343. _To prevent Discolorations of the Skin after a blow or fall._--Moisten a little dry starch or arrow-root with cold water, and lay it on the injured part. It should be done immediately, so as to prevent the action of the air upon the skin; however, it may be applied with good effect some hours afterwards. It is a French receipt, and is quite valuable. 344. _A recipe for Neuralgia in the Face._--Make a lotion with half a pint of rose-water and two tea-spoonfuls of white vinegar. Apply it to the part affected, three or four times a-day, using a fresh linen cloth each time. In two or three days the pain will pass away. This has been an effectual cure with many, but as the disease arises from various causes, there is no specific for it. 345. _Eye Water for weak eyes._--Infuse in boiling water, till cold, half an ounce of poppy heads, and the same quantity of chamomile flowers. Strain this mixture, and add two table-spoonfuls of vinegar, and one of brandy. Apply it warm, night and morning. 346. _Another._--Put into a two-ounce phial fifteen drops of laudanum, fill it with two-thirds of rose-water, and one-third of rectified spirits of Mindererus. Use it with a sponge. 347. _To cure a Bruise in the Eye._--Take conserve of red roses, or a bruised apple, put them in a fold of thin cambric, apply it to the eye, and it will draw the bruise out. 348. _Cold or Inflammation of the Eyes._--Mix a few bread crumbs with the white of an egg, put it in a bag of soft muslin, and apply it to the eye. It will afford relief in a few minutes, and generally a cure in a day. It is best applied at night, or when lying down. When removed, bathe the eye well with warm water, using a bit of muslin, not a sponge. 349. _Carvacrol, the new remedy for the Tooth-ache._--Dr. Bushman gives (in the _Medical Times_) the following account of this new compound, which, though well known in Germany as a quick and effectual cure for one of the most worrying ills "that flesh is heir to," is now for the first time published in England. Carvacrol is an oily liquid, with a strong taste and unpleasant odor. It may be made by the action of iodine on oil of caraway or on camphor. A few drops applied on cotton wool (to a decayed and painful tooth) give immediate relief. Carvacrol much resembles creosote in appearance, and is used in similar cases of tooth-ache, but its effect is much more speedy and certain. 350. _To cure Tooth-ache._--A remedy, often effectual, is to fill the mouth with warm water, and immediately after with cold. 351. _Another cure for Tooth-ache._--Powdered alum will not only relieve the tooth-ache, but prevent the decay of the tooth.
