Gargling is an efficient means of treating the mucous membrane of the pharynx and tonsils. The quantity of fluid taken into the mouth at a time should be about what would make two swallows for the individual, and half a glassful of sedative or cleansing gargles should be used each time.

After deep inspiration, take the liquid into the mouth, throw back the head, and allow it to flow into the pharynx. Swallow once with the mouth open, then slowly expel the breath through the liquid for about half a minute, the mouth remaining open. If gargling, i. e., expelling globules of air through the fluid in the pharynx, is tiresome to the patient, he can swash the liquid around the throat with nearly as good therapeutic results, although flic naso-pharynx cannot be so reached.

To cleanse the naso-pharynx, after gargling, the head should be thrown quickly forward and down and the liquid will reach this cavity. Or the liquid may be snuffed or gently poured through the nostrils into the throat and so cleanse the naso-pharyngeal vault.

Mouth-washcs are made of the same liquids used for gargling, and are used with the object of treating the mucous membrane of the mouth and gums.

Gargles are soothing, astringent, and antiseptic.

Examples of soothing gargles are: warm physiologic saline solution; hot milk and water, equal parts; the Liquor Antisepticus of the Pharmacopoeia; Seiler's solution; any mild alkaline or mucilaginous solution.

Examples of astringent gargles are: tannic acid, or any drug containing it, solutions; potassium chlorate solution; diluted alcohol; weak nitrate of silver solutions; tincture of iron solutions; glycerine solutions, etc.

Examples of antiseptic gargles arc peroxide of hydrogen solutions; saturated boric acid solutions; Dobell's or other phenol solutions, etc.

Setter's solution is made by dissolving a Seiler's tablet in one-third of a glass of warm water. Each Seiler's tablet weighs one gram and contains:
