The dried leaves of the plant, if put into a small bag, and steeped in boiling water for a few minutes, and then applied hot to a gouty part, will quickly relieve the pain; also, they will help to soften the hard concretions which form about gouty joints. If the fresh juice of the Hemlock is evaporated to a thick syrup, and mixed with lanoline (the fat of sheep's wool), to make an ointment, it will afford wonderful relief to severe itching within and around the fundament; but it must be thoroughly applied. For a poultice some of this thickened juice may be added to linseed meal and boiling water, previously mixed well together. Conium plasters were formerly employed to dry up the breast milk, and are now found of service to subdue palpitations of the heart. [250] An extract of Hemlock, blended with potash, is kept by the chemists, to be mixed with boiling water, for inhalation to ease a troublesome spasmodic cough, or an asthmatic attack. In Russia and the Crimea, this plant is so inert as to be edible; whereas in the South of Europe it is highly poisonous. Chemically, the toxic action of Hemlock depends on its alkaloids, "coniine," and "methyl-coniine." Vinegar has proved useful in neutralising the poisonous effects of Hemlock, and it is said if the plant is macerated or boiled in vinegar it becomes altogether inert. For inhalation to subdue whooping-cough, three or four grains of the extract should be mixed with a pint of boiling water in a suitable inhaler, so that the medicated vapour may be inspired through the mouth and nostrils. To make a Hemlock poultice, when the fresh plant cannot be procured, mix an ounce of powdered hemlock leaves (from the druggist) with three ounces of linseed meal; then gradually add half a pint of boiling water whilst constantly stirring. Herb gatherers sometimes mistake the wild Cicely (_Myrrhis odorata_) for the Hemlock; but this Cicely has a furrowed stem without spots, and is hairy, with a highly aromatic flavour. The bracts of Hemlock, at the base of the umbels, go only half way round the stem. The rough Chervil is also spotted, but hairy, and its stem is swollen below each joint. Under proper medical advice, the extract and the juice of Hemlock may be most beneficially given internally in cancer, and as a nervine sedative. The Hemlock was esteemed of old as _Herba Benedicta_, a blessed herb, because "where the root is in the house [251] the devil can do no harm, and if anyone should carry the plant about on his person no venomous beast can harm him." The Eleusinian priests who were required to remain chaste all their lives, had the wisdom to rub themselves with Hemlock.
