Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Ophiopogon root (Ophiopogon japonicus, known as Mai Men Dong in Traditional Chinese Medicine, TCM) is traditionally used to address respiratory conditions, including bronchial congestion. In TCM, Mai Men Dong is classified as a yin-nourishing herb with moistening properties, often prescribed to treat dry cough, throat irritation, and conditions characterized by thick or sticky sputum. These uses are rooted in centuries of practice, where the herb is thought to clear lung heat and moisten dryness, thus relieving symptoms of congestion in the respiratory tract. Classic TCM formulas, such as Mai Men Dong Tang, include this root for its purported benefits in treating cough and lung dryness. Scientific validation for these traditional claims is limited, but some preclinical studies suggest Ophiopogon root may possess anti-inflammatory, expectorant, and immunomodulatory effects. For example, animal studies have shown that extracts of Ophiopogon japonicus can reduce airway inflammation and improve mucociliary clearance. However, these studies are preliminary, and robust clinical trials in humans for bronchial congestion specifically are lacking. Thus, while it is widely used in traditional practice and supported by some laboratory evidence, the overall scientific support remains modest. In summary, the use of Ophiopogon root for bronchial congestion primarily relies on traditional usage, with a moderate, but not strong, level of supporting evidence.
