To use it in a tablespoon dose each day for multiple days is unusual advice. As you mentioned its more common because of the gastric action to do it far less often, unless, one's GI system has been impacted by lifestyle choice or physical disability and one is very ill, and evan then most would advise to do it as a pack.
I have a friend who uses one half of a teaspoon daily for chronic constipation without any problem. They are disabled.
Using CO in the heat pack protocol is theraputic for a range of issues, liver and intestinal related especially, tho it has evan far reaching affects too.
