iy] Primulaceae, Oleaceae, Convolvulaceas 49 



Toxic Principle. The plant contains the glucoside Cyclamin 

 (C20H34OH)), and a saponin-hke substance (Pammel). Van Rijn says 

 it contains two glucosides. 



Symptoms. The plant has an irritating effect on the intestines and 

 a stupefying effect on the nervous system. Cornevin states that it is 

 never taken by the larger domestic animals in quantity sufficient to 

 cause poisoning.

OLEAGE.^. 



Privet (Ligustrum vulgare L.). The facts as to the poisonous 

 character of Privet are by no means clear, but Taylor records a case 

 in which three children who ate the berries were attacked by violent 

 purging, and a boy and girl died. Turner observed a case in which 

 horses died after eating Privet. 



Toxic Principle. The Privet is stated to contain the poisonous 

 glucosides Ligustrin and Ligustron, not mentioned by Van Rijn, who 

 says it contains Syringin ( 017112409), while Pammel (1911) adds the 

 bitter glucosidal principle Syringopicrin (C26H24O17). 



Symptoms. In horses Turner observed loss of power in the hind 

 limbs, with a pulse of 50, temperature 102° F., slightly injected mucous 

 membranes, and dilated pupils, with death in 36 to 48 hours. The 

 berries are stated by Miiller to cause sickness and diarrhoea.

CONVOLVULACEiE. 



Bindweeds {Convolvulus sepium L. and C. arvensis L.). The 

 creeping rootstocks and foliage, as well as the seeds, are held to be more 

 or less poisonous if eaten in quantity, and as long ago as 1872 Olver 

 recorded {Veteritiarian, 1872) that pigs which ate freely of Convolvulus 

 died. These species, when eaten in considerable quantity, appear to 

 be cathartic and purgative, causing symptoms resembling those due to 

 jalap.
