Interesting article about the benefits of Cardamom, I like this in tea. I tried black tea with crushed cardamom seeds a few years ago that a lady who runs our corner shop gave me and it was lovely.
I bought the seed pods to make my own cardamom tea with but it was fiddly opening the seed pods so now I buy the powdered seeds. Just a pinch is added to a cup of tea and it is so soothing.

A little more information here too, be careful if you are taking blood thinning medication or have gallbladder stones. Golden rule is check with your doctor before trying this herbal tea.
