331. _In Jaundice_, especially when it comes on suddenly, after a great mental shock, or after exposure, a few doses of Sal Ammoniac (20 grains every four hours) have often a marked effect. _In Hepatitis and Abscess of the Liver_, Dr. W. Stewart, after considerable experience in its use, regards this salt almost as a specific, and he pronounces it very serviceable in _all cases of Liver Disease_, whether depending on organic change or on functional derangement. The proper period for its exhibition is after the abatement of acute symptoms, and when diaphoresis (sweating) has been freely established, and it should then be administered in doses of 20 grains night and morning. The evidence he adduces in support of his views is very strong. He also speaks highly of its efficacy in _Chronic Dysentery_, and advises its continued use for some time after the disappearance of acute symptoms. (_Madras Journal of Med. Science_, 1870, and Feb., March, and Dec. 1872.) _In Dropsy_, especially in that connected with disease of the liver, or in that following fevers, it may be administered with advantage in the same doses, conjoined with Infusion of Moringa (237), or Decoction of Asteracantha (39). 332. _For Bruises_, _Strains_, _Rheumatic Swellings_, _Enlarged Glands_, _Indolent Buboes_, _Swollen Joints_, _Boils_, _&c._, and _local Inflammations of the Skin_ generally, a solution of this salt in _hot_ water (2 drachms to a pint), kept to the parts for a few hours, proves useful, not only relieving the pain but reducing the swelling. It is also thought to be more effectual than anything else in removing the discoloration consequent on bruises and sprains. This has been noticed especially with reference to blows on the eye (_Black Eye_). It is an important ingredient in the Cold Lotion described in Sect. 265. 333. +Sandal-wood Oil.+ The oil obtained by the distillation of Sandal Wood, Santalum album, _Linn._ Sandal-ká-aitr (_Hind._), Sandal vel Chandan-ká-tél (_Duk._, _Punj._), Safed-chandnúk-til (_Kash._), Sandal-ká-tel (_Beng._), Shandanam-talium (_Tam._), Miniak Chandana (_Malay_). 334. Sandal-Wood Oil is sold commonly in the bazaars, being a favourite native perfume. It has been successfully employed in the treatment of _Gonorrhœa_. Dr. Aitchison strongly recommends commencing with five-drop doses, each dose to be made up separately, and the oil mixed in the fluid it is to accompany with the aid of a drop or two of Liquor Potassæ. It is an excellent remedy, he adds, but must be used with _great care_, as it is apt to produce baneful effects on the kidneys if given in too large doses. It is of great importance to use only good or pure oil; hence it should be procured, if possible, direct from the manufacturer. Much that is sold in the bazaars is adulterated or of inferior quality. It seems well worthy of trial in cases of obstinate _Gleet_. It is best given in a little Omum water or Infusion of Ginger.
