Mother Earth Living has a great list of uses for mint. Just be sure to plant the herb in a separate container, away from other herbs, as it can quickly take over your garden. Here’s what they have to say:
A true botanical wonder, mint is a breeze to care for, and its pleasing aroma makes it a welcome addition to the garden. The best part about this easy-to-grow herb is its usefulness. Mint makes a delicious addition to meals, a healthful tea, a fragrant potpourri and an insect-deterring spray. This sweet-smelling plant also has soothing and anesthetic properties that make it a great fit for homemade body-care products. To grow mint, get a cutting from a friend or purchase a starter plant at a nursery. (Mint doesn’t reproduce true from seed.) Mint can actually be too easy to grow—it sometimes takes over the garden—so give this attractive ground cover plenty of room to spread, or plant it in a container.
1. All aBuzz: Growing mint will keep your yard and garden buzzing with beneficial insects. Mint is rich in nectar and pollen, and its small flower clusters keep these sweet treats easily accessible for helpful bugs such as honeybees and hoverflies.
2. Bug Off: While it attracts “good bugs,” mint also deters “bad bugs.” Repel ants and flies by growing pennyroyal mint right outside your door, or spray diluted peppermint essential oil (10 parts water to one part oil) around doorways and windows.
3. Flea Free: Keep pets free of bothersome fleas with this homemade repellent: Bundle 2 parts fresh spearmint, 1 part fresh thyme and 1 part fresh wormwood, and tuck it inside a small pillow. Place the pillow near your pet’s bed or another favorite resting place.
4. Room Refresher: Keep your home smelling fresh by adding a few drops of mint essential oil to your favorite homemade or unscented store-bought cleaner. Try this simple floor cleaning solution, good for wood, concrete or tile floors: Dilute a cup of white vinegar in a gallon of water and add 3 to 5 drops of mint essential oil.
5. Beverage Booster: Mint is refreshing in iced beverages. Add sprigs of fresh mint to a pitcher of water or plain iced tea, let it sit for 30 minutes or more, and serve it over ice. If you enjoy cocktails, mix fresh mint into homemade juleps or mojitos.
6. Veggie Revamp: Enjoy an interesting twist on a vegetable medley by adding fresh or dried chopped mint to peas, green beans, carrots or cauliflower during their last two minutes of cooking.
7. Divine Desserts: Mix 2 tablespoons finely chopped fresh mint leaves into chocolate chip cookie dough and bake as usual for wonderfully minty treats.
8. Breath Saver: You don’t have to rely on mint gum or candies to freshen your breath. A sprig of your favorite fresh mint variety will get rid of bad breath just as well. Simply pluck and chew.
9. Tummy Tamer: Peppermint tea is an excellent way to ease an upset stomach. Peppermint helps calm the digestive tract and alleviate indigestion, intestinal gas and abdominal cramping.
10. Hiccup Help: Try this homemade concoction to help soothe the diaphragm irritation that can cause hiccups: Pour a glass of lukewarm water, then add a couple squeezes of fresh lemon juice, a pinch of salt and a few mint leaves.
11. Steam Clean: A peppermint steam can help clear sinuses and congestion and fight infection. Bring a pot of water to boil, turn off the heat, add a few drops of peppermint essential oil and lean over the pot, draping a towel over your head. Breathe in the minty steam. Mint steams also act as a cleansing and stimulating facial.
12. Nausea Nix: Peppermint essential oil can boost your mood and reduce feelings of nausea. Simply add a couple drops to a clean handkerchief and breathe in.
13. Headache Healer: Apply a few drops of peppermint essential oil to your temple to relieve migraines, as compounds in peppermint oil are known to calm muscle spasms. You can also make a simple compress to get rid of tension headaches: Pour 3 cups hot water over 3 peppermint tea bags. Steep, covered for 5 to 7 minutes; remove tea bags and add ice. To use, dip wash cloth into cold tea and apply to forehead.
14. Fresh Feet: Mint soothes aching feet thanks to the pain-relieving properties in menthol, a compound in mint. Menthol also triggers a cooling sensation, perfect for foot scrubs. Try this one: Combine 1 cup sea salt, 1⁄3 cup olive oil and 6 drops peppermint essential oil. Scrub feet and rinse.
15. Sunburn Soother: Menthol cools and refreshes the skin, making mint a handy herb to keep around in the summer. Use it to ease sunburn pain by making a strong peppermint tea and refrigerating the mixture for several hours. To use, gently apply to the burned area with cotton pads.
