Geranium, Crane's bill. This is a valuable drug, but its preparations are unsatisfactory. In domestic practice the fresh root is boiled in milk, and in this form is moderately satisfactory. Few fluidextracts of this root are made from sufficiently recent material; the eclectic tincture is active, but is very liable to disintegration. The solid extract in 6 to 8 gr. doses or I gr. pills of geranin is fairly effective.
Geranium is actively astringent, employed in gastro-enteric troubles with excessive mucous discharges and in throat difficulties as a gargle. It does not cause dryness of the mucous surfaces, and has no unpleasant influences. Besides the ordinary use in diarrhea and as an astringent, the eclectics esteem it in night sweats of tuberculosis, while the homeopaths employ 30 I. doses of the mother tincture in gastric ulcer, claiming that it will destroy the pyogenic membrane. It is an excellent remedy in tubercular hematuria. In general, it may be said that this agent is unduly neglected, and even though its preparations are not ideal they are useful. F.e., 10 to 60 I.; ec. tr., 3 to 30 I. ; @, 10 to 60 I. Green root, f.e., 3 to 30 I. It is difficult to make a full strength fluidextract of geranium.
