Shilajit

Does anyone know the benefits of taking Shilajit? I have read some basic information on the NET about the benefits etc but then these are from the suppliers of this ayurvedic medicaine and they are bound to dwell on the benefits.

Has anyone taken Shilajit? I have heard that it is a health tonic for daily use and can bring about vitality and assist in curing piles and some other ailments. Please talk to me about this if you are aware of the good and bad points. Any information on this would be appreciated.

Thanking you in anticipation.
