According to the method of production of plant extracts, the plant substances blend is extracted with water and the extract is pasteurised and preserved. The plant substances blend contained in filtration bags (2A, 2B) is phase-extracted in such a way that the final extract is obtained by extraction of the plant substances blend contained in one filtration bag (2A; 2B) with the water extract of the other filtration bag (2A, 2B). According to an advantageous arrangement, the phase extraction contains at least one operational phase in which the filtration bag (2A, 2B) containing a leached plant substances blend is leached with water in an extraction vessel (3A, 3B) forming a partial extract and the other filtration bag (2b, 2A) containing a new plant substances is leached with the partial extract in the other extraction vessel (3B, 3A) forming final extract.
