The incidence of asthma has been steadily increasing in industrialised countries in the past decades. In spite of the introduction of several new drugs for the treatment of asthma, it is still by far the most common chronic debilitating disease in childhood. Some researchers are investigating the possibility that long-term use of some anti-asthma drugs such as bronchodilators may be  detrimental. Children do become addicted to inhalers, and this does pose a problem during treatment.

For Chinese Medicine, Asthma attack is considered as the acute or excess phase of the illness where urgency of treating the symptoms may outweigh that of the cause. Herbal treatment of asthma attack is quite effective. However, severe asthma patients who have been on long-term steroids treatment may not respond as quickly or as effectively to herbal treatment.
