Black tea is chock-full of astringent compounds called tannins that can help deflate and tighten the bags under your eyes. (Not to mention black tea is associated with a lower risk of type 2 diabetes.) Activate the tannins in a tea bag by dipping in a cup of hot water for several minutes. Cool in the fridge, then apply the damp bag as a compress to the closed eye for 10 minutes.
Mint has been used for hundreds of years as a health remedy. Peppermint oil might help with irritable bowel syndrome -- a long-term condition that can cause cramps, bloating, gas, diarrhea, and constipation -- and it may be good for headaches as well. More studies are needed to see how much it helps and why. People use the leaf for other conditions, too, but there’s very little evidence it helps with any of them.
