Synopsis

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

Oldenlandia, particularly Oldenlandia diffusa (also known as Hedyotis diffusa), has a long history of use in traditional Chinese medicine (TCM) for various ailments, including fever and infections, which sometimes encompass symptoms of the common cold. In TCM, Oldenlandia is considered a "heat-clearing" and "detoxifying" herb, and is often prescribed in formulas intended to address conditions believed to be caused by "heat" or inflammation, including respiratory infections. However, there is limited direct historical documentation specifically linking Oldenlandia to cold prevention; its use is more broadly indicated for general "febrile diseases," which may overlap with colds. Scientific evidence supporting Oldenlandia for cold prevention is very limited. Some laboratory studies have reported immunomodulatory and anti-inflammatory effects of Oldenlandia extracts, but these studies are preliminary, mostly in vitro or in animal models, and do not directly address common cold pathogens or prevention in humans. There are no robust clinical trials confirming its efficacy in preventing colds. Thus, while Oldenlandia's use has a traditional basis related to infection and fever, scientific validation for its specific role in cold prevention is lacking, warranting a low evidence rating.
