title: [Herbal medicines against respiratory diseases--traditional empiricism or pharmacological evidence?].
abstract: Sinusitis and bronchitis belong to the most frequent respiratory infections. The relevant guidelines mention the therapy with herbal substances and assign a good activity to cineole and Myrtol as well as to combination preparations with cowslip. There is no final statement of the guidelines' authors concerning the extract of Pelargonium sidoides. Further studies will be necessary to give reliable therapeutic recommendations.
