Med. Prop. and Action. The Gurjun Balsam is obtained by incisions in the bark of the tree, and is found abundantly in all the bazaars in India. By distillation it yields an essential oil, which, in all its medicinal properties and action, closely resembles Copaiba. It is best given in the form of compound tincture (Beng. Ph.): - ℞ Fssential Oil of Gurjun f3j., Essential Oil of Cubebs f3j., Spirit of Nitric Ether fj.; dissolve.
In Gonorrhoea and Gleet, Sir W. O'shaughnessy employed it in numerous cases, and the results seem perfectly conclusive, that in the treatment of these and other affections of the genito-urinary system, the Essential Oil of Gurjun is nearly equal in efficacy to Copaiba. It generally causes a sensation of warmth in the epigastrium, eructations, and sometimes slight purging. It greatly increases the quantity of urine, which has a terebinthinate odour. He found that some obstinate cases of chronic gonorrhoea and gleet, which had long resisted Copaiba and Cubebs, were cured by this remedy. In the few cases in which I have had an opportunity of trying it, the results have been uniformly satisfactory. It might be advantageously introduced into English practice, as a cheap and efficient substitute for Copaiba.
