In the fever for which nitric acid is indicated the heat comes in flushes, and is only on the hands and feet, and there is thirstlessness during all stages. Sweat is apt to be strongly smelling, especially in the axillae and on the feet.
In kidney diseases the indications are haematuria, with frequent strangury, and the odour of the urine is strong -like horses’ urine- or very offensive.
In the skin, nitric acid is useful for foul ulcers, with exuberant granulations and splinter pain on being touched; for warts, especially on the upper eyelids and the backs of the hands, and for a sensation as of a splinter under the yellow curved nails. Offensive sweat occurs on the hands and feet.
It antidotes both mercurius and kali iodatum.
