Ancient Indian Botany: As per Sage Parashar Krushi Shastra or Biological sciences include study of trees, animal and human, because all these have to undergo three stages of life i.e. birth, grown and death.
Indians had deep knowledge about the trees since ancient time. Unlike western botany, one can find very appropriate names for trees. Wood was used since ages for chariots, carts and columns and beams of houses. Ancient texts like Mayamat, Brihat Samhita Sakaladhikar etc contain names and description of more than 250 names of tree which are still available in many parts of India.
