Buchu contains two important principles, among others, viz. : volatile oil and bitter extractive (Diosmin), and con- 
sequently has a strong peculiar odour, and a warm and bitter taste. 
The medicinal properties of Buchu are principally exercised in diseases of the urino-genital apparatus, and much 
evidence has been adduced in its favour. It was introduced about 1823, by Dr. Reece, of London. The mode of ad- 
ministration is in powder, infusion, and tincture.

Sear 3 the tree which, by Humboldt and Bonpland, has been asserted to yield Angostura Bark. It grows in the 
ts of uth America, between Cumana and New Barcelona. Hancock has attributed it to another species, the G. 
officinalis ; it is probable, however, that both may yield an analogous bark. 
PR ct article of the Materia Medica is in quilled or flat pieces, having an aromatic odour, and a bitter taste. It 
‘ains volatile oil, resin, and a neutral crystallizable principle, Angosturin. It is called Angostura Bark, from its 
mes io originally from the neighbourhood of the town of that name. Mutis is stated to have been acquainted 
this bark in 1759. It was introduced in England in 1789.
