The history of using plant resources for treating diseases in India can be dated back to the Vedic era, as described in the Rig Veda and the Atharvaveda where effects of herbs/plants are described meticulously. Ayurveda is 'Up-Veda' of Rig Veda and is a complete science of health in itself. According to the World Health Organisation (WHO), 75% of the world population is using herbs for basic health care needs (Pan, 2014). Even in the British Pharmacopoeia, 50% drugs are related to medicinal plants (Pan, 2014).
