Just a note of caution when using clay internally, my experience with it was that after few months of use ( the recommendation was to drink the water in which green clay was sitting over night every morning for 3 months) I developed several kidney stones and ended up at the emergency in excruciating pains. Wouldn't recommend this experience to anyone ;) Luckily was able to resolve it with just few doses of Boswellia tree resin when all the conventional medication failed,
To add another word of caution with the internal use of clay: I once took clay and chlorella during the same day and it seemed to turn into some kind of cement in my intestines. I was pretty concerned and it was definitely not fun, so I personally would recommend using caution to anyone thinking of using clay and chlorella at the same time, or just use one of the two and avoid mixing all together. I have the same concern with mixing clay and activated charcoal, however I'm not sure if that would cause the same issue.
As well, overall, I found charcoal and chlorella to generally be more effective for me than clay and haven't had any trouble mixing the two of them.
