I have tried several teas of this nature and have yet to find one that lives up to its claims. I am sure they must benefit a # of people as they seem to sell well. Who knows, maybe I will give it a try. I am considering refraining from backing any further kickstater projects until I receive at least one of the ten things I have supported, all which were succesfully funded. It seems everyone of these projects has suffered delays for one reason or another.
