Supporting the immune system when cancer is involved is ESSENTIAL (even without chemotherapy)...echinacea not only supports the immune system, but is proven to beat many cancers (not to mention how many times throughout the century it's BEATEN cancer, but hasn't been "scientifically" documented).
Sadly/frustratingly, there are many people on CZ that won't believe something is true without "scientific documentation"...but we HAVE documentation that Echinacea is effective against cancer (and yes, Kidney cancer!)
PLEASE (!!!) be sure you get a quality product that's made from ONLY organic echinacea root....this is VERY IMPORTANT (there are many echinacea products on the market that contain little to no actual echinacea!!).
Clinical immunology Echinacea purpurea diminishes neovascular reaction induced in mice skin by human cancer cells and stimulates non-specific cellular immunity in humans (Echinacea purpurea, human cancers, angiogenesis, granulocytes, NK cells)
>>>Results: Echinacea preparation caused inhibition of angiogenesis induced by human lung and kidney cancer cells, as evaluated 3 days after intradermal cells injection. In human volunteers Immunal forte administration resulted in the stimulation of granulocytes metabolic activity and have increased the incidence of CD16+ and CD56+ NK cells in their blood.<<<
