About 13 years ago I was taught how to do a coffee enema by my renowned holistic nurse. We used traditional coffee for the longest time until she discovered this product. Now I know she does research on everything and makes sure that it's absolutely the best before suggesting anything to me as a pre-med student or any of her patients. The product has been incredible and I've been using it ever since and recommending it to my patients! Going on about 5 years now and I am extremely pleased with this company, the service I get when I call, and the website to purchase the product. I wouldn't look any further if I were you as my people do the most research and when they find out there's a good product out there, they recommend it to their patients which is what I then do..
