I've been sick for over a week now, and I've been drinking all kinds of tea non stop. My favorite 'tea' to drink when I'm under the weather is ginger with a large spoon of honey and a good squeeze of lemon. It tastes good, and all three ingredients help fight that cold or flu. The ginger and honey help boost the immune system, and the lemon has lots of vitamin C.
To make my ginger tea I take an inch or so of ginger, cut into small pieces, and boil it with water for 15-20 minutes. Or you can grate the ginger and pour boiling water over it and let it steep for about 20 minutes. After the tea has steeped, just add honey to taste, and squeeze in a large lemon wedge (or as much as you like). Through a bit of web searching, I discovered adding the zest of the lemon to the boiling water is also beneficial. You'll just want to strain the water after cooking. But don't add the lemon juice or honey until you turn the heat off. You don't want to cook out the nutrients.
What is your go-to tea when you are under the weather?
