It's always when you have the least time for it that a crippling headache kicks in. Call it nature's way of telling you to slow down already. Since you can't always (Read: ever) tell your boss to shove his unrealistic deadlines, ginger tea may help. According to Dr. Oz (my doctor of choice when I'm obsessively Googling my symptoms), ginger tea is an effective anti-inflammatory agent. The spicy root helps to block prostaglandin synthesis (which causes the swelling you get when you have a headache). Rather than gnawing on a chunk of gingerroot, slice some up and boil in hot water for a homemade herbal tea, or take the easy route and pick up some ready-to-brew tea bags. Ginger tea can also help with nausea -- headache-inducing or otherwise.

It's 3 p.m. and aside from watching the clock tick by, all you can think about is what snacks you can snag to make the day go by faster. I readily admit to sneaking a bag of chips or a sweet treat rather than an apple when I hit my midday lull. Instead of raiding the refrigerator, take a break from your computer to brew a cup of green tea. Plant chemicals called EGCG can magically make you feel full, so you'll feel like you just ate a pan of brownies (minus the guilt). Bonus: Green tea is also shown to give you energy, so you won't get the crash you get from carb- or sugar-laden afternoon snacks -- and it helps keep your body from storing fat. So long, love handles!

Remember all that anxiety I mentioned? Well, let's just say those bouts of stress do not make for restful nights. Enter valerian root, the sandman of tea. Valerian root has been used for a variety of health issues including muscle pain, anxiety and menopausal hot flashes, but it's most common use is as a natural sleep aid. Valerian acts as a mild sedative, helping you sleep better and uninterrupted.

For those days you forget your breath mints (or forgot to brush your teeth), a cup of polyphenol-rich black tea can save you from embarrassing bad breath. The antioxidants can stop plaque and other buildup from adhering to your teeth. Plus, if you're game to swish and spit your tea (not as relaxing as simply enjoying a cup), a study by Pace University found that rinsing with black tea can inhibit bacteria growth and destroy the acids that cause tooth decay. Just remember that tea, like coffee, can stain your pearly whites, so don't even think of using it as a toothpaste replacement.

If sugar cravings are your biggest vice, skip the crash (and the calories) and opt for a cup of licorice root tea, which is naturally sweet and has only two calories per cup. Licorice root is actually 50 times sweeter than sugar, so although it doesn't seem like it could take the place of a big bowl of ice cream, your sweet tooth will quit its fussing. However, like anything else, drink licorice tea in moderation. The University of Maryland Medical Center warns over 20 grams of licorice root a day can lead to increased blood pressure and other ailments.
