There is no harm, just a substitute plant drink, you can try it, because its weight loss effect is still very effective, and of course it varies from person to person.
If you really want to lose weight, I suggest you don't trust this substitute tea. Countries often don't recognize it. If you are a food lover, if you are a short man in action, if you are a person who is afraid of trouble but just needs to lose weight, then I think it is often the best for you. A cup a day can often simply reduce weight, control your weight and keep you beautiful.
