We have a section called the peoples pharmacy and the weekend a writer asked about a product and... "potassium nitrate found in Sensitive toothpaste can help with Asthma and Allergies,"
So might be worth giving Sensitive teeth toothpaste a try, just make sure it has potassium nitrate in it.
Also, for cough they recommended Vicks put on the feet at night, might be of help.
Just thought someone here might benefit from this info...
many well wishes to all.
