Any homemade [or otherwise] remedies to help ease the dry/non-productive cough ociated w/ Acute Laryngitis?

Zinc lozenges have been proven to help get rid of viruses. Zinc tablets won't work as well because the mineral has to coat your throat. I also like to use Propolis in a honey base. Get the paste type and suck on a spoonful until it dissolves. It is a natural antibiotic and the honey soothes the throat. Being a Bee product it also gives an energy boost.
