| abstract |
An object of the present invention is to provide an antitussive composition or a composition for preventing cough that has few side effects and effectively suppresses chronic cough and other cough reflexes. A high cough-suppressing effect was observed in Sendangusa plant extracts, particularly hot water extracts. As the mechanism of action, inhibition of anandamide, which is an endogenous substance of capsaicin receptor, or capsaicin receptor antagonism is considered to be involved. [Selection figure] None |
