Pulsatilla (pul-sat-iF-ah) [I-.]. Pasque Flower. 

 Meadow Anemone. The leaves and tops of Anemone

 anemonin, C 15 H, v O B , which depresses the circulation ; 

 in larger doses paralyzes motion. The extract in toxic 

 doses causes convulsions, but anemonin does not. 

 It has been used in amenorrhea, dysmenorrhea, 

 bronchitis, and asthma. It is a valuable alterative. An 



unofficial tincture consists of equal parts of the juice 

 and alcohol. Dose tt^ T V~ X ; of the active principle gr.

 on the aorta. P., Carotid, pulsation of the c: 

 arteries in the neck. It occurs in aortic regurgitation, 

 exophthalmic goiter, anemia, and cardiac excitement 

 P., Epigastric, pulsation in the epigastrium. It is 

 seen in excitement of the action of the heart, in aneu 

 rysm of the aorta, in enlargement of the right heart, 

 in tumors resting on the aorta; in hysteric and anemi. 

 subjects the pulsation of the abdominal aorta m 

 visible in the epigastrium. P., Hepatic, pulsation of 

 the liver at each cardiac systole, due to insufficiency

 of a pulse along the vena' cava. P., Retinal, pulsation

 ing or characterized by pulsation. 



Pulse (puts') [pulsus, the pulse]. The change in the 

 shape and size of an artery due to a temporary in<

 mia. P., Anacrotic. See Anacrotism. P., An-

 on the opposite side. P., Angry. Synonym of if. 

 Wiry. P., Apoplectic, a condition of tin- nuii. 

 artery at the wrist, marked by fulness, without 

 hardness, the vessel generally being dilated and to 

 uous. The predicrotic notch is deep ami close to tin 

 percussion-wave, the dicrotic notch is deep, and th
