I know a really good quick remedy for cough. I learned this from my friend. Apply Vicks rub on the bottom of feet and wear socks. Keep the feet and body warm. It relieves coughing in about five minutes. I tried it on my daughter and it really worked. She couldn't sleep because she was coughing so much. This method stopped the coughing and she went to sleep. It's not a permanent cough treatment, but it definitely provides some quick relief. Try it!
