I'm starting with Red Clover because we have fields and fields of it in bloom right now. It's used to replenish nitrogen in the soil.
To brew it, I used two clean (and pesticide-free) large red clover blossoms. I added boiling water and steeped for 10 minutes. The aroma - well, it's like clover! The taste is lightly sweet and fresh and springy. See the link above for info on ways that Red Clover is believed to benefit your body.
My next herb will be "Thyme for Tea".
