Bronchial asthma is a serious global health problem. The latest estimation of WHO indicates that there were 417,918 deaths due to asthma at global level. Among India’s 1.31 billion people, about 6% of children and 2% of adult have asthma. It is a chronic disease characterized by episodes of acute bronchial constriction causing shortness of breath, cough, chest tightness, and rapid respiration and wheezing. Asthma is described with different names in Unani literature as Rabu, Zeeq un Nafas, and Dama. In Unani literature, asthma is caused by thick Phlegm which is adhered on the bronchial mucosa to develop narrowing of lumen. In Unani perspective, it is characterized by paroxysm of breathlessness with or without cough, cold and fever, sometimes sweating, low body temperature and increased respiratory rate. As we all know, medicinal plants are always a constant source of medicaments for the variety of disease; Unani scholars have also found effective treatment for the bronchial asthma with plants. Since asthma is explained as a disease with cold and moist temperament, the management of asthma is done by hot and dry drugs (ilaj bil zid). This review paper is an attempt to give knowledge about some single drugs used in Unani medicine to treat bronchial asthma.
