Definition

Dogwood, the common name of many of the larger of the forty or so species frequently cultivated, of hardy shrubs, trees, and herbs that comprise the genus Cornus (family Cornaceae). The above species grows from 12–30 ft. high in Canada and the United States. The slow-growing and compact wood is covered with a rough and brownish bark used for many purposes. The leaves are smooth ovate, dark green above and pale beneath; the flowers are in bloom April to May, and are of a greenish-yellow color and constitute the chief beauty of the tree in the springtime. The action of the Dogwood flowers is close to Chamomile for their soothing, tonic, and adaptability to weakened and debilitated conditions of the stomach. The fruit is an oval drupe of glossy scarlet color, containing a nut with two cells and two seeds, which the birds are very fond of. The bark is broken into small squarish blocks. The chemical quality of the bark is tannic, and gallic acids, resin, gum, oil, wax, lignin, lime potash and iron, cornice is its active principle. Buds are buttonlike which occurs on upturned horizontal branches in winter.

Uses

It is much used as substitute for Peruvian bark (Cinchona), from which quinine is made, and may be used when the foreign remedy is not to be had, or when it fails, or when it cannot be administered. By some, Dogwood is prized for ague, but it is better adapted to the diseases caused by weakness of the stomach and bowels, by inducing circulation of healthy blood to the parts, removing effete matter, vitalizing the tissues and speedily removing pain from the diseased parts. To overcome water brash and other stomach weaknesses, capsules combined with Golden seal (Hydrastis canadensis) and Ginger (Zingiber) in powder form can be taken after meals. “Dogwood, or Green ozier, exerts its best virtues in the shape of an ointment”—Dr. O. P. Brown (1875). Both are effective. Internally, 1 teaspoonful of the bark in 1 cup of boiling water, steeped for ½ hr. Drink ½ cupful upon retiring at night, hot or warm, or take a mouthful three times a day. 1 or 2 cupfuls may be taken. Of the tincture, ½–1 fl. dram.
