this is not for you to get 'high' off of. it's a shamanistic herb that has been used for religious/spiritual purposes for hundreds of years.
if you aren't afraid of seeing what seems to be other dimensions of unexplainable origin, then you should be fine.
just remember, you will come back to reality as you've always known it.
as ghengiskhan said, this is for exploring your mind. exploring beyond your reality.
