blue lotus tea preparations..

okay, someone mailed me an oz bag and ive tried smoking maybe a bit more than a gram of crushed dried leaves in a bong, and i got nothing. I also made tea with about 4 tablespoons and let it steep in the water after I boiled it, nothing too except for a bit of light headedness. I asked my friend about this but she hasnt gotten back to me, the stuff came from vancouver but I dont know where she got it, it looks decent. help me.
how do I make decent tea, with how much, steeping time, etc.
and you need to smoke a few grams (5+?) i found out which is heavy on my lungs so I'd rather make the tea.
