• Conjunctivitis. It is unclear if topical eyebright eye drops are beneficial in patients with conjunctivitis. Details: A small observational study shows that applying one drop of eyebright eye drops (WALA Heilmittel GmbH, Eck-walden/Bad Boll) up to five times daily results in complete recovery in about 82% of patients with conjunctivitis after two weeks of treatment (49391). However, due to the lack of a comparator group, it is not clear if this improvement is due to eyebright or to the natural resolution of conjunctivitis symptoms.
• Cough. Although there has been interest in using oral eyebright for cough, there is insufficient reliable information about the clinical effects of eyebright for this purpose.
• Pharyngitis. Although there has been interest in using oral eyebright for pharyngitis, there is insufficient reliable information about the clinical effects of eyebright for this purpose.
• Rhinosinusitis. Although there has been interest in using oral eyebright for rhinosinusitis, there is insufficient reliable information about the clinical effects of eyebright for this purpose. More evidence is needed to rate eyebright for these uses.
