[YEA] Cutting down on sodium and increasing magnesium, cured my cough. I cut down on the amount of salt I was using. I had also been taking sodium ascorbate (vitamin C)~175mgs 5 or 6 times daily. I switched to magnesium ascorbate. The magnesium seems to help relax the muscles. I had been having an unrelenting dry cough that was causing sore stomach muscles. Switching to magnesium ascorbate and cutting out the sodium helped to loosen the mucous but didn't produce a runny nose. I had to take calcium along with the magnesium to prevent muscle cramping. Just eating milk products like cheese seems to be good enough.
I also started taking N-acetyl cysteine to help get rid of the wheezing. I took 1/2 a tablet (300 mgs) twice a day.
I think asthma could be helped by this method.
