A TINCTURE OF THE FRESH BARK OF CORNUS CIRCINATA, L’HER. 
Description.—This shrubby species grows from 6 to 10 feet high. Stem 
erect; bark greyish, verrucose ; branches green, opposite, straight, and slender— 
the younger ones bright green splashed with red, those of the previous year 
somewhat crimson and more or less warty. eaves all opposite, round-oval, 
acuminate, woolly beneath, larger than those of any other species ; ribs and veins 
prominent below and correspondingly indented above. Inflorescence terminal, in 
open, more or less flat, spreading cymes; flowers white. Calyx teeth very short. 
Petals ovate-lanceolate, at length spreading. Stamens longer than the petals. 
Style about two-thirds the length of the stamens; s/gma capitate. Fruit an 
incomplete cyme of spherical, light blue drupes, each hollowed at the insertion of 
the pedicel and where it retains the remains of the persistent style. 
History and Habitat.—The Round Leaved Dogwood grows in copses where 
the soil is rich, being indigenous from Canada to the Carolinas, and west to the 
Mississippi; flowering in the north in June. 
The medicinal use of this species is far less extensive than the last, preceding. 
The Drs. Ives claim* that the bark is tonic, and astringent to a far greater 
degree than any other species of the genus, and that it resembles Cinchona lance- 
folia (Pale Bark) in its action. It has proven, in their hands, an excellent remedy 
for chronic dyspepsia [szc] and diarrhcea. An ounce of the bark will yield in the 
neighborhood of 150 grains of a very strongly-bitter extract; far greater in quan- 
tity, and more bitter than that of C. florida. 
Cornus circinata was dismissed from the U. S. Ph. at the last revision. 
PART USED AND PREPARATION.—The fresh bark is gathered and treated 
as in the preceding species.
