Pulsatilla acts prominently upon all the mucous membranes of the body, and upon the synovial membranes, the veins, the eyes, the ears, and the generative organs of both sexes, more especially the female. In the mucous membranes a catarrhal process is established, the secretions are modified, sometimes retarded, more often increased, the functions of the organs they supply are disturbed, the nervous system becomes irritated and depressed, and, as a result, we obtain the numerous symptoms of deranged digestion, respiratory troubles, genitourinary disturbances, and catarrhal affections of the eye and ear, which so fully characterize the action of this drug. On the generative system Pulsatilla exerts a marked action outside of its catarrhal sphere, due probably to its influence over the cerebro-spinal system. On the synovial membranes it produces arthritic or rheumatic inflammation, and in the veins varicose conditions. The most essential feature of Pulsatilla is its action upon the female generative organs, especially when occurring in females of a mild, yielding disposition, inclined to weep.
