Holi is a celebration of the onset of spring. Farmers celebrated happy harvest every year at this time and welcomed the season of spring with celebrations. Since then, the tradition of celebrating with dance, music and colours started.
Once upon a time, the colours used during Holi were prepared from the flowers of trees that blossomed during spring like flowers of ‘tesu’ or ‘palash’ tree and known as gulal. Most of these trees also had medicinal properties and the colours obtained from them were highly beneficial to the skin and body. With the rapid commercialisation of this festival and a strong demand for other colours, artificial colours,consisting of a large number of chemicals, became easily available. These poses serious health issues.
