My kid 3 years old is going to pre school since October. Since then she is having episodes of  cough and cold which are on and off. Whenever weather changes i.e. become cloudy or cold her symptoms start with dry cough. There is no fever. My doctor has suggested to use Himalaya bresol for couple of months after seeing her condition. In her case is Himalaya Septilin better to use than Himalaya Bresol? What is the difference between these two syrups?
