Look into oregano oil for respiratory issues and especially for asthma. My son had asthma years ago. We changed his diet (took him off of wheat and dairy) and started him on oregano oil, and from those changes alone he never had another asthma attack again. We still stick with the diet and only give oregano oil now if he has a cold, but he breathes normal at night even with a cold now. I just do it because it helps kick the cold out of his system more quickly with the oregano oil. Good luck.
