It is prepared by mixing the seeds in water with the volatile oils blending well with the water.

You can dry fennel seeds by laying them flat and sun-soaking for three days or by microwaving them in increments of 30 seconds. Then, crush the dried seeds (1 to 2 tablespoons) using a mortar and pestle or you can simply crush them with the back of a spoon to release the flavor. Place the crushed seeds in a mug. Pour a cupful of very hot water (not boiling), cover, and steep for 8 to 10 minutes. Don’t forget that the longer you steep the tea, the stronger the brew will taste. For an added experience, you can use a little bit of honey to the tea. Finally, strain and enjoy the tea!
