title: Antitussive activity of the fruit extract of Emblica officinalis Gaertn. (Euphorbiaceae).
abstract: The antitussive activity of Emblica officinalis Gaertn. (E. officinalis, Fam. Euphorbiaceae) was tested in conscious cats by mechanical stimulation of the laryngopharyngeal and tracheobronchial mucous areas of airways. The results showed that at a dose of 50 mg/kg body wt. perorally, the cough suppressive effect of E. officinalis is not unambiguous. A higher dose (200 mg/kg body wt.) of this substance perorally was more effective, especially in decreasing the number of cough efforts (NE), frequency of cough (NE/min(-1)) and the intensity of cough attacks in inspirium (IA+) and expirium (IA-) was more pronounced. These results showed that the cough suppressive activity of E. officinalis is dose-dependent. We could also demonstrate that the antitussive activity of E. officinalis is less effective than shown by the classical narcotic antitussive drug codeine, but more effective than the non-narcotic antitussive agent dropropizine. It is supposed that the antitussive activity of the dry extract of Emblica officinalis is due not only to antiphlogistic, antispasmolytic and antioxidant efficacy effects, but also to its effect on mucus secretion in the airways.
