a. Bark. 



Note. The bark is used in America as an alterative emetic in scrofula* 

 and cutaneous diseases. It is not official in the U. 3. Pharmacopeia.

510. BETULA LENTA, L. (Cherry Birch, Sweet Birch, Mahogany Birch.) 



a. Bark. 



Note. The bark is peculiar for having exactly the same taste and con- 

 taining the same volatile oil as Oaultheria procumbens. In external 

 appearance it much resembles the bark of Prunus virgiuiaiia, but can at 

 once be distinguished by its taste. It is used in America as a tonic and 

 astringent after dysentery, and in the diarrhoea of children, also for 

 gravel. Artier. Dispent., p. 160. Amer. Journ. Pharm., 1844, p. 243.

. Ditto. (Hard blackish Storax ; Styrax brun, Guib.) y. 

 Note. Styrax calamita is made in Trieste, by mixing three parts of 

 storax bark in coarse powder with two of liquid storax. Specimen h 

 appears to contain rather more liquid storax than usual. Specimens g, h, 

 and t, are the three kinds described by Pereira in his Mat. Med., vol. ii. 

 pt. i., p. 679, under a, /3, y. Specimen i is supposed by him to be a 

 kind of false storax. In odour it resembles benzoin much more than 

 storax. Styrax calamita is frequently covered with silky acicular crystals 

 of stvracin.
