ASTHMA AND HERBAL DRUGSAbstract
Asthma is disease of the human respiratory system in which the airways constrict and become narrow, often in response to a “trigger” such as exposure to an allergen, cold air, exercise or emotional stress. Due to rapid industrialization and urbanization, asthma prevalence is predicted to increase more rapidly in the coming years. Despite the availability of a wide range of drugs for the treatment of asthma, the relief offered by them is mainly symptomatic and short lived. Moreover the side effects of these drugs are also quite disturbing. Medicinal plants have been known for millennia and are highly esteemed all over the world as a rich source of therapeutic agents for the prevention of diseases and ailments. The importance of herbal medicine in the treatment of asthma is indisputable. Four of the five classes of drugs currently used to treat asthma namely; β2-agonists, anticholinergics, methylxanthines and cromones have origins in herbal treatments going back at least 5000 years. In the present article an attempt has been made to review antiasthmatic medicinal plants with their active chemical constituent and possible mechanism of action.
