A plant indigenous to Europe, w'here it grows in shaded, mountainous forests, on stony, moist ground. The tincture is prepared from the fresh plant in flower. Introduced and carefully proved, upon fifteen provers, by Hesse, published in Stapf's Archives, 1844, reprinted by Trinks in 1847, extracted by Possart in 1851. Suggestions were published by Bussell and Duncan, but not a cure was heard of until 1860, when Coxe, Jr., reported a case of tumor, MSS. In 1875 Berridge reported cures of headaches corroborating symptoms of Hesse.
