Effective tea for the purpose it says on the box - detoxifying. It did not cause me cramping or uncomfortableness. I did feel that it was successful in its purpose. Teabags are sorted inside the box with dividers depending on the time of day they should be taken, so it makes things easy. Quality is great and packaging is well-designed. Tea tastes good.
I just love those teas! There's something fun about expecting the little messages each bag contains. The taste is great and having different flavors for different timings of the day makes it more interesting to keep drinking. I use it daily for 14 days, then take a time and repeat whenever I feel the need to detox again
