Try Tea Tree Oil
For athlete's foot, reach for tea tree oil, an extract of the leaves of an Australian tree. It appears to have antiseptic properties and may work as well as or better than over-the-counter antifungal products. Apply a light coating of the oil to affected areas two to three times a day; continue for a week or two after symptoms disappear.
Research suggests that this Ayurvedic herb, also called holy basil, may help manage levels of the stress hormone cortisol, helping to boost your mood. Look for teas and supplements in health-food stores and follow package directions.
For dry skin, incorporate more avocados into your diet. They're rich in monounsaturated fat and vitamin E, both of which promote healthy skin. Try them on salads and sandwiches, and even in smoothies.
Keep Echinacea Close
If you feel a cold coming on, consider reaching for this age-old remedy. A 2007 meta-analysis showed that the herb can reduce cold symptoms. Aim for three grams daily in tincture or capsule form, starting at the first sign of symptoms.
Invest in a Neti Pot
Plagued with sinus problems? Rinse your nasal passages twice a day to flush out pollen and other irritants. Put saline solution (a 1/4 teaspoon salt and 1 cup warm water) in a plastic squirt bottle or a nasal irrigator, a spouted container that allows you to pour water directly into your nose. The solution should fill your nasal cavity and spill out the other nostril. Gently blow your nose afterward.
