Ethno-medicinal application of plants in the eastern region of Shimoga district, Karnataka, India
Introduction
Plants are important sources of therapeutic drugs and play a significant role in the survival of the tribal and ethnic communities. India is rich in cultural and floristic diversity and also a store house of ethno-botanical knowledge. Large sections of Indian population still rely on plant-based medicines as they are abundantly available, economical, and have little or no side-effects (Sinha, 1996, Dubey et al., 2004) in addition to their cultural acceptability (Pal and Shukla, 2003). Of late, medicinal plants have gained global importance in alternative health-care system, for their proven and effective curative properties. Certain plant drugs used in modern medicine have ethno-botanical background (Dev, 1997, Fabricant and Farnsworth, 2001). Certain important scientific evaluations of plant species include bioactive compounds like artemisinin from Artemisia annua, vincristine and vinblastine both isolated from Catharanthus roseus and shatavarin-I from roots of Asparagus racemosus and curcumin from Curcuma longa (Dev, 1997). Globalisation and changes in human life style have tremendous ill-effects on traditional culture in India. Hence, medico-botanical knowledge of different ethnic and folklore communities and tribals need urgent documentation, before it is completely lost.
The wealth of ethno-botanical knowledge has been documented from various parts of India (Jana and Chauhan, 2000, Katewa and Galav, 2005, Udayan et al., 2005, Das and Tag, 2006, Dabagar, 2006, Tiwari and Pande, 2006, Samy et al., 2008). In Karnataka state, the knowledge of ethno-medicinal value of plants with various tribal and rural folk communities for treating various diseases and disorders has been documented to some extent (Bhandary et al., 1995, Bhandary et al., 1996, Harsha et al., 2002, Parinitha et al., 2004, Parinitha et al., 2005). A perusal of these reports suggest that documentation of this knowledge in Karnataka is incomplete, and particularly, it is so in the Shimoga district of Karnataka. In this paper, an attempt has been made to collect and document the traditional medicinal plant knowledge of local herbal healers of different castes and communities residing in the eastern part of Shimoga district.
