Med. Prop. and Action. Refrigerant and diuretic. It was formerly considered that this salt was useful in affording oxygen to the system; but Wohler obtained it in an unchanged state, in the urine of a person who had taken it, showing that it undergoes no chemical change in passing through the system. O'shaughnessy found it a powerful restorative and stimulant when injected into the veins; and Dr. Stevens ascertained that it communicates an arterial colour to venous blood. He also found that it rapidly caused soreness of the gums. It forms an important article in what is called the Saline treatment of diseases.

In continued and Typhoid Fever, Chomel recommends the internal use of the Chlorate. Dr. Watson§ states that he gives to all his fever patients 3j. of this salt dissolved in Oj. of water, as a daily drink, and that it appears to exercise a favourable influence upon the general character and course of the disorder. In Scarlet Fever, he states that he employs this drink with manifest advantage. Under its use, the tongue, from being furred and brown, or dry, becomes clean and moist. Dr. Copland also speaks highly of its efficacy in the advanced stages of this class of diseases. His estimate of its value is very high.

Lombard* strongly recommends the Chlorate of Potash, in doses of gr. xv. - xviij. every four or six hours. He states that he has seen great benefit result from its use.
Hunt states that the internal use of the Chlorate of Potash has a most beneficial effect. He prescribes from v. to xx. grains for children, and from j. to 3j. for adults, daily. Its good effects are visible in a few days at the furthest. Mr. Hunt believes that it possesses a specific power in this affection. Aperients should be administered at the same time, and the constitution supported. In Gangrenous Stomatitis, Dr. Golding Bird bears witness to its efficacy. In Aphthous Inflammation and Ulcer of the Tongue, arising from anything which irritates the alimentary canal, Mr. Bryant} successfully employed the Chlorate internally (gr. v.) and locally (3j. - 3ij. ad Aq. Oj.). In Diphtheria, it may be given with benefit in full doses, in conjunction with the Tincture of the Perchloride of Iron, and a gargle containing Hydrochloric Acid and Chlorate of Potash may be employed.
