Ethnomedicinal flora: therapeutic significance of major food plants in a remote part of the eastern Himalayas.
The most satisfying areas for the conduct of ethnobotanical studies are remote and isolated parts of the world (Schultes, 1960, 1962). The Himalayas, a remote region where Nature reigns supreme, is a treasure trove of medicinal flora. Ethnomedicinal folklore in the Himalayas has richly contributed to Amchi, Sidha, Unani, and Ayurveda--the indigenous systems of medicine as well as to modern medicine. The Himalayas are the major source of more than 3,000 plant species used in the indigenous systems of medicine. This 2,500 km long mountain complex extending from Afghanistan to Burma is the home of several hundred million people and their centuries-old traditions and cultures. The topography of the area presents logistical problems for an ethnobotanist. However, some ethnomedicinal studies (Hemsley and Pearson, 1902; Steward, 1916; Abrol and Chopra, 1962; Sharma, 1977, 1989, 1993, 1997, 2004; Bhattacharya, 1991; Sharma and Sharma. 2002) reveal the medicinal potential of this region. A global awareness and interest in holistic lifestyle suggests a thorough investigation and understanding of this ancient ecosystem rich in medicinal folklore. This study is an attempt to document the therapeutic significance of some of the major food plants in the eastern Himalayas. Furthermore, the scarcity of modern medicines in these remote areas makes the study of the therapeutic uses of commonly used food plants quite relevant.
MATERIALS AND METHODS
The area under investigation was visited and botanized several times between 1992 and 2005. Villages, small towns, hamlets, mud-huts, temples, and monasteries were the sources of ethnomedicinal folklore associated with the therapeutic utilization of commonly used foods and spices in the region. Local village folks, priests, and practitioners of indigenous systems of medicine consulted represented a wide spectrum of the society. Local gatherings and social events were attended to learn about the therapeutic uses of various foods. Old manuscripts available in monasteries and temples also were probed for the centuries-old traditions associated with these practices. Voucher specimens were prepared and deposited at the herbarium facilities at the University of Tennessee, Martin, Martin, Tennessee. Taxonomic identification of the plant material was confirmed by the local clinics and practitioners of indigenous systems of medicine. The area under investigation is a remote, sparsely inhabited part of the eastern Himalayas bordering Bhutan, India, Nepal, and Tibet lying at 26[degrees]30'-29[degrees]30'N and 88[degrees]50'-90[degrees]50'E and includes valleys and peaks ranging between 2,000 and 4.000 m.

The World Health Organization estimates that 80-85% of the people of the world depend upon traditional indigenous systems of medicine for their primary, very basic health needs (Farnsworth, 1986). Indigenous medicines are inexpensive and many developing countries are encouraging their use. Furthermore, it is imperative that the conservation of the habitat and the sustainable use of its resources become our concern so that new medicines may be identified. The Himalayas represent a delicate and pristine ecosystem that is under much anthropogenic stress. This calls for a strong commitment for its ethnomedicinal exploration. The high costs associated with modern medicine are straining the economies of many developed nations and have moved medical care beyond the reach of much of the world's population.
A major concern among infectious disease specialists throughout the world is the possibility of untreatable plagues of resistant organisms (Weil, 1996). In view of the present crisis in modern medicine and emphasis on alternative therapies, especially in the industrialized world, it seems that medicinal folklore associated with plant species in remote parts of the world should become a major focus of research. Almost half of all prescriptions dispensed in the United States contain substances of natural origin, and over 50% of these medications contain a plant derived active principle (Farnsworth, 1977). Reserpine, vincristine, and vinblastine are some of the examples of medicinal compounds derived from the flora of these remote ecosystems. Many of the so called "wonder drugs" of the 20th century are increasingly ineffective today. This is a plea for encouraging a systematic documentation of traditional ethnomedicinal folklore where we may find new and even more effective "wonder drugs" for the treatment of human afflictions.
