My friend took it before and didn't insist on it, so it is difficult to evaluate whether it is effective or not. It's just that he said that every time he took this medicine, the stool the next day was not solid, but soft. It is possible that all the grease is in it, but I always feel that it is not completely discharged. It was purely her personal feeling that there was no scientific basis, and then she stopped eating. Please refer to it immediately.
