I've been drinking rosemary tea for the last few weeks before going to sleep. I had read about some of the health benefits and prefer it to drinking wine at night. Apparently rosemary is loaded with vitamins (A/B/C/D/E/K), good for the brain and aids digestion. I normally cut several inches of fresh plant and soak steep it in 176F water for 5-10 minutes. There is no bitterness and it is extremely fragrant. I've tried additional variations such as rosemary and thyme and a third combo using honey as a sweetener and cooling down the rosemary as a ice tea. They are all very nice.
