Hello. There are many reasons for dry cough. It can be due to allergic reaction, which has to be treated with anti allergens like turmeric. It can also be due to a reflex mechanism like frequent ear cleaning, which stimulates the nerves inside the ear and result in cough. In such case, the ear cleaning frequency should be reduced to once in a week. It can also be due to smoke and dust, which are to be avoided as far as possible. Use 1 teaspoon melted ghee in half a glass hot water, drink it sip by sip thrice a day.
