At this point it is hard to give a full review of this tea because I use it only occasionally, and that is why I gave it only 4 stars. When I have finished the box, I may be able to give a better rating. Like other instant Ginseng teas I have taken, it has a mild flavor, and can be over stimulating if used too often. If you are new to using ginseng, it should not be taken in combination with caffeinated products, or taken when you have a cold / flu. Hope this is helpful.
