Passion iced tea bags and boiling water makes the best hibiscus iced tea. Just let it cool down before you pour it over ice. You can also blend it with zen in a 1:2 or 1:3 ratio of passion to zen. I love it because it's really acidic and it tastes tropical. Very refreshing on a hot day. Just don't brush your teeth for a while after drinking it, as the acidity will soften the outer surface of your enamel. This is true for all acidic foodstuffs.
