No matter what you've heard or how badly you want relief, talk with your doctor or pharmacist before trying any home remedy. This is even more important if you take prescription or over-the-counter medications, because some can affect how drugs work. And keep in mind that many don’t have any research to back them up.

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.

Honey is a natural sweetener may work just as well for a cough as over-the-counter medicines. That could be especially helpful for children who aren’t old enough to take those. But don’t give it to an infant or a toddler younger than 1. There’s a small risk of a rare but serious kind of food poisoning that could be dangerous for them. And while you may have heard that “local” honey can help with allergies, studies don’t back that up.
