As the name suggests, cough variant asthma is a type of asthma that causes a dry, non-productive and constant cough as its primary symptom. It is commonly seen in children, or during early childhood. It may later develop into a typical Asthma condition with wheezing. Once triggered, an episode of cough variant asthma can last for 6-8 weeks. Homeopathic medicine for cough variant asthma can be used with conventional treatment to help reduce the severity of symptoms and treat the chronic condition.
