An antitussive agent. A composition for relieving, preventing and/or treating cough includes a sufficient amount of Cynanchi Atrati Radix extract as an active component. The effective Cynanchi Atrati Radix extract is prepared by extracting Cynanchi Atrati Radix with water, ethanol, hexane, ethyl acetate or a combination thereof. The crude extract can be further fractioned by ultrafiltration or reverse phase column.

Antitussive agent and method for making the same

A pharmaceutical composition contains a therapeutically effective amount of an active ingredient, in admixture with a pharmaceutically acceptable carrier or diluent for the active ingredient, in which the active ingredient is i) a polar solvent extract of, the polar solvent being water or a mixture of water and methanol or ethanol; ii) an aqueous fraction resulting from an extraction of the polar solvent extract with an organic solvent; iii) an organic eluate by introducing the polar solvent extract or the aqueous fraction into a reverse phase chromatography column, and eluting the column with water and an organic solvent; or iv) a filtrate having a molecular mass less than 30000 in the organic eluate.
