How to Use Medicinal Plants of the Udayagiri Hills

The plants which are used to cure diseases are called medicinal plants. This property of plants is due to the presence of certain chemicals called phytochemicals which include alkaloids, glycosides, flavonoids, volatile oils, vitamins, resins, gums etc. These chemicals terminate the growth of micro organisms by obstructing one or many metabolic activities of microbes.

The history of the use of plants in medicine can be traced back to the ancient civilizations or pre-Rig-Veda times. Thee earliest written record of the preparation and use of medicinal plants is in Rig-Veda (4,500-1600B.C.). Indo-Aryans acquired knowledge of the medicinal properties and uses of plants while searching for the therapeutic uses of soma whose juice is mentioned as Aushadi. Vedic Aryans were familiar with about 100 species of plants. Atharvana Veda documented more details on medicinal herbs and their varied utility. This was followed by the monumental contributions like “Charaka Samhita”, Sushruta Samhita etc. Plants form the major resource in the preparation of drugs in many ancient systems of medicine like Ayurveda, Unani, Homoeopathy, Naturopathy, Siddha and Allopathy.
