity than 5-fluorouracil in normal human pancreatic
ductal epithelial cells. [1] Vivek Sharma and co-workers at National Brain
Research Center, India, found that kaempferol induced apoptosis in glioma
cells by elevating intracellular oxidative stress. Kaempferol also potentiated
the toxic effect of chemotherapeutic agent doxorubicin by amplifying ROS
toxicity and decreasing the efflux of doxorubicin. [2] Leung HW and
co-workers found kaempferol could induce human lung non-small carcinoma
cells H460 cell apoptosis.[5]

Kaempferol has anti-inflammatory activities and it may help protect certain
types of brain damage such as ischemic stroke. [4, 3]
