CARBOLIC ACID. 215 ;

itself does not appear to undergo any change in its corpuscular
elements. It is in part consumed in the body, and the products
of its combustion are excreted in the urine. Solutions of car-
bolic acid of adequate strength will check suppuration, and cor-
rect the fetor of ulcers, and has a beneficial effect on bone as
well as on the soft tissues in necrosis, etc.
Therapeutic Uses.—Internally, it is employed for nausea and
vomiting due to an irritable state of the stomach, in scarlatina,
measles and smallpox, pyrosis, etc.; as a gargle in diphtheria;
as an inhalation in chronic nasal catarrh, hay asthma, whooping-
cough, phthisis, etc. ; as an injection in chronic cystitis, primary
syphilis, erysipelas, pleuro-pneumonia and uterine diseases ; as a
lotion in gangrenous and other ill-conditioned ulcers, carbuncle,
poisoned wounds, burns, skin diseases, scrofulous ophthalmia
and itching of the skin.
Dose.—Of crystallized carbolic acid, gr. y^ to gr. j, largely
diluted. A better form, however, is one drop of the crystallized
acid, liquefied by heat, in one ounce of mucilage, three times a
day. The dose of glycerite of carbolic acid {Glyceritum Acini
Carbolici)., made by rubbing together .5ij of carbolic acid with
Oss of glycerine, is TTLiv.
The dose of carbolic acid water {^Aqua Acidi Carbolici)^ f5x
of the glycerite, dissolved in distilled water, enough to make the
mixture measure a pint, the dose is foss to f 5j.
Impure carbolic acid is employed for disinfectant purposes.

Sulphophenol.—Sulpho-carbolic acid, C«H, (OH) (SOaOH)^^
CgHgSO^, is produced by the action of sulphuric acid on phenol,
and is considered to be a very efficient antiseptic and disinfect-
ant. The addition of acids, particularly sulphuric, to crude
carbolic acid of different strengths, increases its antiseptic and
disinfectant properties, and considerably increases its solubility.
Twenty-five per cent, of crude carbolic acid, mixed with an equal
quantity of concentrated crude sulphuric acid, gives the best results,
and renders it a cheap and effective disinfectant and sterilizer.
