More than 22 million Americans suffer from the chronic inflammatory disease asthma and the number is steadily growing, especially among children. Asthma symptoms include airflow obstruction, chest tightness and shortness of breath, wheezing and coughing. Severe asthma attacks can be fatal. Mainstream medicine treats asthma symptoms with drugs and medical inhalers, some of which have side effects so dangerous that class actions suits have been filed against the makers. Nature offers a number of safer options for relieving and preventing asthma as well as healing and supporting the lungs.
