Karanja Oil

Main Uses

As a lighting oil, in pharmacy particularly for skin problems, in tanning and soaps. Soap made from crude oil tends to darken due to a component, Isolonchocarpin, which gives a wine red colour in the presence of alkali. In rural areas the leaves are used to prevent infestation of grains.

The cake after oil extraction may be used as a manure. The presence of a hypotensive principle and a substance producing uterine contraction has been reported.

Much research has been carried out on secondary processing of Karanja oil to overcome some of its shortcomings. All parts of the plant have also been analyzed due to its reported medicinal importance.

Karanja oil, like Neem oil, has been widely used for piscidal, insecticidal, nematicidal and bactericidal activity.
