If you have constipation, you can try it, but pay attention to the amount. If your constipation is not serious (2 days 1 time), just take 1 tablet for the first time before going to bed. 2 tablets may always make you diarrhea. If you have serious constipation, take 2 ~ directly for the first time. Almost all day, you will have irregular bowel movements, and it is not convenient to go to the toilet. Your stomach will really kill you, all kinds of stomachaches and cold sweats.
