The invention provides a dry flowable composition comprising granules of a plant extract, for instance a birch leaf extract or a solidago leaf extract. The granules further comprise a carrier mixture formed from at least one sugar and/or sugar alcohol, a separating agent and optionally a surfactant. The granules exhibit improved dissolution behaviour of the plant extract and are thus suited for oral consumption in the form of drinking solutions. For this purpose, the granules may either be dissolved as such or preferably combined with further excipients selected from edible acids, pH-modifying agents, sweeteners, flavours and/or anti-foaming agents to form a dry flowable composition. The dry flowable composition may for instance be used in the treatment and/or prevention of urinary tract infections (UTIs) such as cystitis.
