Essiac Tea Herbs - Where Can I Buy Quality Original Authentic Formula Online?

Does anyone know where I can buy Essiac Herbs online that has the ratio of herbs of the original Rene Caisse Formula, that is reasonably priced and is high quality herbs and that others have had success with?

I've gone to several sites that their herbs just say "Essiac blend" but I need to know if it's the exact authentic formula.

The photo of the Essiac Herbs at Mountain Rose Herbs looks very pale.

The photo of the herbs at Clarkia looks great but I don't know if they are high quality herbs.

I just found out my beloved cat has liver/lung cancer (2 inches) and I want to try this, for my own health as well.

Thanks so much in advance
