Synopsis

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

Vietnamese sophora (Sophora flavescens, also known as Ku Shen) has a long history of use in traditional East Asian medicine, including Vietnamese, Chinese, and Japanese herbal practices. While its primary historical uses have focused on the treatment of skin conditions, fever, and gastrointestinal issues, there are traditional formulations in which Sophora flavescens is included as a component to address respiratory complaints, such as cough and bronchial congestion. The traditional rationale is based on its purported “heat-clearing” and “phlegm-resolving” properties, as described in classical texts of Chinese medicine.

However, direct scientific evidence supporting the use of Vietnamese sophora specifically for bronchial congestion is limited. Some pharmacological studies have demonstrated anti-inflammatory and antimicrobial activity of its alkaloids (notably matrine and oxymatrine), which could theoretically be beneficial in respiratory tract infections or congestion. Still, these studies are preliminary, mostly in vitro or in animal models, and do not directly address clinical efficacy in humans for bronchial congestion. Therefore, the use of Vietnamese sophora for this condition is based more on tradition than on robust scientific validation, and the overall quality of evidence is low (rated 2/5).
