Characters. - White tabular lustrous crystals, with a weak odour like carbolic acid, and a sweetish, somewhat pungeut taste. Solubility, 1 in 2 of water; 1 in 20 of olive oil.
Dose. - 5 to 30 gr. every two hours, or single doses of 60 gr. at long intervals.
Externally. - Resorcin is antiseptic and disinfectant, without being irritant, in ordinary solutions (2 to 10 per cent) It has been used as a dressing for all kinds of sores and wounds.
Internally. - It passes rapidly through the system, and is excreted unchanged in the urine by the end of one hour. It causes diaphoresis, and reduces the temperature and pulse for a time in conditions of fever; but has no influence on the normal body heat. Excessive doses cause trembling, singing in the ears, deafness, and mental disturbance. It has been used as an antipyretic in fevers of every kind, and is said to be specially useful in ague; but the drug is still on its trial.
