constipation
"I used to use this for years.  But recently I have been constipated due to my medications.  I bought a bottle and when I used it (according to instructions 2 tbsp for an adult) it made me very ill.  I was nauseated and I was vomiting.  I thought it was just a bad bottle, so I went and bought another one and the same thing happened when I used it.  I don't know if they changed something with the ingredients but this is the first time this stuff made me sick."
