Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Ephedra, also known as Ma Huang, has a long history of use in traditional Chinese medicine for respiratory conditions such as wheezing, asthma, and bronchitis. The active compounds in Ephedra, particularly ephedrine and pseudoephedrine, are sympathomimetic alkaloids that act as bronchodilators. These compounds stimulate adrenergic receptors, leading to relaxation of bronchial smooth muscle and resulting in improved airflow and relief of wheezing symptoms. Scientific validation for Ephedra's role in treating wheezing comes from both historical clinical use and pharmacological studies. Ephedrine was one of the earliest effective oral bronchodilators used in Western medicine for asthma and related respiratory symptoms before the development of modern beta-agonists like albuterol. Clinical trials from the mid-20th century demonstrated that ephedrine could improve airway function in asthmatic patients, though with less specificity and greater side effects compared to newer medications. However, the use of Ephedra and its alkaloids has declined due to safety concerns, particularly cardiovascular and central nervous system side effects, and the availability of safer, more effective alternatives. Nevertheless, the evidence supporting its bronchodilatory effects and historical clinical application justifies a moderate evidence rating. Regulatory authorities in many countries have restricted or banned Ephedra-containing supplements due to risks, but its scientific basis for bronchodilation and relief of wheezing is well-documented.
