Is the yeast plum sold by Wang Meng, the big head sister, really useful?

Really useless! I bought five boxes and gave one as a gift. I run to the toilet after eating every day, and my appetite hurts. This plum hurts my stomach a little. Besides, when I finished five boxes and stopped, I didn't take a shit for a week! I feel horrible. When I went to the hospital, the doctor said that this kind of plum can't be eaten all the time, and it is dependent. If I eat for a long time, my stomach will be damaged! ! I lost 3 pounds when eating, but I will gain weight when I stop!
