title: [Phytotherapy of respiratory tract diseases].
abstract: Herbal medicines have been used in cough due to their antitussive and expectorant activity. Antitussives act either centrally on the cough center of the brain or peripherally on the cough receptors in the respiratory passages. The antitussive effect of many herbs results from the content of mucilage, which exerts protective and demulcent activity. The activity of expectorant herbs results primarily from their influence on the gastric mucose (saponins and ipec alkaloids). This proves reflex stimulation which leads to an increase in the secretion of bronchial glands. Volatile-oil type expectorant herbs exert a direct stimulatory effect on the bronchial glands by means of local irritation with antibacterial activity. In colds and flu, herbs containing volatile oil can be used; also, volatile oils are ingredients of syrups and liquids as well as external phytomedicines in the form of liniments, ointments, and inhalations. The paper shows the herbs and phytomedicines present on the Polish market used for the treatment of respiratory tract diseases.
