Echinacea, particularly species like Echinacea purpurea and Echinacea angustifolia, has a long history of traditional use among Native American peoples and in European herbal medicine as a remedy for infections and as a general immune system booster. Before the advent of modern antibiotics, Echinacea was commonly used in the United States and Europe to support the body's ability to fight off various infections, including respiratory tract infections and wounds. The rationale was based on observational and anecdotal evidence that Echinacea could stimulate the immune system and potentially help the body clear infections more effectively.

In modern times, there have been numerous studies evaluating Echinacea's efficacy for preventing or treating infections, most notably the common cold. Some studies suggest mild immune-modulating effects, such as increased phagocytic activity or cytokine production, but results are inconsistent and generally do not approach the efficacy of antibiotics for bacterial infections. Echinacea has not been shown to possess direct antibacterial effects comparable to antibiotics, and it is not considered a true alternative for treating bacterial infections. While it remains popular in herbal medicine as an "immune support" agent, current scientific evidence does not robustly support its use as a substitute for antibiotic therapy. Its use in this context is justified primarily by tradition rather than strong scientific validation.
