Synopsis

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

Echinacea angustifolia has a long history of use in North American traditional medicine, especially by Indigenous peoples, for the treatment and prevention of infections, such as colds, respiratory infections, and wounds. In more recent decades, this use has been investigated in scientific studies. Research has focused largely on Echinacea purpurea, but some studies include E. angustifolia. Laboratory studies have demonstrated that Echinacea extracts can modulate immune function, including increasing phagocytosis and stimulating cytokine production. Some randomized controlled trials have suggested modest benefits in reducing the duration or severity of upper respiratory tract infections, but results are inconsistent and often limited by methodological flaws, such as small sample sizes, variable preparations, and lack of standardization. Systematic reviews and meta-analyses generally conclude that Echinacea preparations may have a small effect in preventing or treating the common cold, but the overall quality of evidence is low to moderate, and efficacy specifically for E. angustifolia is less well established than for E. purpurea. There is insufficient evidence to recommend Echinacea for treatment of more serious infections. Overall, while some scientific evidence exists supporting a potential role in mild infections, particularly upper respiratory tract infections, the strength and consistency of the evidence is limited.
