coffee enema

Hi,

It's been awhile, since last posting here. My question is for my 77yr old mother. She's been using Sawilsons therapeutic coffee for several years. Only recently, like this past week, she's noted small black specks during her CE. She said the specks look like black pepper. She does not use black pepper. I was thinking perhaps 'strawberry seeds'? Is it possible for strawberry seeds to look black? She does not eat kiwi. These specks are much finer.. thank you, momo
