Both apples and apple cider vinegar can be used to fight off a headache. They help restore the acid-alkaline balance in the body. Furthermore, simply the smell of green apples can help reduce migraine headaches.
Alternative: Fill a large bowl with steaming hot water and add 3 to 4 tablespoons of apple cider vinegar to it. Hold a towel over your head and take in the steam for 10 to 15 minutes.
