The burning doesn't sound like a good thing to be honest. Chlorella is supposed to soothe the intestines (it does mine). It increases the rate of growth of good bacteria by 4 times.
> also it oftens relieves the edema in my legs and the tension in my shoulders that I have from the stones. I also have a marked improvement in vision sharpness and contrast. What gives? Is my liver being detoxified, or what is happening? Any ideas would be appreciated.
The vision I would put down to possibly the EFA's in chlorella - especially if you are male. Do you take any EFA supplements (e.g. flax or fish oil)? If not you might consider one.
The rest of the relief sounds like detoxification. Chlorella is a great detoxifier, not just for the liver, but the whole body.
BTW Yaeyama chlorella is grown in pristine conditions in Japan - you can taste the goodness. One of my favourite supps of all-time.
