CHAPTER II 

 BANUNCULACEZEl. 



Traveller's Joy (Clematis Yitalha L.). The extent to which 

 this species is poisonous is not clear, though all parts are stated to be 

 poisonous, acrid and narcotic, while the juice tends to blister the skin. 

 It is remarked by Comevin that it is less poisonous ia spring, when the 

 ass and goat browse on it to a considerable extent without serious 

 trouble, than later, when it cannot be eaten without danger. 



Toxic Principle. Traveller's Joy appears to contain strongly 

 poisonous substances which have not been closely investigated. 

 CrreshofE found a Saponin in the leaves^. The poison is dissipated 

 by heat. 



Symptoms. When eaten in quantity the young shoots are diuretic, 

 violently purgative, causing dysentery, and in rare cases death. 

 Applied to the exterior it is irritating and even vesicatory. (Comevin.)

Anemone {Anemone sp.). Both our native species of Anemone 

 appear to be more or less poisonous in character: the Wood Anemone 

 or Wind Flower {A. nemorosa L.), and also the Pasque Flower {A. 

 Pulsatilla L.). These plants, the former of which grows in woods and 

 damp shady spots in fields, and the latter on chalk downs and lime- 

 stone pastures, may on occasion be taken by stock in early spring, when 

 green herbage is not too plentiful, but deaths appear to be rare, even if 

 they have occurred. All parts of the plants contain a toxic principle, 

 which is volatile and destroyed by drying. 



Toxic Principle. The toxic substance is stated to be Anemone- 

 campJior (oil of Anemone) which imparts a bitter taste to the plants, 



^ Kobert states that various species of Clematis, Ranunculus, Anemone, and also 

 Caliha palustris and Trollius europaeus, contain Anemonal or Pulsaiilla-camphor, 

 which causes strong local irritation, burning and swelling in the mouth, vomiting, 

 intestinal inflammation, etc.
