TARAXACUM 



419 



ACTION AND USES. Poisonous; diaphoretic and expectorant; used in 

 asthma, whooping-cough, and other spasmodic pulmonary affections. 

 In large doses it is a cathartic and emetic, but, being a violent gastro- 

 irritant, it should not be used for these purposes on account of its 

 danger. Dose: i to 15 gr. (0.065 to I Gin.). The latter dose as 

 an emetic. The two species, syphilitica and cardinalis, are used 

 medicinally, the former antisyphilitic and diaphoretic and the latter 

 anthelmintic. Both were used by the Indians.

Tinctura Lobelias (loper cent.), Expectorant 15 TTJJ (i mil).

COMPOSITE. Composite Family 



Herbaceous or woody plants, rarely shrubs, with the flowers in close heads 

 on a common receptacle, and surrounded by a common imbricated involucre. 

 Stamens 5, their anthers united into a tube surrounding the pistil. Flowers of 

 two sorts, strap-shaped or ligulate, and tubular, and hence the family is divided 

 into three tribes: Tubulifloras (flowers tubular in all the perfect flowers, and 

 ligulate in the marginal or ray-flowers), Liguliflorae (all the flowers of the head 

 being strap-shaped, ligulate), and Labiatifloras (with tubular flowers more or less 

 labiate). Fruit an akene.
