POISONS. 195 



It is one of the most deadly of poisonous plants, 

 the toxic matter being found in the root, stem 

 and leaves. 



Symptoms: Great abdominal pain, which grows 

 more intense in a few minutes, is the first symptom 

 noticed. Sweating, frothing at the mouth, con- 

 vulsions, and within half an hour to several hours 

 death takes place in terrible agony. 



Treatment: Relief in the great majority of 

 cases is absolutely hopeless. Raw linseed oil, lard, 

 raw eggs, or any agent to soothe the irritated mu- 

 cous membranes may be given. The potassium 

 permanganate and aluminum sulphate drench may 

 also be administered. Stimulants, such as spirit 

 of camphor, whiskey, ether, aromatic spirit of 

 ammonia or brandy, are indicated. 



7. Choke Cherry. 



Botanical name Prunus demissa. 

 Common name Choke cherry; choke berry. 



This is a shrub with glistening green leaves, 

 not ordinarily harmful, except when famished 

 sheep are driven through thickets of it. It is 

 found usually in gulches. The poison contained 

 in the leaves is hydrocyanic or prussic acid. 



Symptoms: The first symptom noticed after 

 passing through one of these cherry thickets is 

 extreme giddiness; labored breathing, with spas- 

 modic contractions of the bowels and bladder. 

 Spasms continue until death ends the struggle. 

 The attack is speedily fatal if the animals eat of 

 these leaves when their stomachs are empty.
