Asthma is one of the most common chronic diseases worldwide. To treat this widespread disease there is a high prevalence of usage of herbal medicine. The use of plants is as old as humankind and it has been steadily increasing over the past 10 years. Plant-based remedies are now one of the most popular complementary treatments. Herbal supplements are receiving increasing exposure through media, including the Internet, in lay journals and more recently in the scientific press. Interest in herbal medicine has been facilitated by multiple factors, including the perception that pharmaceutical medications are expensive, overprescribed and may often be dangerous. Alternatively, herbal medicine is often perceived as being "natural" and therefore is considered safe. However, the scientific literature supporting the efficacy of herbal therapies is incomplete. There are few well-controlled studies that support the efficacy of herbal remedies in the treatment and clinical improvement of patients with asthma. Available scientific evidence has not yet confirmed the validity of their popular role in the treatment of asthma. The present review evaluates herbs and their efficacy in asthma to provide a balanced and objective view for the reader seeking information on herbal therapy
