ALKALIZING MINERAL CESIUM THERAPY?? or HIGH pH Therapy???

Has anyone tried a high alkalizing pH therapy (like using the mineral cesium). One web site that explains this therapy using cesium is www.wizardofeyez.com/cesium.html. It appears to rapidly kill off cancer cells within a few days. I am very concerned about this because of the extremely toxic effects on the body with this quick die off. I am taking care of a friend that has lung cancer with probable other involvement throughout the body. She has lost all body fat although her weight is 113 she still looks like she only weighs 90 pounds. I fear that she is at the last final stages and can't go on for much longer. She has such a tremendous problem, and has had for 1 year or so, with her taste being so bitter and food textures are like chewing cardboard and cotton, so that she just can't eat much at all. I would really like to try this therapy on her but am afraid of bringing down what little strength she still has. I know a gradual alkalizing would be just as effective in the long run, but with time not being on our side; oh well...Thanks for any advice.
