Yes, but it depends on whether the body can accept it. I used to lose weight and drink it for a while, but it was almost a bit empty as herbal tea, mainly because it was a bit like diarrhea to need to go to the toilet physically after drinking it. Long-term drinking is not recommended. If it is not constipation, it will affect the stomach. Controlling diet, doing more exercise and losing weight can be better and more effective.
