How do you make chamomile tea from a plant?
First you must grow a chamomile plant (or purchase one). They normally bloom in spring, at which time you can cut off some blooms and allow them to dry in the sun. These can be stored in an airtight container, like a jar, until ready to use. Then you will take about a tsp. of the dried flowers and boil them in water for a few minutes. Strain into a cup and add sugar to taste.
