For unproductive dry cough Put about two beer bottles of water in a pan, make the water boil, add to it two spoonfuls of edible oil, preferably peanut oil, and two or three spoonfuls of white sugar. Beat thoroughly a hen's egg, mix it with the water, and heat the mixture until it boils. Drink a glass of this mixture reheated to a proper temperature in the morning and evening for three days on end. The dry cough will surely be cured.
