Acidum Nitricum Dilutum (U. S. P. lO%). Tonic, antiseptic, astringent, and alterative. It stimulates the intestinal glands. In doses of from 5 to 20 I, well diluted, it is useful in chronic hepatitis and intestinal in digestion and when oxalates are deposited in the urine. Where diarrhea persists after an attack of indigestion, it is a most useful remedy. Where constipation exists, hydrochloric acid is preferable.

In small doses (1 to 5 I) the dilute acid is alterative, markedly stimulating metabolism. For this reason its prolonged administration in small doses is indicated in chronic rheumatism, syphilis, old ulcers, chronic bronchitis with profuse expectoration, and in chronic liver complaints as an adjuvant to other treatment.
