A tincture of allied berries was used of old by ladies of fashion in the land of the Pharaohs, as discovered among the mummy graves by Professor Baeyer, of Munich. This had the property of imparting a verdant sheen to the human iris; and, perhaps by the quaint colour-effect it produced on the transparent cornea of some wily Egyptian belle, it gave rise to the saying, "Do you see any green in the white of my eye?" [389] At one time _Belladonna_ leaves were held to be curative of cancer when applied externally as a poultice, either fresh, or dried, and powdered. It is remarkable that sheep, rabbits, goats, and swine can eat these leaves with impunity, though (as Boerhaave tells) a single berry has been known to prove fatal to the human subject; and a gardener was once hanged for neglecting to remove plants of the deadly Night Shade from certain grounds which he knew. A peculiar symptom in those poisoned by _Belladonna_ berries is the complete loss of voice, together with frequent bending forward of the trunk, and continual movements of the hands and fingers. The Scotch under Macbeth sent bread and wine treacherously impregnated with this poison to the troops of Sweno. The plant bears other titles, as "Dwale" (death's herb), "Great Morel," and "Naughty Man's Cherry." The term "Morel" is applied to the plant as a diminutive of _mora_, a Moor, on account of the black-skinned berries. The _Belladonna_ grows especially near the ruins of monasteries, and is so abundant around Furness Abbey that this locality has been styled the "Vale of Night Shade." Hahnemann taught that, acting on the law of similars, Belladonna given in very small doses of its tincture will protect from the infection of scarlet fever. He confirmed this fact by experiments on one hundred and sixty children. When taken by provers in actual toxic doses the tincture, or the fresh juice, has induced sore throat, feverishness, and a dry, red, hot skin, just as if symptomatic of scarlet fever. The plant yields atropine and hyoscyamine from all its parts. As a drug it specially affects the brain and the bladder. The berries are known in Buckinghamshire as "Devil's cherries." [390] NUTMEG, CINNAMON, GINGER, and CLOVES. The spice box is such a constant source of ready domestic comforts of a medicinal sort in every household that the more important, and best known of its contents may well receive some consideration when treating of Herbal Simples; though it will, of course, be understood these spices are of foreign growth, and not indigenous products. Cinnamon, Nutmeg, Ginger, and Cloves, claim particular notice in this respect. "Sinament, Ginger, Nutmeg, and Cloves, And that gave me my jolly red nose." _Beaumont and Fletcher_. Cinnamon possesses positive medicinal as well as aromatic virtues. What we employ as this spice consists of the inner bark of shoots from the stocks of a Ceylon tree, first cultivated here in 1768.
