Role of Medicinal Plants in Asthma Treatment: Insights from Clinical Evidence

This review is about the effects of medicinal herbs in the treatment of asthma. Asthma is characterized by bronchospasm resulting in breathlessness (dyspnea) due to the high concentration of various inflammatory cells, which include eosinophils, mast cells, lymphocytes, and others, which cause constriction of the smooth muscle of the bronchus. Approximately 300 mL people suffer from asthma, in which they experience wheezing, shortness of breath, and coughing, particularly prevalent at night and early in the morning. Asthma has two types: Type 2 high and type 2 low. Both have different inflammatory mediators that cause inflammation of the mucous membrane. Many clinical trials show scientific evidence of the effects of phytomedicine in treating asthma, which are listed in this article.
