potash to a cold aqueous infusion of true Winter's bark, a dark some- 

 what violet colour is also produced ; whereas an infusion of Canella 

 alba bark is but slightly altered under the same circumstances. 



Medical Properties and Uses. Canella alba bark is an aromatic 

 stimulant and slight tonic. It is now, however, but rarely used 

 except in combination with tonic or purgative medicines, as aloes, 

 rhubarb, &c. It has been employed in dyspepsia, chronic forms of 

 gout, rheumatism, syphilis, and other cases where a warm aromatic 

 is indicated. In the West Indies it is used by the negroes as a 

 condiment, and is also regarded as useful in scurvy.
