Four natural foods work better for many sore throats, than typical cough syrups. Most professional singers probably know three of these ingredients and should know all four.
Drink one to four ounces of raw honey. Honey is a germ killer. It can cure some sore throats and eliminate laryngitis instantly. (If you'd rather pay a doctor to recommend an expensive cough syrup, before you try this remedy, write stupid on your shirt and go look in the mirror).
Step2
Add salt to a slice of lemon and eat it.
Step3
Get a bottle of peppermint oil from a health food store or drug store. (If neither has it on the shelf in your area, ask them to order a bottle for you). Add two or three drops to your tongue hourly or as needed.
Tips & Warnings
Many cough syrups are cough suppressants. They are designed to alter your body' s natural healing process by stopping you from coughing. Your body is supposed to cough excessive fluid out of your lungs for your health' s sake. If your lungs fill up with body fluid, will you not have pneumonia?
For extreme cases only, when too much coughing might damage your throat, consider cough suppressants or seeing a doctor.
