I used the Cesium Chloride on my dog, however her cancer was excessively aggressive and Cesium does not work on everyone. For Lucky it did not work. When she was diagnosed she already had tumors in every of her organs, sizes between 2 cm and 10 cm.
I started the Cesium very late - a personal decision, as I was giving her various other things and I only started on the Cesium once another medication was pulled by the FDA. (Acemannan Immunostimulant - only available for pets)
Get those blood tests done!!!! DO NOT DELAY. The potassium you are taking may not be enough, even if you eat an alkaline diet. The amount indicated by Larry for Lucky was completely off for her, it should have been double the amount. Each person is different, so you have to have the electrolytes checked.
By the way, six grams sounds like a lot. I know some websites say six grams - have you checked with Larry, telling him your weight? More is sometimes not more. Please be careful.
I have heard of Essiac Tea, however that's one of the things that I did not give Lucky, so I can't give you more information on that.
