2. Grow blue hydrangeas.

3. Exfoliate face.

Add coffee grounds to your favorite oil, then gently rub on your face. Keep a safe distance from your eyes. Leave on for added anti-inflammatory benefit. See the YouTube video below for more information on how to reduce inflammation under the eyes.

4. Curb headaches.

Since caffeine reduces the swelling of blood vessels, migraine sufferers are told to drink coffee to curb headaches. Not only can it reduce intensity, but it can also reduce frequency. Just make sure it is not decaf. Here?s a medical study on caffeine and migraines.

5. Keep pests out of your garden.

You may enjoy waking up to the smell of coffee, but pets (especially cats) don?t find the odor so great. Simply sprinkle some coffee grounds around where you don?t want pets to tread. If slugs and snails are your garden pests, sprinkle coffee grounds as a barrier. As the grounds dry it will create a barrier that slugs will not crawl over.
