“Bandhūka presents four varieties based on the colours of its flowers viz., black, white, yellow and red. It is a good antipyretic rug, besides being used in preventing bad celestial effects and the effects of bad spirits. It is said to be employed in the prayers of the Sun God [Savitṛ], to please him”.
