The resin of Shorea robusta, called Rάla in Sanskrit and Dhuna or rάl, in the vernacular, is regarded as astringent and detergent and is used in dysentery, and for fumigations, plasters, etc. The resin thrown over the fire, gives out thick volumes of fragrant smoke, and is much used for fumigating rooms occupied by the sick. It is also a common practice with natives to burn some ral in their rooms every evening, about the time that chirags or lamps are lighted, as also during the worship of idols.
In the dysentery of children rάl is recommended to be given in doses of about twenty grains, with an equal quantity of sugar or treacle.1
Ral enters into the composition of some plasters and ointments. The following is an illustration. Take of rάl, rock salt, treacle, wax, honey, bdellium, red ochre and clarified butter, in equal parts, boil them together and prepare an ointment.2
