Chafing and Redness

Chafing and Redness, which so often occurs in the folds of children's soft little bodies, should be treated by absolute cleanliness, with the use of a non-irritating soap, and a simple dusting powder to keep it dry. A little absorbent cotton wool may be laid between the folds with the following powder well applied over it: Thymol, one grain; powdered oxide of zinc, one ounce. Or the following application may be used to protect the parts from irritating discharges: Salicylic acid, ten grains; sub-nitrate of bismuth and powdered starch, of each, three drachms; cold cream, a sufficiency to one ounce. Mix, and smear over the surface.

For still more severe cases and mild cases of eczema the following is useful: Powdered tragacanth, fifteen grains; glycerine, twenty-four drops; water to one ounce. To which add: Oxide of zinc, one drachm; carbolic acid, one grain.

Techniques: Sifting

Sifting is frequently required for powdered substances, and this is usually done by employing a fine sieve, or tying the powder up in a piece of muslin, and striking it against the left hand over a piece of paper.

Techniques: To Powder Substances

Place the substance in the mortar, and strike it gently with direct perpendicular blows of the pestle, until it separates into several pieces, then remove all but a small portion, which bruise gently at first, and rub the pestle round and round the mortar, observing that the circles described by the pestle should gradually decrease in diameter, and then increase again, because by this means every part of the powder is subjected to the process of pulverization.

Some substances require to be prepared in a particular manner before they can be powdered, or to be assisted by adding some other body. For example, camphor powders more easily when a few drops of spirits of wine are added to it; mace, nutmeg and such oily aromatic substances are better for the addition of a little white sugar; resins and gum-resins should be powdered in a cold place, and if they are intended to be dissolved, a little fine well-washed white sand mixed with them assists the process of powdering. Tough roots, like gentian and calumba, should be cut into thin slices; and fibrous roots like ginger, cut slanting, otherwise the powder will be full of small fibres. Vegetable matter, such as peppermint, loosestrife, senna, &c., requires to be dried before it is powdered.

Be careful not to pound too hard in glass, porcelain or Wedgwoodware mortars; they are intended only for substances that pulverize easily, and for the purpose of mixing or incorporating medicines. Never use acids in a marble mortar, and be sure that you do not powder galls or any other astringent substance in any but a brass mortar.
