Micro, de,
Very interesting discussion on vinegar.
I have a moisturizer on my fan assembly from the heat pump (actually, I stopped using it). The filter on that thing takes particulate matter out of the water that looks like clay on the filter. Our water is crystal clear and it's disturbing that there is so much of this stuff, whatever it is, in it. We're drinking it. But where I'm going is the maintenance folks said to use vinegar to eliminate this stuff from the mechanism that sits in the water, which also gets gummed up with it. It dissolves it away.
So, I'm wondering if the vinegar performs a similar function in the body, dissolving your friend's sand in his gall bladder and maybe even cleaning out the blood vessels a bit, since cholesterol is positively impacted. Wouldn't it be something if high cholesterol resulted from particulate matter in water congealing with cholesterol in the blood vessels or something.
I'm the furthest person from an expert on this, of course, but I have found that what seems to be common sense sometimes applies.
