Bark, or, as it is commonly called, Peruvian bark, is an antispasmodic, tonic, astringent, and stomachic. _Used externally_, it is an excellent detergent for foul ulcers, and those that heal slowly. _Used internally_, it is particularly valuable in intermittent fever or ague, malignant measles, dysentery, diarrhoea, intermittent rheumatism, St. Vitus's dance, indigestion, nervous affections, malignant sore throat, and erysipelas; its use being indicated in all cases of debility. _Doses of its preparations_.--_Powder_, from five grains to two drachms, mixed in wine, water, milk, syrup, or solution of liquorice; _infusion_, from one to three ounces; _decoction_, from one to three ounces; _tincture_ and _compound tincture_, each from one to three drachms. _Caution_.--If it causes oppression at the stomach, combine it with an aromatic; if it causes vomiting, give it in wine or soda water; if it purges, give opium; and if it constipates give rhubarb.
