I love rosemary -- it is easy to grow and wonderful to cook with. Plus, I just learned it is not only a powerful antioxidant, but also might have some specific anti-cancer properties as well. Its active ingredient carnosol has been shown to inhibit the growth of skin tumors.
This lovely Mediterranean herb can help fight colds and may help keep your memory in tact. It's quite fragrant and makes a tasty marinade for steak with just a little balsamic and soy sauce. You can also add a sprig to lemonade for a decidedly unique and surprising flavor.
