Synopsis

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

Sophora flavescens (commonly known as Ku Shen) has a long history of use in traditional Chinese medicine (TCM), where it is employed for various conditions, including colds, fever, and respiratory infections. The justification for its use in treating or supporting colds is primarily based on traditional use rather than robust scientific validation. In TCM, Sophora flavescens is considered to have "heat-clearing" and "detoxifying" properties, and is often included in polyherbal formulas for symptoms associated with colds, such as sore throat, fever, and cough.

Some laboratory studies have found that certain alkaloids and flavonoids isolated from Sophora flavescens demonstrate antiviral activity in vitro, particularly against viruses such as influenza and hepatitis. However, these results have not been consistently replicated in human clinical trials, and there is a lack of well-designed studies specifically evaluating its efficacy for common colds or related viral infections in humans.

Overall, while there is a traditional basis for using Sophora flavescens for colds, the scientific evidence remains limited and preliminary. The current use is thus best characterized as traditional, with a low-to-moderate level of supporting evidence.
