In summary one can say: as with all the preparations, the individual composition steps work together not additively but multiplicatively. What arise are substances that are not variations of properties fixed by natural law and stemming from the past, but properties that enable development within living interconnections. In the case of the oak bark preparation, this is the newly gained property of strengthening the members of the plant's being and thereby prophylactically counteracting plant diseases.
