Here are some simple remedies for a few common ailments, courtesy of Woman's Day magazine. * Puffy eyes. Apply a cotton ball dipped in ice-cold whole milk for 10 minutes. This works because the high-fat content in the milk provides a moisturizing treatment for the delicate skin around the eyes and reduces puffiness. * To treat acne: Apply a dab of fluoride toothpaste to the blemish and cover it with a band-aid overnight. Why? Well, fluoride fights the bacteria that cause acne, and the calcium carbonate in the toothpaste helps dry out pimples. But keep in mind - this remedy won't work for everyone. People with sensitive skin can sometimes make their acne WORSE by using toothpaste. So if you have sensitive skin - stay away from the Aquafresh. * If you have a stuffy nose. Drink one teaspoon of freshly grated horseradish mixed with one-fourth cup lemon juice. The horseradish produces quick mucus release, and the lemon juice helps it go down easier. Just don't put the mixture directly in the nose because it'll cause blisters to form. * Foot odor. Dissolve two Alka-Seltzer tablets in a quart of warm water and soak your feet for 15 minutes twice a week. This works because the baking soda in Alka-Seltzer increases the acid level on your feet, which inhibits the growth of odor-causing bacteria. If you're allergic to aspirin - a key ingredient in the fizzy tablets - try sprinkling baking soda in your shoes to absorb any odors.
