Today we’ll be focusing on a study just recently released about the ability of Flavokavain-C (FKC) to cause cellular death in human colorectal cancer [1]. This study used a culture of cells known as HCT 116. These cells are human colon cancer cells, and are used in various biomedical studies involving colon cancer proliferation, cell biology, intestinal immunity, and inflammation [2]. This study used nude mice, which are genetically modified to have an extremely suppressed immune system. A side effect of this mutation is also the loss of the mouse’s hair. They used this type of animal in this study because they can accept tissue and tumor grafts without producing a reaction immune response. These mice are commonly used in research to test new methods of imaging and treating tumors [3]. This study found FKC inhibited the growth of colorectal cancer in a dose dependent manner. When treated with 3mg/kg of FKC these cancers slowed growth on the order of up to 52%.

This fact alone is enough to celebrate in this study, however there is one large implication that shouldn’t be left without emphasizing. Most standard chemo regimens are extremely toxic to the body, as while they may be specific in treating cancer, they tend to kill other cells as well. Cisplatin is a potent chemotherapy drug used in many types of cancer treatment. It was used as a positive control in this study. Cisplatin has common side effects such as kidney damage, vomiting, bone marrow suppression, heart disease and a host of other side effects. Flavokavain-C was studied for toxicity and it was found that 1mg/kg and 3mg/kg dose amounts were found to not cause damage to any organs, and not have a detrimental physiological effect in the mice. Evidence put forth in this study shows FKC being as or more effective than the standard chemo drug, Cisplatin on reducing tumor volume size while providing virtually none of the standard chemo side effects. The closer we look at this amazing plant, the more surprises we find.

Each Fact of the Day is a must read! Thanks. This is yet another significant study and I remain surprised that the wider audience continues to ignore the potential of this plant and/or demonstrates contempt by language or perceived artful humor. On the good side established institutes such as Memorial Sloan Kettering Cancer Center (MSKCC) now place "kava" on their website as possibly preventing, curing various cancers. On the bad side they keep the liver myth alive even though the kava cancer prevention studies they cite always comment that they observed no toxic liver reactions. Granted MSKCC says "rare".

Thanks. One more please :)
How was the FKC administered. Was it injected into the bloodstream, injected directly into the tumours, or given orally?
