It is best to use Ayurvedic medicinal kajal, made by the following procedure. For preparation, one needs silver or copper plates and lamps, pure cow’s ghee or castor oil and good quality camphor (like bhimseni camphor). A layer of soot is formed on the under surface of the silver/copper plate by holding the plate just above the flame of the silver ghee or castor oil lamp. Slowly remove and collect this soot layer, add a little ghee or butter along with bhimseni camphor and mix properly with a mortar and pestle to form a fine paste i.e., KAJAL.
