Some important medicinal plants from different regions of Rajasthan.
Collection of important medicinal plants from different regions of Rajasthan. Introduction– Rajasthan has a large population of about 5, 64, 73, 122 crore. Around 80 percent live in villages which utilizes local medicine. The people of Rajasthan can be broadly divided into ; those living into extreme wheather condition as in Western Rajasthan and others in milder climate. Rajasthan has rich biodiversity consisting of a large number of plants, some of which are used for their medicinal value. Although flora of Rajasthan has been compiled by Bhandari (1978) and Sharma (1976) but detailed information about their medicinal properties are lacking. A large number of medicinally important tree species are present on Aravalli hill range and other areas including less hopitable North–West Rajasthan. An attempt was made to characterize tree species of the region and detailed pharmacognostical studies on them are in progress. Several tribes of Rajasthan used the traditional system of medicine. The tribals who depend on forest (mostly their surrounding vegetation) wealth are the real custodians that safeguard the medicinal plants till now. Rapid deforestation caused by over–harvesting and exploitative trade of medicinal plants has significantly reduced the availability of the medicinal plants in arid and semi–arid region of Rajasthan (Srivastva, 1977 ; Singh , 1983 ; Sinha, 1994 ; Pandi et al., 1996 and Harsha et al., 2002). Generally, wasteland plants are called as weeds and said to be unwanted and undesirable plant species. On the contrary as suggested by ‘Ayurveda’ has said, “No plant of this world is useless”. Knowledge about the medicinal properties of these plants is confined to tribals only. Generally the folk people are well acquainted with the medicinal properties of their surrounding vegetation particularly for their well being (Schultes, 1962 ; Jain, 1965 ; Masih, 1997 ; Sanghi and Kumar, 2000 ; Shivani and Kumar, 2000 ; Mishra and Kuamr, 2001). Rajasthan where 80 percent of its people live in the rural areas and cannot afford to the luxury of costly modern medicine. They depend on vegetation surrounding them and make perfect uses of them for their medicinal needs. (Upadhyay, 1997). The present investigations were undertaken for collection of important medicinal plants from different regions of Rajasthan. Material and Methods– Detailed survey has made in all districts in Rajasthan and the information regarding use of medicine has been documented. The plants were identified by using standard monographs and flora (Sharma, 1976 and Bhandari, 1990).

All the plant species are deposited in Herbarium, Department of Botany, University of Rajasthan, Jaipur.
