Hi thanks for contacting HCM.. Cough is reflex to excret secretions and foreign material.... If you are smoker then by chronic irritation cough also can occur... So avoid smoking if habit ... Second if you have repeated allergic infection like rhinitis then cough also can be there.... Try below remedy for cough.... Take one glass milk .Add half tsp turmeric powder in it ..then add half tsp black pepper powder and finally add one tsp honey ..mix it and drink daily... Hot water drinking done ... Steam inhalation once daily ... If cough for more then three week then chest x ray done to rule out bronchitis. .. Take care ...
