Any cough syrup with DM, a cough suppressant. If you are on any meds, ask the pharmacist first.

If you don't want to use a DM syrup, there are lozenges too.

However - you won't have to use much of the DM syrup...just make sure you don't eat or drink right after taking a teaspoonful, or it'll wash away.

I understand your wanting natural remedies...but sometimes, you have to bring in the big guns, for a short time.

After all - earthquakes and hurricanes are "natural", too!
