Boil your water. I like to use a water cooker for that.
Place whole dried chamomile flowers in a new empty tea bag or a tea infuser.
Place tea bag/infuser in a large cup and pour hot water over that.
Steep for about 5 minutes. Take out tea bag/infuser.
Enjoy your hot tea with a sweetener of your choice (or non)
Option 2 - boil & strain
Bring a small pot with water to boil over the stovetop.
Add the dried chamomile flower buds to the cooking water.
Turn of the heat or take the pot from the stove.
Allow the flowers to steep for 5 minutes.
Take the infused herbal tea through a fine sieve and pour your ready and hot tea into a cup.
Sweeten your tea if you like and serve hot.

Notes
Dried chamomile flowers have small tiny yellow pieces in the core which detach in the hot water. Use a fine sieve/tea bag/infuser if possible or else you will have these tiny pieces in your tea. The image with the flowers in the tea was just show. :P
