Do you know what "good for all" means?
Well as it sounds:
something that may be beneficial for any condition one can think about.
There are quite a few herbs that fit this definition, but one which one surely can trust is : Triphala [a fruit mixture from India as tablet or capsule]
If there is a gastro-enterologist who does not know does herb......then it is sad.
But all doctors should use this herb on a regular base.
I will not some up here all the goods, but leave it as GOOD FOR ALL!
