Pharmacologia
“ The bark, which is the part used in medicine, yields by analysis tannin, gallic acid, resin, gum resin, bitter extractive, and mucilage. The dogwood is a powerful tonic, and by many practitioners has been used as a substitute for the Peruvian bark. The diseases in which it has been found serviceable are intermitting and remitting fevers, dyspepsia, general debility, &c. It may be given in substance, in doses of ʒj to ʒij—in extract, from 5 to 15 grs. or in infusion or decoction. ”
