What is Banyan?

 

It is an Indian fig tree whose branches produce aerial roots that later become accessory trunks. A mature tree may cover several acres in this manner. For thousands of years, people have used banyans as sources of medicines. Today in Nepal, people use banyan leaves, bark and roots to treat more than twenty disorders. Hindu texts written more than 2500 years ago describe a cosmic ‘world tree’, a banyan growing upside-down with its roots in the heavens. Its trunk and branches extend to Earth to bring blessings to humanity. (Source: Ladders to Heaven by Shanahan, M.)
