India is a country known for ancient scripts, the number system, invention of zero and vedas. Medicines in india are used by about 60 per cent of the world’s population. These are not only used for primary health care not just in rural areas in developing countries, but also in developed countries as well where modern medicines are predominantly used. While the traditional medicines are derived from medicinal plants, minerals, and organic matter, the herbal drugs are prepared from medicinal plants only. Use of plants as a source of medicine has been an ancient practice and is an important component of the health care system in India. In the Indian systems of medicine, most practitioners formulate and dispense their own recipes, hence this requires proper documentation and research. The encyclopaedia contains 92 medicinal plants which explains their Taxonomic Hierarchy, Introduction, Description, Ayurvedic Properties, Medicinal Properties, Part Used, Chemical composition, Therapeutic uses and Pharmacological Activities.
