 whole of this plant is bitter, especially the bark of the root. It is 

 tonic, diaphoretic, and febrifuge. All the parts of the plant are

 Cornus florida. Dogwood; box-tree. The properties of this 



article are astringent and tonic, and it has long been used as a sub- 

 stitute for Peruvian bark ; and even cornine has been prepared from 

 it, like quinine. It may be administered for the same purposes, and 

 in the same dose with quinine.

228. Cornus circinea. Round dogwood ; possesses similar proper- 

 ties with the above.

MitcTiella repens. Creeping chequer berry; two-eyed chequer 

 berry. This plant is sometimes mistaken for the Gaultheria procum- 

 bens, they both being evergreen ; but this is a creeping plant, and 

 that erect. This has no aromatic property, while the Gaultheria is 

 very spicy. This is a most valuable diuretic, and is extensively used 

 for the cure of dropsy. The red berries are mildly astringent, and 

 are used, also, for the cure of diarrhoea. The Indian Dr. Louis uses 

 it in combination with the Spiraea alba, a species of hardhack, for 

 the cure of salt rheum.
