Azadirachta indica
Some historians and anthropologists assert that many Hindu practices might have been adopted from Adivasi culture. This also includes the sacred status of certain animals such as monkeys, cows, fish, matsya, peacocks, cobras (nagas) and elephants and plants such as the sacred fig ("pipal"), Ocimum tenuiflorum ("tulsi") and Azadirachta indica ("neem"), which may once have held totemic importance for certain adivasi tribes.
