Depending on your father's age, you should be very careful with a persistent cough, and visit a doctor if his condition does not improve within another ten days or so. This is particularly important if he experiences any other symptoms, such as difficulty breathing, dizziness, and pain, or if the cough regularly interferes with his sleep. When a cough is particularly severe, prolonged coughing fits can cause complications such as fainting, vomiting, or a hernia, particularly in older patients.
A warm salt water gargle is one of the best remedies for a cough. It does not simply soothe the cough temporarily, but hastens the recovery process by getting rid of the bacteria from the throat. Another effective home remedy is warm milk with a pinch of turmeric powder. Your father should gargle with salt water several times a day, and drink a glass of this turmeric milk at night, about half an hour before going to bed. In the morning, before breakfast or even brushing his teeth, your father should take a tablespoon of honey mixed with a pinch of turmeric and a few drops of ginger juice. Some time in the middle of the day he can also drink a glass of warm water mixed with a tablespoon of honey and some lemon juice.
