There are many sites on the web that give you great recipes for making herbal teas.  Some of these recipes are healthy and some just taste great.  You can study all of the herbs and their healthy properties, but to make them mix well and taste good, is a tricky process.  Here is a link to some great recipes: http://coffeetea.about.com/od/herbaltearecipes/Herbal_Tea_Recipes.htm.  The Tropical Herb Tea tastes amazing.  The mango and papaya are earthy and delicious as their flavor blends with the lemongrass and mint.  It’s yummy, but you have to let it steep in the refrigerator overnight.  This link is all about healthy teas, and finding some of them may be a challenge.  A good organic market should have the hard to find herbs. http://www.glenbrookfarm.com/herbs/13000tearec.html.  This tea is so good http://www.foodnetwork.com/food/recipes/recipe/0,,FOOD_9936_28596,00.html?rsrc=like, and other teas on foodnetwork.com are very good too!
