Where do we find the original provings of Pulsatilla ? In Hahnemann's Materia Medica Pura . See, also, Dunham's Materia Medica . What is the common name of this drug, where does it grow, and how do we obtain the tincture ? It grows in Central and Northern Europe ; its common name is the Wind flower , and our tincture is made from the fresh plant in the same manner as described under Aconitum. It must be imported. Is there not an American variety, and how does it differ from the European ? The American variety is called Pulsatilla Nuttalliana ; its characteristics differ very little from the Pulsatilla nigricans , which is the better proved remedy. Give briefly the general sphere of action of Pulsatilla. Pulsatilla acts prominently on all mucous membranes, producing a catarrhal condition ; upon synovial membranes, producing arthritic and rheumatic conditions. It is a great venous remedy, and in its action on the female generative system it is paramount. It is a great polychrest, and its characteristics are marked, enabling its use in all forms of disease. Give seven pervading characteristics of the drug. 1. Tearfulness ; mild, gentle, yielding disposition. Changeableness and fickleness of symptoms. 2. Aggravation in the evening, after eating and during rest. 3. Relief from motion and in the cool, open air. 4. Paleness of face and chilliness, even with a sensation of heat. 5. All discharges are bland in character, and yellow or yellowish green.
