Have a headache/migraine? Submerge your feet and hands in hot/warm water and put a bag of frozen peas at the base of your skull. The heat on your extremities pulls the blood from your head relieving some/all of your headache.
Use Vicks Vapor Rub and socks. Even the worst cough can be stopped within 5-15 minutes, and lasts hours. Just apply the vapor rub generously to the bottom of your (or child's) feet, and cover with socks. works 100% of the time, and has been proven to work better than prescription drugs!
