We have used this brand in the store for 3 years. We used to use coffee enema, but customers didn't pat the stool. And after a long time, customers don't defecate and have to rely on it. Arabella's formula is really good. After using it, customers can hold back, do not feel abdominal pain, and excrete a lot of black stool. This will vary from person to person. Some people have to do it for 3-5 times before they can take pictures of severe black stool. This is a good project.
