Liquid preparation containing crude-drug extract

摘要

The present invention relates to a liquid preparation containing crude drug extracts in an amount of 5 to 50 w/v % in terms of a dry extract weight based on the whole amount of the liquid preparation, characterized by containing saccharides in an amount of 5 to 40 w/v % based on the whole amount of the liquid preparation and adjusting a pH to 4.5 to 5.5. This liquid preparation is suppressed in generating precipitate and suspended content with the course of time even if the crude drug extracts are contained in a high concentration and which is stable over a long period of time.
