46 BAROSMA CRENULATA 



furnishes a kind of camphor termed barosma camphor. They 

 also contain abundance of mucilage, which originates as in quince 

 seeds and linseed by solution of the cell-walls. A substance 

 called Diosmin or Barosmin has also been described by Landerer, 

 but it requires further investigation. 



Medical Properties and Uses. Buchu leaves act as a slight 

 tonic and aromatic stimulant, and are also regarded as diuretic 

 and diaphoretic. Buchu appears also to have a specific influence 

 on the genito-urinary organs. It is given principally in chronic 

 catarrh of the bladder, irritable conditions of the urethra, pro- 

 static affections, gravel, &c. It has also been recommended in 

 chronic rheumatism, dyspepsia, dropsy, and certain cutaneous 

 affections. It is commonly given in combination with alkalies, 

 as solution of potash. The Hottentots esteem buchu highly on 

 account of its odour, rubbing the powdered leaves upon their 

 greasy bodies.
