In July A Good Friend Of Mine Used The Nulytely

In July a good friend of mine used the Nulytely product to prep for a colonoscomy. It burned her from her mouth to her rectum. Now her colon is partially paralyzed and she can barely eat. She is down to 93 pounds and looks like she just left a concentration camp. The doctor disavows everything. She is 74 years old and just looks awful. What on earth caused this reaction.
