Indian archaeologists have discovered that a mix of hemp with clay and lime plaster has prevented the ancient Ellora caves from degrading over the supposed 1,500 years they have been in existence.
The use of hemp helped the caves and most of the paintings remain intact.
Using two techniques such as Fourier transform, infra-red spectroscopy and stereo-microscopic studies, researchers were able to conclude that hemp, commonly known as had helped in preventing insect activity at Ellora.
The study indicates that many valuable properties of hemp were known to Indians in the 6th century. Hemp was extensively used in Ellora as well as by the Yadavas, who built the Deogiri fort in the 12th century. Hemp was not used in the Ajanta caves, which are about 30 rock-cut Buddhist structures dating back to the 2nd century BC. Rampant insect activity has damaged at least 25% of the paintings at Ajanta.
