COMPOSITAE — THISTLE FAMILY — YARROW 787 



Fig. 451a. Yarrow {Achillea Millefolium). 1, plant with leaf and flowers. 2, A single 

 head; a, ray flowers; b, a single flower. (Charlotte M. King). 



European name, Nosebleed, was given from the fact that the early writers 

 claimed hemorrhage of the nose followed placing its leaves in the nostrils ; 

 this may have been either due to its direct irritation, or the use of Achillea 

 Ptannica, its leaves being very sharply serrate and appressed-toothed. Mille- 

 folium causes burning and raw sensations of the membranes with which it 

 comes in contact, considerable pain in the gastric and abdominal regions, with 

 diarrhoea and enuresis. An alkaloid having the same formula as achillein has 

 been isolated in A. moschata; a second alkaloid, nioschatin, C^^H^^NO^ is said 

 to occur in the same plant. In Europe sometimes regarded as a forage plant.
