Man has been using plants as a source of food, medicines and many other necessities of life since ancient times. Even to this day the primitive tribal societies that exist depend on the plant life in their surroundings. Though there were investigations of the edible economic values of the higher plants, especially the pteridophytes and angiosperms have been unfortunately ignored. The pteridophytes are used in Homoeopathic, Ayurvedic, Tribal and Unani medicines and provides food, insecticides and ornamentations.
